Hi All,

I have an old M77 MkII All Weather in the boat paddle stock that I believe was originally a .223 then rechambered to 22-250 and the bolt face opened up. I'd like to rebarrel the rifle to something based on the 308 cartridge, but the mag box is only approx. 2.3" long, and the bolt does not come back far enough to allow longer cartridges to feed from the box either. Other than a 308 mag box, what parts or modifications do I need to fully convert this action to accept 308 based cartridges?

Thanks for any insights and God bless!

Adam
