Doc W's 7RM was 20" and very nice indeed. I probably should have bought it when I had the chance

My 7RM (bought off DW) is either 20 or 21" barrel and runs Berger 168s at 3050

21.5 any shorter and it gets harder to do the cool stuff

Nah same chrony gave 3060 fps with 71.5gr 2217, 162 amax in my 26" 7mm rem mag. Drops out to 700 - 800 were fine.

Chopped my T3 back to 22" and put a DPT can on, at 24" with the 162 AMax and N560 I was getting 3090 fps, after the chop and can the same load produced 3123 fps ! Not what I was expecting, grouping improved too.

Only other factor that I thought might have influenced this was velocity measured at 24" was at the NZDA range in Upper Hutt, at 22" at the NZDA range Christchurch.

Measured velocity means zip unless its validated

Keeep 7mrm at 24 in get a 7mmo8 for bushpig just my opinion

I was always told speed isnt everything. Seems like everyone want to be up @3000fps

Speed certainly isn't everything, great consistency in accuracy should always be the primary objective, but if you can get near max possible velocity (for your cartridge/rifle package) while keeping that great accuracy then why would you not want the extra advantage from reduced windage and more terminal energy etc/extended useful range?

With suppressing a super short 7mm Rem Mag you need to be wary of the pressure at the muzzle and the effect that will have on the suppressor.
last thing you want to do is wreck your suppressor

Has anyone run factory ammo through shortened 7mm Rem Mags? And if so, what performance are you getting and how is it to shoot?

Dunno about factory ammo but with reloads plenty of people are still getting a 162 at 2950 - 3000fps out of a 20” barrel. I’m intending to chop mine from 24 down to 21 next year.

Don't do it....do what Trooper90 says...or get a short 308....
Just saying...

Already have a short 308 for bush hunting. Just toying with the idea of an all rounder with factory ammo from bush to tops.
