MM/Jason:Off topic, but I checked the Federal Premium factory ammo with 160 NPT in the 7mm WSM. From two rifles (a Kimber Montana and a M70 FW) the stuff gave 3250-3260 in both rifles,along with swollen brass and ejector slot marks.

I contacted Federal; they said the stuffs loaded to 65,000 psi. Well.....maybe smile

Handloads at a bit over 3000 fps shot fine.
