I have a Thompson Center Endeavor muzzle loader that I want to replace the muzzle loader barrel and change the rifle over to a .300 WinMag with a Thompson Center "Pro Hunter" barrel. I am curious if the same barrel that fits the Thompson Center Encore will fit the Endeavor receiver? There seems to be a little confusion about whether the Endeavor is a designated muzzle loader or not. I could use some help here as I cannot seem to get a definitive answer from what I found in my searches. Thank you for any help.
