Barrel life should be around 2000-2500 rounds, i am building one right now on a savage LA, the mag is long enough that i will be able to seat the 195 berger when it comes out so that the shank/boattail junction is above the neck/shoulder junction of the case and still be able to feed from the mag. Ive done a ton of research on this cartridge and feel that i know quite a bit about it so if you have any other questions go ahead and ask.
