Bat MB 300 WSM???

[Phil]

Would my MB action be a good start for a 300 WSM build???

I have a BAT M, which has the same port and it is in .300WSM shooting 230gr Bergers in F-Open. I can pull a round out, if necessary, without pulling the bolt out. My freebore is .280.

Does it have a Mag boltface? New Bat bolts aren’t cheap.

I’ve been running my 300wsm on a MB for years w/o a hiccup.

I think the M has a slightly longer port than MB..

Also running a 300WSM on a Bat MB with no issues. I do have to remove the bolt to pull a loaded round but it isn't a problem and rarely happens.
