I am surprised that you can get 3040 fps from a 180 grain bullet from the 7WSM. My brother has a 300 WSM and gets in the high 2900 to low 3000 fps range. I shoot a 300 Win Mag and can get over 3100 if I push it but again it is quite surprising to me you can get that velocity. What powder do you use? How many times can you reload the ammo before the primer pockets are too stretched to hold a primer? Thanks, Rufous.

Wasn't really to much of a problem.  Of all the ones I have built for guys, the lowest was 2980 with the 180.  My chamber is designed a little differently and Broughton's are generally a little faster.  Have verified it out to 1600yds this last weekend and its spot on.  I use H1000 and Federal 215M primers.  So far I have 7 firings on the same cases (30) I have been using to break it in and range test and the primer pockets are still fine.

His barrel length being 26 inches too adds another 100 fps.. On a short action that is a long barrel.

That is a gorgeous build right there Travis! You guys are putting together some of the best looking tactical and hunting rigs I've seen in some time.  Not to mention the fact that you shot a 4" group at 1K! That alone blows my perception of what a hunting rifle is capable of..... what kind of barrel life expectancy are getting from the 7WSM?

Getting over 3000fps out of this gun should be NOOO problem.  I shoot a A-bolt Micro Hunter II 300WSM 180 grn Serria Pro hunter bullet 64 gr 4350 and easily get 3100 fps out of it.  That is verified through the chrono, so your brother should be getting better than 2900 if he wanted to.

I have a couple guys that have close to 1700 rounds down theirs and they are still shooting under 1/2moa.

I think I have a 25-06 SS sporter barrel.  I will check later and let ya know.  If its still there, its brand new and never fired.
