i had a left renegade .50 percussion with QLS(?). on the advise of this forum, i sent it to robert hoyt to be bored to .62/20ga smooth bore. i couldnt be happier or more impressed. i sent the stripped down barrel apox 3/6/2019 and got it back yesterday 4/8/2019. i called him had a very brief conversation to get the price. i sent a check with the barrel. in the very secure package was refund money because i had sent too much. he could have kept it, i wouldnt have known. the barrel looks great. mr hoyt WILL get any future work from me. an skilled and honest craftsmen!!! a rare breed. thank you sir!! irishtoo
