What primer for the 7 saum Mag or large rifle

 

[Preacher]

I use the Federal 210 M's in all my 6.5 & 7MM SAUM's with out a problem with H-1000.....
Never felt the need for a mag primer in them.....

Thanks Preacher

Now if I was going to run those guns in extreme cold conditions, I would use a mag primer I suppose....
They all shoot so good as they are, I hate to try anything else..

OP-- Just as a way to prove things "fur sure" load two sets of 10 shells 10 with standard primers and 10 with magnum primers. Shoot them at a target at least 200 yards away. Compare group sizes, record the mean velocity and sigma of each group. That should give you a real answer.
