7X57 bullet choice
      #218643 - 30/10/12 11:03 AM

what bullet for the 7X57 at around 2700 FPS I'm sitting on the Barnes 140gr. TSX or the 140gr. Swift A-Frame. I hunt whitetail and hogs for now but will be using my rifle for elk and hopefully plains game somewhere in the distant future.

I really liked the idea of my BRNO putting 160gr. TSX out at 2,700fps using H4831, for both moose and elk. That load put 3 into consistent 1/2" groups at 100 meters off the bags. I didn't get around to putting any into into elk or moose prior to trading it for another CZ 527 in .22Hornet.

is the 160gr. still a more common coice in the 7X57? i figure with the quality of bullets now and deer and pigs generally not being to extreme of animal that the 140's would be fine. I'm actually not sure which weight would be best all around. I am one who leans towards heavy slow rounds.

Absolutely the 140 in a premium bullet would be fine on smaller species and the bigger ones too. The 160 is merely I'd prefer for larger game - just a personal choice since you mentioned 2,700fps.

Given a free loading range, I'd choose a TSX or TTSX in 130 or 140 and drive it at 2,940fps or maybe over 3,000fps for the lighter one. Again a personal choice - not needed, but I merely prefer it. Mucho fun!, but then perhaps those longer range circumstances don't occur where you hail from.

I really like the 160gn Woodleigh and in my rifle 46gn ADI 2209 - H4350 gets it away at 2700fps so it has both weight and momentum for the bullet to do its work with ease, and at 2700 it carries well.

I agree with Daryl, 160's at 2700fps work very well unless you want to flatten out the trajectory a bit of course? And you are right, the premium bullets available now mean you can go lighter if you like (just to confuse the issue)

I have shot a 7x57 for years and killed many hundreds animals with the cartridge.While I have not done tests on all the 140 grain loads I would strongly recommend using the 154gr Hornady and larger bullets on big game.173 grain loads are king in Afrika with the 160's catching on fast.I have done a lot of ballistic tests with various 140 grain bullets and in my opinion are worthless on anything but varmints.I refuse to use a 140 on big game because of this.A Hornady 154 interlock is a superbly designed bullet and holds together and penetrates much better than any 140 ever made.In the 7mm class of cartridges from 7mm Mags to the 7mm/08 the only time I have seen bullet failure is when a 140 grain or smaller bullet is being used.

In a modern rifle why would it not be loaded (handloaded) to the same 55,000cup/60,000psi of its companions of say a .270win or any of the mags. A rem. 700 is a 700 is a 700. They do not use a weaker action for the 7mmMauser chambering. All of this is to say, that the published load data for the 7x57 is pedestrian, near pathetic. It has more case capacity than the cartridge it is always compared to (7mm-08) and will surely bare down hard on 3000fps (pending barrel length) with a 140gr bullet.

Our "family" Ruger 77 in 7x57 has a mile of leade along with a barrel that fouls like no other. The old go-to in this was the 150gr Rem PSPCL with 48grs imr4350 for 2750. Very accurate and has claimed one bull Elk in my Brothers hands, along with numerous deer. My Brother wants a exit wound, so has experimented with a few 160's and is using the tried and true Nosler with a above published load of imr4831 for 2800ish.

Tward, most any of the tougher conventional bullets of 139-160gr will work fine at your desire of 2700fps. Remember Rigby's .275 H.V. was a really shitty 140gr bullet at a listed 2750 in a 28" barrel.

They make bullets other than 173 grain round noses?

Myself I would choose a 140 gr perhaps a Nosler Partition or similar constructed bullet, in the 7x57.

Whitetail are not that heavy a deer species and hogs too depending on how big and tough they are where you are. A 140 gr should still kill however and give a flatter trajectory. Otherwise something in 150 or 154 gr.

I would go for the 160 to 175 gr projectiles for larger species.

thank you all for the input i believe i will regulate the irons for the 160gr. bullets and keep load data for that round then shoot 140gr pills ad deer and pigs we have quite a few here in texas with some big ones thrown in the mix quite often

I`ve used the 170 grains Norma Oryx in my 7*57r with good results on everything from moose and downwards, a bit nasty with the foxes though.

Another vote for a heavy 170 or even 177gr bullet if you happen to have Brenneke TIG or RWS ID bullet at hand giv ethem y try - I do hunt (and track wounded game) mainly in forrested areas where distance is limited to 150 m max. Range from roe calves to brown bears.

P.S. here is a 177gr TIG from a boar

RWS 173 and the Lapua 173 are both most excellent rounds for heavy game.The Sellier and Bellot 173 cutted edge "H" mantle bullet (a RWS copy) is also highly recommended.I am down to only a couple of hundred rounds of the RWS but have a couple of cases of the discontinued Lapua...more than enough for my lifetime.All work exceedingly well on game and are accurate also

I used 139gr Hornady spire points in my 7x57 with IMR4320 powder and doing 2860fps without getting too carried away (early factory ammo for the 7mm-08 also used these same Hornady 139gr bullets). With the same powder load I found the 145gr Speers also an excellent killer. Used both these loads on good sized red deer and chamois and had excellent results. Some 175gr WW factory loads I tried did not kill anywhere near as instant as did the lighter faster slugs with which I had no problems getting good penetration and fast kill.

I never did try out any heavier bullets in 7x57 reloads but used a tonne of 160gr Sierra SBT in my 7x61 at 3000fps and this load could not be faulted on reds, chamois, tahr, whitetails and fallow at any range.

As I have oft quoted, the incorrigible Jack O'Connor's wife used a 7x57 with 160 Sierra SBT doing 2700fps to take 17 head of plains game in Africa with 19 cartridges. Apparently she heart shot a kudu and then used two more shots to drop it to prevent having to follow it too far. Everything else were one shot kills. That's a pretty good testimony to the old timer cartridge and the Sierra bullet. I don't use any other brand of bullet in any of my present and past guns other than my 404 which of course Sierra doesn't make bullets for.
Another example was my hunting friend using his 7x57 on Aussie buffalo with some loads I prepared for him using 160gr Nosler Partitions.

My #1A in 7x57 had only a 22" bl. It made lovely little groups with 140gr Nosler Partitions driven by a decent load of IMR4320 - 2,940fps. The fellow I sold it to used it as his main hunting rifle for a number of years, shooting 1 or more deer and 2 black bears with it, each year. He used the same load.
A modern 7x57 Mauser rifle will duplicate or exceed the same barrel length 7mm08. The '08 case has a better shape, the 7x57 a couple gr. more capacity. They are pretty much dead even with the lighter bullets. Sometimes magazine restrictions hurt the performance of the 7mm08 with heavier bullets.

CIP specs for the 7x57 Mauser is 57,000PSI - same as the 8x57 and 9.3x62.

I'm building a rifle on a VZ-24 action in the classic british style. It'll have a 22" or 24" barrel on it, I'm not yet decided on that part yet. This will replace my current push feed model 70 in 300WSM

I had my 7x57 (built by Clayton Nelson)specifically to shoot 175gr Nosler Partitions in Africa. It shoots them beautifully and when I used it in Africa it had absolutely no problems taking Kudu at ranges out to 275 yards. Lessr game such as Impala were also no problems either.

zimhunter,

That is great to hear; thank you for sharing those examples. Too often people are under the impression that the heavier for caliber projectiles at moderate velocities can only be used under 150 yards. We chamber our rifles with custom reamers specifically for the heavier for calibers projectiles in the various 6.5mm's(160 grn), 7x57mm (173-175 grn), .303 (215 grn), and others. We also ensure we use the appropriate twist rate for the heavier projectiles.

My custom 7x57 has a long throat and shoots heavier projectiles more accurately. I have used a 140 Sierra at 2,700fps but that is not what the 7x57 is about.

Currently useing the 173 H-Mantle for camels but when they run out the 154 Hornady (Spt or RN) will be the only projectile I will use.

My Ruger No.1 (22" Barrel) loves 154 grain Hornadys at 2640 fps, either SP or RN. These shoot more than well enough, like an inch or a bit less, depending on how well I can hold it, and they kill fallow deer with no fuss at all.

It also likes the 160 grain Woodleighs, shoots them into the same size group albeit to a different point of impact. I have not shot much game with these yet, but so far they perform like Woodleighs do, excellent.

Best

Exit wounds from 140 grain Barnes Triple Shocks at just over 300 yards (shooting down hill into a ravine) from a custom Mauser in 7x57. The first shot would likely have done the trick as the kudu was wobbly on his legs. Took two more for good measure.
