Bull bbl. Bore/Chamber specs and rear Dove Tail Spec.

[BlackJack]

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
