Hello everyone, been on the forum getting great advice and info! Original problem was talking about chambering but no luck. Also, talking about various supplies to get to what I had in mind. The subject came up about my Bull bbl. In 45-100 about it might be a PPB chamber (I thought it was) but my letter and under the bbl. there is NO stamping as such S/N 54xxB. So, I was informed that the Bull bbls. are tighter than .450/.458? but no spec was mentioned. Anyone know what the Bull bbl. specs are? Also, rear dovetail specs? I do want to say I've been getting alot of help from the members on here and I greatly appreciate they're efforts😁! I did email, msg. call but haven't heard back yet.

I wonder if the same is true for the 50 calibers?

Hi bohemianway, could be a difference of a .001 like the .45. He mentioned the Bull bbs. don't react like the regular bbls. do or something like that? :? Very intresting conversation and informative about tech stuff! Stay Safe! Rich
