I have reamers for all 3 but the only rifle is a 35 Whelen. I doubt I'll ever build myself either of the other two just because I don't feel the urge. I had built a 35 Whelen, based on a 98 Mauser, in the early '80's. It came out pretty good and I decided I should have one like it; so, I built another for myself. I still like it. GD
