270 wsm is it flatter than a 7mm rem mag
 

i looked at a box of 270 wsm's today and liked what i saw, but is it better than my 7mm mag?

RE: 270 wsm is it flatter than a 7mm rem mag
 

It is probably flatter then the 7mag, but you can't shoot as big of bullets out f it. The .243 your looking at is probably flatter then the 7mag out to 400 yards or so.

RE: 270 wsm is it flatter than a 7mm rem mag
 

RR- You don't think? I'll have to go check some numbers;)

RE: 270 wsm is it flatter than a 7mm rem mag
 

the 270 wsm is faster than the 7mag but my 243 wssm is faster than both

RE: 270 wsm is it flatter than a 7mm rem mag
 

In real life the 7mm rem mag will edge out the 270wsm in trajectory(be it slight with the lighter bullets). The 7mm rem mag will open up the gap at 150gr and up bullets. It is a little moreadapatable asit shoots 140-175gr bullets well and at a good clip. Where as the .277 tops out at 150's. Yes, a few 150gr plus offerings available for .277 but I would be willing to bet the 270wsm wouldn't preform very well above 150gr much like the 300wsm doesn't above 180gr's due to seating a longer bullet in short fat case.

Both are good choices for deer. While the.277 isadequate for elk and moose the.284 is better suited based on bullet choices alone for larger then deer!

I wouldn't want both and wouldn't trade a 7mm rem mag for 270wsm either but I hunt more then whitetails or mulies. I own a 270 win and 7mm rem mag, the .270has been back up duty for a number of years.I have decieded to sell it, asI have other rifles and will use the funds to start the process of building a .257 cal deer rifle.

ha ha ha the 243 flatter than my 7mm mag lol nope no way ill go shooting with you any day of the week to proove you wrong

RE: 270 wsm is it flatter than a 7mm rem mag
 

TheFederal catalog shows the .270 WSM shootsjust barelyflatter than the 7mm Rem Mag with an equal weight bullet. Note that the WSM does it in a short action.

Remington backs that up but the gap is even wider.

RE: 270 wsm is it flatter than a 7mm rem mag
 

Where can you even compare a 243 to a 7mag??? It is just not going to happen. Let it be a shortmag or not. The 7mag willl shoot flatter, hit harder, and do it more efficiecntly than any 270 will do, short mag or not.

RE: 270 wsm is it flatter than a 7mm rem mag
 

I just researched this a lot and ended up buying a 270 WSM !! I whitetail hunt mostly so I really compared 140 grain bullets from Federal, Winchester, and Remington ! The 270 wsm "on paper" shoots a little flatter and has a little more energy down range !! I don't know about the real world much but @300 yards my gun has less drop than my buddy's 7 mag...........but it's not a whole lot .....probably 2" of difference !! I think he was shooting 140's like me but he may not have been............I'll have to ask him !!

RE: 270 wsm is it flatter than a 7mm rem mag
 

I posted this about 2 weeks ago and nobody responded. So here it is agin, look at the new remington accutip 150 .270wsm. it says (if you believe factory numbers) that it only drops 28in at 500 yards.Now that is smoking if it true.

RE: 270 wsm is it flatter than a 7mm rem mag
 

They are to close to call. According to Hornady, If the both shoot a 150 grain bullet and both are zeroed at 300 yards, the 270 WSM will drop 9.7 inches at 400 yards while the 7 Mag will drop 9.9 inches.

Its so close that it only depends on whos ballistics you use. For sure, no critter would ever know the difference.

RE: 270 wsm is it flatter than a 7mm rem mag
 

RE: 270 wsm is it flatter than a 7mm rem mag
 

YES, you are correct. I have found the same thing. The 150 grain ballistic tip and 160 grain Accubond seems to fire the best. The Remmington Accutips look appealing also.

RE: 270 wsm is it flatter than a 7mm rem mag
 

You say a 270win can't out do a 7mm mag in trajectory? If your buying factory ammo you better start reading ballistics. Most 7mm mag ammo using a 150gr bullet isn't even hitting the 3000fps unless you buy the premium ammo. 270 in 130gr bullet standard ammo fly's 3050fps. So that being said its all a matter of what weight of bullet and how fast it's going. If your a reloader you can make both rounds into trajectory busters. As long as the accuracy is there. It's all about getting used to the cartridge and knowing the drops. You could shoot a 375 h&h at 400yds no problem as long as you know the gun.

270wsm pffffffffffffft short fat lil stubby. 130 gr 3217fps hmmmm I wonder if i should trade my 270win that's shooting 130gr 3288fpsfor it. I don't think so.

RE: 270 wsm is it flatter than a 7mm rem mag
 

NO, it isn't. At least, not if you load your own ammo for the 7 Mag. The 7 Mag. has two basic advantages overthe .270round: It holds more powder; it shoots larger-diamter bullets. Both of these work together to provide the potential for higher velocities with bullets of equal or greater ballistic efficiency. These factors work together to provide both a flatter trajectory and more down-range energy.

The ONLY advantage I see to the WSM or SAUM's is they can be used in a shorter action (lighter rifle). This is generally mox-nix to me, because I mostlyhunt with a single-shot anyway, so length of the round doesn't matter.

RE: 270 wsm is it flatter than a 7mm rem mag
 

I'm not stuck comparing factory load data. The truth is that today's 7mm Rem. Mag. commercial loads have been "wimpified" to the point that they barely beat the 7X57mm Mauser! I can safely get 3350 FPS from my 26" Ruger No. 1 7mm Rem Mag. using 140-grain Nosler Partition bullets,and 3050 FPS with the 175-grain Nosler Partition bullets. I doubt that there are ANY commercial loads for the .270. 7mm, or .300 WSM's that will beat that 175-grainer for energy on target at 300 yards (2430 ft/lb). I zero this load to be +3.5" @ 100 yards. It hits +4" at 200, is dead on at 300, and is -9.5" at 400 yards. I can aim halfway up the chest of a broadside elk all the way out to 400 yards, and kill him with 1 shot. Since the rifle is a single-shot, this is the way I like it. For all smaller game, I use a single-shot 7X57mm Ruger No. 1A, unless I'm shoot ing my .73 cal. flintlock Jaeger!

RE: 270 wsm is it flatter than a 7mm rem mag
 

Thats with a 250 yd zero. Big difference with a 100 yd zero or even a 200 yd zero.

RE: 270 wsm is it flatter than a 7mm rem mag
 

This is kind of a coin-flip comparison. When shooting bullets of about the same sectional density (130 gr. .270 vs. 150 gr. 7MM) they are about the same - a slight edge in trajectory to the .270 WSM. But in real world scenarios, there is very little difference in trajectory or thump - especially if you use premium bullets. Good campfire conversation material . . . . .

RE: 270 wsm is it flatter than a 7mm rem mag
 

Actually I just compared the balistics in the same weights and types of round. The 270WSM beats the 7 Mag in terms of fps and foot pounds of energy along with trajectory and wind drift naturally. Now if 270 WSM were more widely available and less expensive then 7mm Rem Mag, then it would be the logical choice. If you love the WSM action then the 270 WSM benefits the most over its predecessor 270 Win

RE: 270 wsm is it flatter than a 7mm rem mag
 

hmmm this is verry interesting but thats factory right what would happen if we handloaded both say shot 150 grainers i think we could get the 7mm mag to outperform the 270wsm. am i right? i just am haveing a hard time seeing that the 270 msm cant be beaten by the 7mm mag in 150 grain area theres no doubt that the 7mm kills the 270 wsm in heavier bullets i have seen listings for the 7mm mag just under 4000 fps i cant remember if it was 150 grain bullets or if it was 164gr but what do you guys think

RE: 270 wsm is it flatter than a 7mm rem mag
 

The 7mm Rem. Mag. offers me nothing. If I had to pick and choose, give me the 270 WSM.

RE: 270 wsm is it flatter than a 7mm rem mag
 

7mm rem mag is much hotter. Its just got more powder.

RE: 270 wsm is it flatter than a 7mm rem mag
 

4000fps??? With 150 or 164 (???) :D?? Put down the crack pipe and slowwwwwly step away... that IS funny though MM



Why do people even bother responding to this guy? He haspoisoned the entire forum and continues to do so with new names daily and people just keep responding. I wonder if this is someone from another forum trying to kill this board or if it is somebody that is really that f'ed up...

RE: 270 wsm is it flatter than a 7mm rem mag
 

Only if you are stuck shooting factory ammo, and choose to believe the MV claims they are making to sell the shorties!

RE: 270 wsm is it flatter than a 7mm rem mag
 

Methinks you are whistlin' Dixie here! The 7mm Rem Mag. MIGHT be able to produce "just under 4000 FPS". But that would be with 50, and not 150 grain bullets!

My 26" 7mm Maggie can do over 3300 with a 140-grain bullet, and I have gotten 3420 with oneparticular lot of Norma N205 powder which is long departed. No currently available powder in this country will do as well as that old N205 did.

RE: 270 wsm is it flatter than a 7mm rem mag
 

Very good point. It's bad enough that premium ammo is up to around 40 to 50 dolars a box now. All WSM ammo is around that price so I'll stick with my plain ole 7mm Rem Mag and not get caught up in all of the balistic hoopla. Heck, I'm only shooting at deer for no more then 300 yards currently anyway.

RE: 270 wsm is it flatter than a 7mm rem mag
 

Once again, people are believing the hype and propaganda that the ammo manufacturers are spewing forth. I'll say it again the only way to know is to shoot the load in YOUR gun over a chronograph and to shoot at the ranges mentioned. Anything else is just heresay.

RE: 270 wsm is it flatter than a 7mm rem mag
 

They don't lie about their ballistics. Any idiot with a $50 chrono can check it. It's common knowledge that they use SAAMI chambers (minimum dimensions) and 24" test barrels (onmost rounds). It says as much on the catalogs.

The other thing about factory ammo, especially the short mags is that they can get better performance from the same weight of powder than a handloader can. They use different powders that we don't have access to, and they use different shaped powders, sometimes in a blend that we cannot reproduce. Plus, they can load compressed powder charges with their special equipment (Hornady Light Mag etc).

It mostly comes down to believing what you want to believe, not what's actually happening.

RE: 270 wsm is it flatter than a 7mm rem mag
 

Hahahahah.
Ya my truck gets 24 mpg like they claimed, were responsible for global warming, the government has nothing to do with the price of gas, wal-mart guns are grade 2, scent lock suits do work, and Bill Clinton never lied either.

RE: 270 wsm is it flatter than a 7mm rem mag
 

Obviously you never have,I findpublished ballistics to be optimistic at best. My chrony hasshown very few loads be it factory orreload datathat meet the statedvelocity.

I agree thndrchicken the only real way is firing them from your rifle over a chronograph and at the distances you intend to shoot. Anything less is only a guess. I have seen 2 identical rifles/loads at different MV's on many occasions, their is more then just powder in a case that factors into the performance equation and the only way to knowis by testing!

RE: 270 wsm is it flatter than a 7mm rem mag
 

HA HA! Good one but yeah, we are to blame for global warming (not Bush like the Dem's would quickly state) and yes the government gets like 50 to 75 cents per gallon depending on where you live. A large portion of this is to fund the military. I will give you credit for the Bill Clinton comment though, "Now listen, I did NOT have sexual relations with that woman". Ahhh, power is a beautiful thing!

.243 vs. 7mm Mag

I'm not as dumb as you guys thought, uh??:D;);)

RE: 270 wsm is it flatter than a 7mm rem mag
 

270wsm vs. 7mm Rem mag..............coin toss.

RE: 270 wsm is it flatter than a 7mm rem mag
 

Both are very close. When dealing with factory loads, which most hunters use, I would give a little edge to the 270 WSM. I would purchase this caliber in a heart beat over a 7mm rem mag. If they perform almost identicall, why wouldn't you go for a shorter case? Shorter bolt loading time with second shots, less powder=less recoil, lighter gun, more accurate(which some of you laugh at). WSM's provide a possitive alternative imho. Probably the best all around deer caliber on the market.

RE: 270 wsm is it flatter than a 7mm rem mag
 

The very slight difference in velocity (flat trajectory) between the 270 WSMand 7mm Rem. Mag. can vary from one rifle to the other simply because the velocity of individual barrels, even of the same cartridge, can vary up to 200 fps.

So what does this mean? It means some270 WSMs will shoot faster (flatter) the 7mm Rem. Mag. and some 7mm Rem. Mags will shoot faster than 270 WSM.

I own and like them both. Which is flatter shooting could depend upon how fast or slow yourrifle barrel is verses your buddy's rifle barrel.

RE: 270 wsm is it flatter than a 7mm rem mag
 

what does that show ? Nothing, the 7 mag is flatter than a .243 with a much heavier bullet. I think the only bullet in the .243 flatter than the 7 mag would be a 55 gr, which is not suitable for deer.

RE: 270 wsm is it flatter than a 7mm rem mag
 

Now that was funny. Zrexpilot-that was funny.

I do not want to offend anyone who can, but I personally believe most hunters can not hit a five gallon bucket at 300, and for sure at 400 yards. And this argument is over what? two or three inches? Come on guys.

Now for the real comment, and I am gonna get it for this one. Both of these cartridges are just 30 caliber wanna-be's. Tom.

RE: 270 wsm is it flatter than a 7mm rem mag
 

well i saw that loading on a site on the internet and i havent seen it in my own gun so yeah dont get all hooked up on it 4000 fps is pretty fast it could be a fulse loading im not sure i never tried it like i said

RE: 270 wsm is it flatter than a 7mm rem mag
 

Quicker to rechamber..really??? I mean you actually thinkSA makes that much difference?? I haven't but then again I don't worry that much about the second as the first is the one that matters;)! Less powder, UM ok? Compared to a 270 win it is actually more powder and a 7mm rem mag not a lot of difference, take a look at some reloading data. Recoil thats where they get you, you assume less powder means less recoil but what you forget to factor in is: a lighter rifle!! This will increase the energy of recoil and may actually feel like more.I have never bought the shorter action is more accurate, it very well maybe to a benchrest shooter eeking out every 10th of an inch but for a hunter I haven't seen it personally.

No doubt the .277cal is great but so are many others. Deer aren't to picky so I say anything 1/4 bore up is just fine if deer are on tap. Though where the .277cal suffers slightly is in larger then deer and I think the wsm does nothing to address this area as like other wsms due to the case the larger for caliber bullets do not perform in short fat case cartridges, meanwhile they will perform in their older brothers. So personally if I wanted a .277 for more then deer I'd stick with the 270 win personally as it will perform, meanwhileI think the 270wsm will suck hind teet just like its 300wsm cousin does with anything over 180 grs.

I agree the fullfil a niche but I believe they are marketed for Deer Primary hunters and the response here sort of solidifies that in my mind.

TOM...anything .308 bullet will do a .284 will as well!;)

RE: 270 wsm is it flatter than a 7mm rem mag
 

you really think a 308 will out do a 7mm mag or what did you mean by that
