Re: 7mm rem mag velocity

I have both the 7mm RM and the 7 WSM and the only time the WSM comes close or even with the
7 RM is with the 140 to 150 grain bullets. the 7 RM has an edge with the larger bullets.

Elk At 600+ yards is asking a lot of the 7mm Mag and second shots are to be expected.

This is the distance that a big 30 comes into its own and the 338s are even better.

Re: 7mm rem mag velocity

I agree that's a lot of distance for a 7mm. Two years ago I shot an elk ranged at 528yrds. Two holes, one in the vitals where I aimed. He laid down 10 feet away and I planted another in the neck. He was angled away from me and the bullet went a little higher than I expected. Once I dug the bullets out it was clear that the 160 game kings were not exploding like they do at 350 and 400 yrds. They both seemed to stay together more than I had seen before. I have never shot any thing lighter than 160's except 100 rounds of 100gr varmit I shot whistle pigs with. After that elk and the one I lost I have decided to go heavier. I do not know personally how the 175 sierra will knock down an elk or a berger 180. I hope they get the job done quickly as I hate tracking wounded elk. My brother in law keeps me in good practice with tracking.

Back to my original question....any one have input as to the slow velocities the shilen barrel is producing? The gun smith I have decided on claims this barrel can be saved, I am not convinced. Any one gonna tip me over on keeping it or pursue the lilja barrel?

Re: 7mm rem mag velocity

speed wize your wsm may come close to the 7rem but will never pass it. Problem with pushing either so hard is your going to reduce barrel life and brass life will be non existant. If you truely need more then standard 7mag level loads look at a 7stw or a 7 ultra.

Re: 7mm rem mag velocity

This is just my 2cts! I've shot a 7 mm mag for a little over 30 yrs, I know an understand that every barrel an rifle, etc are differant. That being said, back 20 plus yrs ago the load I used in my 7 mag(24in barrel) was 64gr IMR 4350 cci 250 primer, WW brass. Was gettin about 3020 fps! Another load I'm using today is 71gr of H-1000, both loads are with a 160 grn Gamekings. Been shooting the 168 Bergers with the same load. I've never took the Gamekings over 600 yards but they do work well to that distance I know! If it was me( an everybody is differant ) from what I've been reading I think you have your heart set on a new barrel! If so make sure that you have confidence in your smith an feel comfortable with the decision you make! The 7 stw is a good round, the 7/300 win mag is also a good one too! Hope this helps, just my 2cts!

Re: 7mm rem mag velocity

I have done a lot of loading for and hunting with the 7 RM, and you should be able to easily get 3000 fps with a 160 bullet out of a 24" bbl let alone a 26" bbl. You're freebore is on the short side and that will affect your velocity so re-reaming it may increase velocity, but... 4" groups would make me very leary. A good custom barrel shouldn't be very picky. Sometimes you get a bad one. I used 4831 with my 7mm and it worked well. If I were to load again for one I would try Retumbo and RL17.

As for what cartridge to use for elk, a 7mm at LR is pushing the envelope a little and requires good placement. I would prefer a 300 mag of some sort.
