| 150gr. Bullets in a 22" BBL. 7X57mm-What velocities? | Login/Join |
| One of Us |
I recently bought a 7X57 in a Rem.700 Mountain Rifle. I am loading 150gr. Rem. Corelokts with 42.5 gr. IMR 4320 and getting 2650fps. Was wondering what velocities anyone else is getting with a 22" bbl. and 150/154gr. bullets? Also what kind of terminal performance can be expected with the 150's at that velocity on deer, elk, hogs? I will probably load up Nosler Paritions for the elk hunt.

well, I don't have one but quick bit of research showed that's where the manuals say you should be... 2650 fps is just about perfect for cup and core bullets as well as nosler partitions...shoot that elk or pig through both lungs and they will die... and any bullet is a good deer bullet Mike Legistine actu quod scripsi? Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.  What I have learned on AR, since 2001: 1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken. 2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps. 3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges. 4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down. 5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine. 6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle. 7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions. 8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA. 9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not. 10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact. 11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores. 12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence. 13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances. | |||

I hunt with one, and the MV you are getting will tackle about anything you want in the lower 48... that is a nice rifle...so enjoy it and go bring home some venison... | |||

You are good to go on all three. I shoot 160gr TSX's at 2600 out of my 22" gun and would not hesitate to shoot anything in the lower 48 or African p.g. Perry | |||

i'm only pushing 140's about 2650 in my 7x57 improved and they never failed to drop a deer on the spot when the shot is right. you shouldn't have any problems at any reasonable range. i've been using a 7x57 improved as my main deer gun for at least 20 years. it's a G33/40 with a 23.5" douglas. i know i can get allot more velocity out of it if i want to, but what for. my latest batch of cases have 11 loads on them and the primers are still tight enough....39 gr. of 4064 and a 215 primer. i'm one of those who use the ackley for it's originaly intended advantage....case life. the 7x57 is one of those rounds that doesn't really need any help to do it all. | |||

Rae..I load my wife's 7x57 (it has a 24" barrel) with 140gr bullets running at 2735fps and she has piled up deer, antelope and hogs. She thinks that rifle is magic!! The bullets she uses are Hornady SST's and interlocks, Nolser BTs and partitions. I suspect that your load at 2650 will work just fine with about any bullet you use. Z | |||

I agree that your load is good. If you want a little more of a boost try H-414. I put 50 grains behind a 140 grain balistic tip and get about 2900 and real good groups. ...tj3006 freedom1st | |||

I shoot a Final Finished fire-lapped ( might increase velocity a tich)Ruger M77 tang safety with Win cases, Rem 9 1/2 primers, and 46.0 or 45.5 (can't remember which exactly now) grains of IMR 4320 with Sierra pro-Hunter 140 gr's. I get upper 2800's that bumps to 2900 sometimes. You aren't far off the right velocity for your load. You could up it some but at 150 grains, you might want to opt for a slower powder such as 4350. 44 grains might not be an insane load, just thinking off the top of my head. I know the Lyman book has my load maxing-out at 45 grains and like 2900fps, but that's at the 46,000 psi limit designed to protect old rolling-block actions. Well, my 308 has pressures near 60k PSI. Does brass or copper or Cro-Moly steel know one cartridge from another? Can it tell a new round like the 7-08 or the 260 Rem from the 7Mauser or the 6.5 Sweede chambered in a Rem 700? That exact rifle shoots 7 Mags with only a bigger bolt face and slightly longer action. If you exercised your freedom and aren't in jail, thank a liberal. | |||

I can get higher velocities with 4350 and 4064 but the groups are not as good as with IMR 4320.

mine doesn'r seem to like the faster stuff as much. any faster than 4064 and thing open up more than i like. i don't need to have a 1/2" gun, but i've tried some loads with 3130 that weren't any better than 2-3 inches.... i don't need that, either. never tried 4320 and oddly, i haven't tried any H414 yet either. | |||

Rae: FYI. My notes indicate that 10 rounds of Norma 150 gr. factory loads that I chronographed in '97 from my M700 MR averaged 2662 fps at 15'. Cheers, Al | |||

49 grains of IMR-4350 with either 150 NP or 154 Hornady SP runs 2726 fps and kills elk quickly. | |||

I have had the same results: velocity between 2700 and 2750 fs in my 7x57 with WW brass, 49 gr IMR 4350, 154 Hornady and a variety 160 grs bullets. The rifle has long magazine and long throat as well. PH | |||
