7mm rem mag with Triple shock (Barnes)
 

I recently purchases a new Remington 700 chamber for 7mm Rem Mag. I really am looking to load up the new TSX from barnes. I was wondering if anyone has loaded this and what powder and how much of it you loaded. I plan on the 140 Gr. for muleys this fall. Any guidance will be appreciated.

RE: 7mm rem mag with Triple shock (Barnes)
 

Hello pahntr. Very bad bullet choice IMHO. Go with the 140 gr Nosler BT with RL22.....you will love this combo and the deer will be very dead. Regards, Rick.

RE: 7mm rem mag with Triple shock (Barnes)
 

You would be hard pressed to find a better bullet than the 140gr tsx.They are very accurate in most rifles,expand well even on smaller game,and hold together as well as any bullet available.I will however agree with r-22 for use with this combination.

RE: 7mm rem mag with Triple shock (Barnes)
 

I have been told that the new TSX is the greatest revolution to bullet tech in recent history. I chose the 140 Gr. because I believe the other weights up are a bit too heavy for deer. how much rl22 do you all think i should put behind that bullet.

RE: 7mm rem mag with Triple shock (Barnes)
 

I use the tsx myself and it has been very impressive both with it's accuracy and it's performance on game.The 140grtsx is a good choice for deer or even elk and moose.As for a powder charge,I don't have your rifle,so I can't tell you what charge will work best in your rifle or even what charge will be safe in your rifle.In the rifle that I loaded the 140gr tsx for,66gr was very safe and produced good velocity,but as I said,this was not your rifle.I would start at around 62gr of r-22 and work up from therewatching for pressure signs.

RE: 7mm rem mag with Triple shock (Barnes)
 

My rifle is a Remington 700. all standard for now. any other questions go ahead and post.

RE: 7mm rem mag with Triple shock (Barnes)
 

Unfortunately all 700 remingtons are not the same and they don't all shoot the same load equally well or develop the same pressure with a given load.The chamber dimensions, internal barrel dimensions,and throat lengths vary enough to make each gun an individual.

RE: 7mm rem mag with Triple shock (Barnes)
 

Sorry if I seem ignorant, but i am not to savy on reloading. I just want a guide line to start at so I'm not f-ing with it forever. I do have a buddy who is really pretty good with all of this stuff that will help, but any other help is always a good thing.I have always been partial to Remington firearms. I guess I didnt realize how indivdual they really are. Anyways, thanks for the help, and any more is appreciated.

RE: 7mm rem mag with Triple shock (Barnes)
 

Actually,all rifles are individuals reguardless of the manufacturer.Some behave very similarly,and some quite different,but the only way to find out what load a rifle likes,is to actuallyshoot different loads in that rifle.

RE: 7mm rem mag with Triple shock (Barnes)
 

i guess i see where you are comming from. I will just take the press to the range with me and figure it out then.

RE: 7mm rem mag with Triple shock (Barnes)
 

I don't take my press anywhere.I make up some test loads and then go to the range and see if the gun likes them and if there are any pressure signs.In your case,I would probably loadthree rounds with 62gr,three with 63gr,three with 64gr,three with 65 gr and three with 66gr.Fire the 62 gr loads first watching for pressure signs.If everything looks good,let the barrel cool fully and fire the 63 gr loads,then 64gr,then 65gr,and finally the 66gr loads,letting the barrel cool fully between each group and watching for pressure signs with every shot.

RE: 7mm rem mag with Triple shock (Barnes)
 

What exactly are you refering to when saying, "pressure signs"? Up to this point, I have only shot factory loads. In PA I only hunted whitetails with my .308 in moderate to heavy cover, so a 150Gr. factory load with core-lokt bullets was great. But now I am stationed in Utah and will be making longer more, open shots, for the most part, soI want more precision. Plus, 7mm factory loads are just plain expensive! At any rate, thanks for all the help andI will let you know what happens.

RE: 7mm rem mag with Triple shock (Barnes)
 

If you aren't very familiar with pressure signs,you need to do some research before attempting any reloading.Below are some links that might help.

RE: 7mm rem mag with Triple shock (Barnes)
 

I've used the 140 gr. TSX in my 7mm Mag Sako. 66 grs. of H4831sc along with Fed215M primers in Nosler brasshas worked quite well. Killed the biggest whitetail in my life with this combination last year. As stubblejumper points out, however, this load may not be safe in your particular rifle. Start lower and work up to it if you decide to try it. BTW, these are loaded .050" off the lands as Barnes recommends.

RE: 7mm rem mag with Triple shock (Barnes)
 

I think you need to buy yourself a Barnes reloading manual. Or a loadbook for the 7mm Rem Mag. Read the books and the forewarnings and go from there.

Like everyone has said, its hard to tell you a load, because no one wants to be responsible if something f's up.

The 140gr TSX is a great bullet, and it will serve you well. My Browning A-bolt 7mag shoots the 160gr TSXs into ragged holes at 100 yards. I have yet to try the 140s but I could guarantee they'd shoot equally as well.

I'd use the Fed 215M primers and RL22 as well......RL22 has the repuatation of the "most accurate" powder for a 7mag.

RE: 7mm rem mag with Triple shock (Barnes)
 

RL22doescome highly recommended, but I for one have not had much success with it in the two 7 mags I've reloaded for.It gave good velocity, but accuracy wasnothing to write home about. It also seems less consistent lot to lot than most other powders I've used.

RE: 7mm rem mag with Triple shock (Barnes)
 

I have loaded for at least eight or ten 7mmremmags.R-22 has worked well in most but not all of them.I have found that some rifles prefer imr 4350 or imr4831.

RE: 7mm rem mag with Triple shock (Barnes)
 

IMR 4831 has worked particularly well for me, but I haven't tried it yet with the 140 gr. TSX. I guess I should.

RE: 7mm rem mag with Triple shock (Barnes)
 

Man a barnes tsx in a 7mm would be a lethal elk round

RE: 7mm rem mag with Triple shock (Barnes)
 

If you don't have one, I would purchase a good reloading manual such as the Hornady or Speer manual. I am loading the TXS in the 7mm-08 this fall but I am going to try the 120 grain TXS for Mule deer. Good luck.

RE: 7mm rem mag with Triple shock (Barnes)
 

Hopefully Ill find out, Im leaving for an Idaho elk hunt on sunday, taking 7mm Rem mag and my 7-08, the mag with 150gr TSXs and the 08 with 140gr XLCs. Hopefully Ill whack my second elk with my 7-08.

RE: 7mm rem mag with Triple shock (Barnes)
 

I have had good success with the 140 TSX, RL22 and 215GMM'sin my 7mm rem mag.63-70gr of RL22 but work up slowly!! It wouldn't hurt to take your experienced handloading buddy with you to the range when testing loads to help with pressure signs, etc.

I'd start at .050" off the lands for seating depth.

I have harvested 2 bull elk, bull moose and2 deer so far with the 140TSX.

Good luck

RE: 7mm rem mag with Triple shock (Barnes)
 

I will be heading back to PA next year for a white-tail hunt and propose this question. Being as it is much thicker cover in PA should I consider a heavier TSX for these conditions? Or will the 140gr be fine? What do you all suggest?

RE: 7mm rem mag with Triple shock (Barnes)
 

If you hit branches,it won't matter.The 140gr tsx works well on elk and moose as well as deer.

RE: 7mm rem mag with Triple shock (Barnes)
 

That’s what I figured; I have this load worked out to shoot perfect clovers at 100. And it will keepright close to subMOA out to 400 yards. (Off a bench)

RE: 7mm rem mag with Triple shock (Barnes)
 

Barnes makes great bullets but there are a couple of things that make them different. Barnes copper alloy is softer than jacketed bullets. Barnes copper will foul your bore badly if you've got copperfouling from other type bullets in your bore. Completely de-copper your bore before shooting Barnes or they'll shoot like doo-doo.
Second, do just like the Barnes manual says: Seat the bullets between .030" and .070" from the lands. I seat most Barnes loads right at .050".
They shoot well and do a good job on game.

RE: 7mm rem mag with Triple shock (Barnes)
 

I too have mine seated at .050 off the lands. I also realize the problem with fouling and clean the heck out of the gun after every range session. When I was load developing, I would clean the thing till the patch came out white between every different load. (5 shots or so) They perform VERY well on paper, as for game, I don’t yet know I was waiting on my PA hunter safety card to be re-issued (I lost the original) and Utah sold out the deer tags. I should be there right now! GRRRR!

Anyways, this is my usual cleaning regiment


Allow the gun to cool completely
Fill the barrel with the 'Break-Free' foaming bore cleaner
Allow it to do its job (15 min)
After the wait I run the bore brush through 15-20 times
Then about 3-5clean dry patches
Then Break free on a patch till they come out clean
The dry patches until they are perfectly dry[/ol]
I'm not this particular while on the range, but I do like to see clean patches before trying the next load

RE: 7mm rem mag with Triple shock (Barnes)
 

PersonallyI don't touch my bore on the range during development. I clean it when i get home. I do take a rod and patch when working with a new rifle just to see if running a preventive oil patch down it does anything to my POI once I have my loadbut other than that nah. The only time I don't touch after hitting the range is if I have a bore that likes to be fouled and will be hunting. I'll shoot out the number of fouling shots required to settle it and put it her away till the hunt is finished.

RE: 7mm rem mag with Triple shock (Barnes)
 

There is no better bullet than Barnes. Nobody else even a close second. I load the 7mm with a 120 grLazzeroni Lazerhead. Madeby Barnes for Lazzeroni. (a coated triple shock) You can get them from Midwayusa.com. I take 7mm Weatherby cases (has to be Wby headstamp)and fireform them in a 7mm Rem Mag gun (10 gr of Bullseye and cram cornmeal on top with a little cotton ball to keep it in place,no bullet) then trim to Rem mag length. My load is 83.5 gr RL 22 and velocity is 3850 fps with no pressure signes. (using a browning BPR 7mm Rem mag) Yes the Triple shock grooves in these coated bullets are awesome. Also these solid copper X bullets hold together 99+ percent, always expand double diam and nearly always go out the other side of a deer. Seat them .050" from the lands (starting) for best accuracy. Yes this load in this rifle shoots well under an inch @ 100 yards.

My son's middle name is Remington!

RE: 7mm rem mag with Triple shock (Barnes)
 

Well, this is going to make me persona nongrata in the Barnes nest, however, I have never fired a decent group with any Barnes Copper bullet. My old Sako .243 (the most unfussy rifle that I have ever owned) hates them (85gr). Three '06's, a Sako, Parker Hale and a Rem BDL hates them....two inch groups). Sorry, but I just gave up. The same load in the 243 with a Sierra shot 1/2 inch groups. Yes, I have a Stoney Point AOL gauge, Yes I tried various powders and yes I seated them from 5to 50 thousandths off the lands. Tried 7 different powders. That's my story and it's pretty sad. Unless somebody out there can come up with some magic, I will not use Barnes Bullets. Up here in NC Northern Mo, I need 400 yard consistant accuracy.......Barnes bullets just don't measure up.....for me. Regards, Rick.

RE: 7mm rem mag with Triple shock (Barnes)
 

Thats increadably impressive numbers your talking. E-mail me more about that technique you use with the WBY brass. Last time I got some brass off E-Bay, it had some 7mm WBY MAG headstampted brass in it. Would love to get a 3800 fps load.

Here are my load stats now

7mm Rem Mag
Rifle- 700 ADL
Case- Frontier or W-W
Bullet- Barnes TSX 140 gr
Charge- 67gr RL-22
Primer- Federal Match Large Mag Rifle
FPS- ~/= 3200 fps
I'm shootin perfect clovers at 100 yds.

Nice Middle Name on the kid!!!!! I'm a Remington Slut! Only thing I shoot other then my Grand Daddys 32 win spcl. You gotta understand that though.

RE: 7mm rem mag with Triple shock (Barnes)
 

Rick
I grew up there in NC Northern MO. 10 mi N of Salisbury. I too was weaned on beanfield fence rows. 1/4 mile shots were the norm and hard to get closer. 2" @ 100 yds is a scrap/loaner gun there.

RE: 7mm rem mag with Triple shock (Barnes)
 

It is just fireforming the 7mm Weatherby in a 7mm Rem mag chamber. The rem mag chamber is slightly larger than the 7mm Weatherby but the Weatherby brass (and it has to be Weatherby headstamp not RP or Win etc) is thinner so after fireforming you now have more capacity. I take a fired 7mm Wby case, a mag primer 10-15 gr of Bullseye powder then fill with cornmeal and pack a cotton ball on top to keep the cornmeal in place and firein the 7 rem. I then trim to 7mm Rem specs and load. You can trim the case a little first if you want but I don't go full short length.

Also I use the Lazzeroni Lazerheads. (lazzeroni.com)They are made by Barnes dimensionally undersize and 3 grooves cut in them then Robar plates them with "NP3" for lube and to bring them back to size. Then Lazzeroni sells them for $1 apiece. Midwayusa.com $53 for 50. I have worked up to 85 gr of RL22 with NON-Magnum benchrest primers (they have the little capitol B on them) but came back to 83.5 because I need the accuracy. after 5 loadings the primers are still tight @ 83.5.

If anyone has a lot of time you can try front ignition loading and reduce recoil, narrow the velocity spread and increase accuracy, but the max velocity does not seem to rise for me. There is a good explanation in the 10th ed Cartridges of the World book page 482. Oh yah there is less muzzle flash and the cases are to hot to pick up with wimpy fingers. (another story)

RE: 7mm rem mag with Triple shock (Barnes)
 

I tried multiple powder, primers and brass and could not find a combination with the accuracy I want. I recently started loading the Nosler AccuBonds and can't belive the accuracy and nock down power of this bullet.
