I'm considering re barreling a 110 (long action) to 45-90 or 45-100.

OK, when ya'll stop laughing, would someone help me select the proper bolt head and any other parts I might need to do this?

It's amazing how many crazy thoughts have run barefoot thru my mind, after I stumbled across a 32 inch, .45 cal. heavy octagon barrel, 1:22 twist...
