flattest trajectory
 

ok just wondering. whats the flattest shooting factory load/caliber?

RE: flattest trajectory
 

If we' re talking magnums, Gotta be Lazzeroni Firebird or Warbird.

RE: flattest trajectory
 

I' m not sure. The Lazzaronis are not what I' d call " factory" . I think the 25.06 would have to be one of the flattest.

Dang, now see what you' ve done. I' m gonna have to get out my manuals and look now. I hate when that happens!! ;)

RE: flattest trajectory
 

The 257wby mag,7mmultramag and 30-378 would all be contenders if you are not including lazzeroni.

RE: flattest trajectory
 

It used to be the 7mm Remington Ultra Mag. Don' t know if its been replaced at the top or not.

RE: flattest trajectory
 

ok now how about in a varmint caliber. i was always under the impression you couldent top the 22-250 but what abou the new 243 and 223 wssm?

RE: flattest trajectory
 

The 30-378 Weatherby is awfully tough to beat on that one. If you want to pay less than $80 a box for ammo it is probably the 7mm or 300 Ultra Mag.

RE: flattest trajectory
 

If your going to include the lazzeroni then you need to include the .257 hot tamale. A new round that is flat enough to kill deer at 500yards without holdover or scope adjustment.

RE: flattest trajectory
 

Why would you NOT consider the Lazzeroni calibers as " factory" ? They are built by three different builders (Lazzeroni has his guns " assembled" by some of the greatest in their specific fields, Sako and Savage build the other two.) he has a network of dealers on several continents and a QUICKLY growing customer base. LOL, that being said I will put my Warbird with 130 Xbullets up against ANYTHING available over the counter!!! (BTW the 257 Scramjet Lazz isnt as fast and since those light 25cal bullets dont retain velocity as well, the cartridge is' nt as flat as the Warbird with 130s or the Firebird with 120s. But a friend of mine shoots 350# whitetails on his Kansas lease with his L2000 Scramjet and it IS a neat round. The huge case simply is overbore with anything much under 7mm bullets tho so a large performance increase over a hot 257 Wby isnt very well noticed. Its strength lies in the fact that it just as easily drives 120grain 257s as easily as it does 95 grainers.)

If we are talking about " wildcats" I am VERY interested in the .375/50BMG. A 275grain bullet leaving the muzzle at 5100fps MUST be fun (despite barrel washing rather quickly! :D ) and Godawfully powerful and flat [:o][:o][:o]

Because you can' t go to Wal-Mart, or any place like it, and buy the ammo off the shelves.

RE: flattest trajectory
 

Why are so many threads turning into pi$$ing matches tonight? I am going back to finish organizing my hunting cabinets. At least the the only arguing there is with myself about where to put what.

RE: flattest trajectory
 

So Wal-Mart is the deciding factor in what is a " factory gun/caliber" and what is' nt? Danny if thats the measure then you must exclude most WSM and WSSM, Rem Ultra and Short ultras, most any Weatherby mag and rounds like the STW as Wal-Mart typically has a poor or non-existent selection of such calibers and ammo.

So what is the flatest " Johnny Wal-Mart hunter" caliber? Well since the flatest thing they typically carry ammo for is the 7mag and 300Win Mag then those MUST be the fastest and baddest on the market... yeah thats it! Gosh I' m ditchin my Warbird and forgettin the plans for a 50. I think I' m gonna get a 30 Carbine.

Nevermind, Corvettes are the fastest cars on the roads because thats the fastest thing the Chevy dealers carry (those Ferrari and Lamborghini dealerships are simply figments of our imaginations :D )!!!

RE: flattest trajectory
 

I can see how the Lazyroni cartridges get their speed:D........load em with specially lubed bullets ie. nP3 from robar and run them at extreme pressures. I looked at the warbird reloading data and the loads run from 66,000 t0 67,000+ psi at a mild 70 degrees:eek:.......[:o]wonder what the pressures would be at 100 degrees?[:o]. Are these cartridges listed with SAAMI and have their approval?

RE: flattest trajectory
 

What about the .220 Swift? We are talking about going to Wal-mart and finding shells for it right?

RE: flattest trajectory
 

The flattest trajectory was a simple question that turned into an arguement between people which neither one asked the question. Chevy, Farrari, warbirds, or Remington ADL' s chambered in a .270...Who cares. Just a simple question.

RE: flattest trajectory
 

Hard to beat the 7mm' s due to their high Ballistic Coefficientcy. The 175g Partition has a BC of .519! I didn' t see any in my Nosler reloading manual that has a higher BC and, pushing at a very high velocity, will ensure a very flat shooting round. For a factory offering the 7mm Ultra Mag would be hard to beat unless you added in the Lazzeroni 7' s;

http://www.lazzeroni.com/ct_lacart.htm

They have a 120g Warbird that is going almost 4000 fps and, with a 300yd zero, only drops 14" at 500 yards. Of course, as was mentioned, they use a lubed bullet to keep the pressures from maxing out and are very expensive (~$100/box).

RE: flattest trajectory
 

Geeze, I wasn' t trying to start a pissing match. And if you' re going to quote someone, look at the entire quote. I said, Wal-Mart, or some place like it. Where can you go to get Lazzeroni ammo? You certainly can' t go to just any sporting goods outlets, or even very many gun shops and pick up their ammo. Does Winchester make their ammo? How about Remington, or Federal, or even Hornady?

And as far as your comparison on cars, you' re a goober. We all know the fastest " domestic car" is the Dodge Viper. And there' s alot more places to buy Lamborghinis and Ferraris than there are Lazzeronis.

RE: flattest trajectory
 

Atually the fastest " domestic" car would be the Saleen S7.
0 to 60 in 3.5 seconds and a top speed over 200 mph.

Sorry I couldn' t resist.;):D

http://saleen.com/home/home_set.htm?x=1

As far as the flattest shooting cartridge, loaded by one of the major manufacturers, would probably be the 30-378 Wea. mag. Of course these cost just as much as Lazzeronis' cartridges do.

RE: flattest trajectory
 

UUUM...The Grand National GNX had the same 0-60 so you can' t forget it too....:D:D;)JDinAB

my votes for the 7mm.

RE: flattest trajectory
 

Which 7mm?7mm refers to the bore but does not describe a cartridge.As for the gnx the 0 to 60 time is listed at 5.5seconds for a stock vehicle.

RE: flattest trajectory
 

I have found that shooting across pavement will provide a flat trajectory for almost any rifle.:D

RE: flattest trajectory
 

The fastes bullit that I have ever fond is th 30/06 with a acsellarater sorry about the spelling but it is 4080 fps out of a 22inch berrel

RE: flattest trajectory
 

Now that we have made the circle, the flatest shooting most reasonable priced and easiest to find ammo for and will cover all the average hunters needs would be a 22-250 and a 270 Win. You can go hotter and more expesive but why would you need to. Flat shooting and tons and tons of energy don' t kill a thing that the old standards won' t for a fraction of the money. They also won' t turn the average hunter into a super marksman who can take any practical advantage of such ballistics.

RE: flattest trajectory
 

Dont forget the Porsche 928 S4
Released in 1987 as the fastest production car. Production car means you go to any dealership and the car is on the lot. You pay and you drive.

A heavy ass car with power leather interior, cruise control....you can drive it for days and never get tired....not to mention it will do 171 mph without feeling like you are driving in a truck.

RE: flattest trajectory
 

Ok I' ve been doing some research myself on this flattest tragectory.

In a 7mm STW with 120grain zeroed at 100 you get a 27.0 inch drop at 500.
In a .243 with 55 grain zeroed at 100 you get a 29.1 inch drop at 500


.220 swift = 33.8 inch drop at 500 with 40 grain bullet, the weakest 1457 fps
.22-250 = 32.7 inch drop at 500 with 40 grain bullet, the fastes 4150 velocity
.243 = 29.1 inch drop at 500 with 55 grain bullet
.257 wby = 30.1 inch drop at 500 with 87 grain bullet
.270 wby = 32.3 inch drop at 500 with 100 grain bullet
.300 wby mag = 31.9 inch drop at 500 150 grain bullet, the stongest 4316 fps
7mm STW = 27.0 inch drop at 500 with 120 grain bullet
7mm STW = 31.3 inch drop at 500 with 140 grain bullet, the slowest 3500 velocity
6mm Rem = 30.2 inch drop at 500 with 55 grain bullet

RE: flattest trajectory
 

i knw for a fact the 300 ultra mag is flatter shooting than all other ultra mags.but i think the 30-378 is the flattest.

RE: flattest trajectory
 

and to whoever said that the 257 can kill a deer at 500 yards does not know what he is talking about.Any gun can kill a deer that far holding right on but you will have to zero it in at that range.no gun can be zeroed in at 150-200 yards and hit a target at 500 holdin right on.maybe .50 bmg.

RE: flattest trajectory
 

Footballboy5571-As the owner of two 300ultramags and a 7mmultramag I can tell you that with equal barrel lengths the 7mmultramag will shoot slightly flatter than the 300ultramag.The 300ultramag does however carry more energy.

RE: flattest trajectory
 

lol, the 50? " BOY" you need to spend some more time readin ballstics I reckon. The 50 has HORRIBLE ballistics when compared to most SuperMags. The saving grace of the 50 besides its AWESOME power is its accuracy, penetration and wind-drift defying heavyweight bullets.

BTW the 30-378 AINT the " Top Dawg" on the block! ;)

RE: flattest trajectory
 

Out of factory and affordable rifles the flatest shooting would probably be the 7mm Remington Ultra Mag.

The 257 WM and 30.-378 WM would also be right there.

I believe 1 of the flatest shooting caliber/cartridge in the world would have to be the 6.5mm/50 BMG. Not sure how long the barrel would last though??

RE: flattest trajectory
 

Want something affordable, get a 25-06, buy some Hornady Light Magnum 118 grain rounds for it. Average rifle and 23 dollars box for ammo and put the rest of the money in your pocket.
