Bertram has 6.5 wsm brass
7wsm has more case. Slightly shorter neck6.5 wsm a med length action would be the ideal thing if i was starting from scratch ona build , i all ready have two short actions in use for wsm cal ,so i just run the 140 gr bergers and the OAL works with an extended mag box .
3200 fps with 140 your really not giving up anything to the newer heavier class bullets .
i have tried running a 150 class bullets and the velocities were slower ,so time of flight effected wind dope in a negative light out to my max hunting range .
if your planning to run 150 class bullet the med action would be my choice.
also if your looking for the 7wsm
make sure your smith has a reamer base off a 300 wsm case design if you want the most case capacity .
the factory 7mm wsm case is a lil different and was designed that way as not to be able to chamber in another 7mm short mag chamber , i beleive it was the rem ultra mag but im going off my memory.
the factory 7wsm case has a little less case capacity .
for that reason my first was the 270 wsm chamber .
What Brass do you use to neck down to 25WSM?I have 2, a 300 and 25WSM and I really really like them
