I appreciate the replies very much. Looks like I've got a lot to learn and, thanks to you all, I'm on my way. It would be nice if Mr. Seyfried would put all his articles in one book. I wrote him recently about a 375 flanged 2 1/2" rifle I have and he wrote me right back and was very helpful - a classy guy!
