Thread: 7mm Blaser Magnum info

How do they go on a tikka action? Can you seat close to the lands with a 162/180gr eld’s and still mag feed?

Yep no problem built a few on Tikkas, they just have to be throated accordingly

Is the case efficient enough to handle a shorter barrel (say, 22") I wonder, and do you think it would give a worthwhile margin over the SAUM at that length?

I have a 24" test one on a Tikka that goes unbelievably well so I would say yes.

What are you all seeing with COAL for a 7 Blaser and 180gr (ELD-M and Hybrids) bullets? Any chance this would work in a mid-length action?

running mine 3.265 COL with 180 VLDs. cant see that fitting a mid length action ?

Hello All,
I too have been bitten by the 7mm Blaser bug, I have brass on the way and good stock of berger 7mm match bullets on hand to dummy up some rounds to get an idea of what i want in a reamer but i am leaning towards a min spec chamber with about .230" free bore.
My plan is to first built a heavy long range rifle with a 26-28" barrel then a lighter hunting rifle later on.
Does anyone have real world load data with the 180gr weight bullets loaded with AR2217 and AR2225?

regards Sam

RL26 does look intriguing but there is no freight option to bring the Alliant powders into my state so its availability to me is limited. I also would want to most temp stable combination i can get even if that requires sacrificing a little velocity hence my interest in the ADI powders.

Hi guys, this caliber sounds like the way forward. I am thinking about building one of these and was wanting to know the following from those shooting the 7BM:
Barrel length?
Twist rate?
Projectile weight?
Velocity?
Accuracy?
Thanks, much appreciated.

So far have done them from 24”-27”
All 1:8 twist
All running 180’s
Velocity 3000-3100 accuracy loads with rl26
Accuracy very good so far seems to be a nice well balanced combo,

Any one got a trim length for the 7mm blaser magnum?

24in
8.4 twist
180 VLD or ELDM
RL26
2960 with VLD 3020 with ELDM
Proof carbon Barrel, lone peak Ti action.
Accuracy.
It loves VLD Hunting close to the lands.

Issue is getting brass or paying 350 for 50 cases. and of course RL26. And VLDs. And dies , It’s a pricey game.
