7 mm SHERMAN SHORTMAG vs 7 SAUM

[CA48]

They are the same case. The SS has a 40* shoulder and the SST has a 30* shoulder, which comes out to a ~50fps velocity difference. I have the same opinion as Phil. Since you're going up to a XM plus action you could move up to the 7max. You could always run it at 7SS speeds and get better Bbl and brass life.

You would benefit from the longer FB option with the 190 LRHT I'd think.?

Thanks for the assistance. Much appreciated. Checking out 7 Max now.

Mr Rich is the one to advise, and is always willing and helpful. Good luck and keep us posted! Looks like a very effective combo you are assembling.

The more I look at these, the more undecided I am. Comparing 153.5gr LRHT Bergers for 6.5Max and 190gr LRHT for 7Max. I put in a call to Sherman and left a vmail, hopefully his return call will clarify things.

Interesting! Started breaking in a 6.5 max this last weeekend.

That looks good. Rich called me back and I'm sticking with the 7 Max and 190gr Bergers to start with.

At the distance youre talking about heavier would seem better to Me

By heavier I meant the 190 over the 153.
Good luck!
