Ron,
Thanks for the info... I do have a 45 fast twist FM...not sure it is 1:30 or not... I picked it up in Friendship about 12 years ago and put together a caplock from parts gleaned during the shoot...intended it for my grandson... but looks like he isn't going to be a shooter or hunter... everyone around here seems to only want 50's...I have 3 45's and 2 50's now as I have begun to get rid of some of the guns in the safe that I don't use.
