A few years ago I set up a Tikka 300 WSM for LR hunting. It is a factory action and barrel, CDI dbm, fed by .338 AICS mags from the factory stock. I originally set it up to touch the lands or jump a couple thousandths but I don't want to chase them and I don't like the massive .338 mag. I am going to put it in an Elite Hunter stock and I want to refit the DBM and mag situation. Will 300 WSM feed from 308 AICS mags? They fit in my 308 mag but I'm unsure how feeding into the Tikka action will work. Any DBM recommendations? Thanks.
