60` V thread, UN 20tpi. 1.055" or 1.120" depending on shank size. LRPV, normally WSMs, normally RUMs, F Class actions are large shanks. The F/TRs and precision target actions are large shank too.
I should add, Savage likes to clean up the shelves so nothing is a given, you need to check the shank sizes and now the bolt heads can be different.
