Mtnman:
Thanks for the info. But I'm still not clear. Here is what he said:
" This is what I'm thinking so far...I have a TC Encore muzzle loader. I found a place that chambers for 375 H&H or even 375WSM or several other 375 standard or wildcats...Including the 376 Styer. The place is call Virgin Valley Custom "
That specifically implies a muzzle loader.
This is apparently what YOU are talking about :
http://www.tcarms.com/catalog/pg15_cat31.jpg.phpThis is referred to as a T/C System.
There is the T/C System 1 in line rifle, interchangeable barrels. And there is the Thompson/Center Encore 209x50 Magnum with interchangeabe barrels.
For my participation it is always necessary to be very specific about everything.
For example when someone tells me they have a Winchester muzzle loader that they want to chamber for a centerfire rifle breech loader I understand it as a rifle that loads from the muzzle.
As a matter of fact Fred Hall, gunsmith, conversely specialized in converting centerfire, breech loading bolt actions, and lever action guns into muzzle loading weapons.
