First one in 1967 or 68. Have had about eight over the years. Now, only three, one the last model before the G2 plus two carbines. Calibers: 22lr (dead nuts accurate from pistol or rifle), 222(still working on this old octagon 10 incher), 30-30(one 10", one 21" long one great, short one not so much), 357(like all I've had, super accurate and hard to lead), 44mag (dumb short hot shot thing), 45 Colt(octabon 10", my deer gun), 45/410 bull (used to be fun but the Colt part is useless with anything above factory speed), 223 in a carbnie barrel...getting MOA with some loads.
Addictive, and not too expensive if you watch the shops for used barrels. Most I've paid less than a C-note.
