Thread: Tikka Extraction/ejection

Hey Folks

Has anyone tried or know if a T3 equiped with a bolt with a .473 boltface will reliably feed, extract and eject rounds with a .378 base (or can be modified to do so)??

Thanks

PS Please note that I'm NOT asking about the validity or otherwise of the idea, just "does it function".

I wouldn't think so.
0.473" = 12.0142mm, and .378" = 9.6mm - so a difference of about 2.4mm which is quite a bit.
I cant comment with any actual experience on this, but 2.4mm of slop on a bolt face, imo, would create extraction issues.

Thanks Chris, of-course its only 1/2 the 2.4mm but . . . my local GC was good enough to try a .473 bolt in a 223 and while it fed fine, it wouldn't extract, the claw can't get far enough across to grab it, so would need gunsmithing to make it work. I'm not keen to invest that much work (and risk) in a Tikka . . . .
