Deciding on a 7mm. 7mm rem mag/ 7mm wsm

[Patton243]

7 SAUM or 284 Winchester gets my vote. These would be your most efficient and potentially most accurate cartridges for the 7mm. Since you already have a 7 mag bolt face I would go 7 SAUM then. That's exactly what I did after my 7 rem mag barrel got about 1000 rounds through it and I have no regrets. A bunch of companies make 7 Saum brass now including ADG, Gunwerks, Nosler, Norma, and Peterson has intentions of making it in the future too. I have the Gunwerks brass. The 7 SAUM will get better barrel life than a 7 rem mag or any of those other big 7 magnums. I would stay away from the 7 WSM too. The case has a rather short neck and pretty much failed as a competition cartridge over the 7 SAUM. Good luck.

I think it is a combination. Yes, it will handle more pressure (a good thing) and yes its more efficient with a shorter burn column and a sharper shoulder and less body taper (also a good thing)
the worst thing about the wsm is the neck is too short! And ya I know they have shot well but they would be better with a longer neck and would help cut down throat erosion too.

a forgotten caliber the 7mm stw...

Why hasn't anyone mentioned the 7mm weatherby? Out performs the rem mag and wsm.

I've also heard the 7PRC is coming.

What are you saum guys seeing for velocities with the 180s? Mainly the 180 eld. My planned powder to run is rl-26. That's what I'm currently using.

You already have all the stuff for the 7mm mag? If so I would say stick with it. If you're wanting more umph, but less barrel life the 7 STW, 28 Nosler and 7mm lrm would give you more velocity.
However if you're setup for 7 mag I would stick with it. Get a custom barrel built for the bullet you want and you're good.

Ya I'm set up for 7mm mag sorta. Really the only difference is the dies and I planned on buying new dies anyway. Still running an old set of rcbs dies that ny dad bought probably near 20 years ago. I basically want an efficient case that runs me a 180 class to 2950+. I dont really want a nosler or a stw.

7 mag bud!

7 mag bud!

Lol its definitely hard to get away from that round! It's an oldie but its sure dang hard to beat. I was just wanting to be different and more efficient.

I will never be without a 7mm Mag. Just have a custom barrel installed and you good for as far as you can see with practice. My question is always. Will I see any advantage in a extra 1-150 fps that cant be overcome by practice? I think the biggest advantage is learning to read the conditions, practice real field shooting positions and loading the best loads you can. And there is never a shortage of 7 rem Mag components

7mm Rem Mag no doubt

 

[carl1775]

Hard to beat a custom 7 Rem Mag, that'll push factory box ammo into tiny holes and crush hand loads. My favorite, but I'm biased.

Well, I vote for the 7 rem if you want to stay around 2800-2900 for a 175-180 bullet... I would also go with a 8 or 8.5" twist. If you want 3K + fps on the heavies, you are going to have to go 7stw, 7rum, or 28 nos (7roy I suppose too if you like round shoulders). You just can't get around the fact that the lesser 7mm's will be run over pressure to get a lot of speed with a 175.

I just picked up a Tikka t3x in 7rem for my boys to shoot. I plan on the rifle being a garbage can; I have a lot of oddball powder and a couple thousand mid weight 7mm bullets for it to eat. It's only got a 9.5" twist so it's perfect for this (my 7stw and 7rum wear 8" twist barrels).
