Thank you for your opinions and suggestions. The 1895 isn't going to win any beauty contests that's for sure. I stuck one of the filler blocks in the dovetail and there is a lotta light underneath the block. I think the story about the bore expanding from excessive heat came about when guys starting to sporterize mil surps and fried the solder under the rear sight base causing the changes in bore dimensions. Tig welding is very localized so I don't think there should be any problems. Thanks again. Frank
