I finally found out (i think)
Ok.. So my lyman .54 "trade rifle" is actually a lyman plains rifle, not the great plains rifle. I've had so many conflicting ideas on what it was. My dad bought it off a private seller in the 90's who didn't know the exact model. He just said it was a lyman.
I've had people tell me at the range it was a trade rifle, then i'd have other people tell me it was a GPR. I tried multiple times to do research on it and find out what exact model it was. It looked like a trade rifle except for the brass on the stock, which holds cleaning gear.
Today i decided to try to find more about it. I found a forum where someone posted a pic to help identify it. Everyone said it was a plains rifle. It was before the GPR and is now discontinued they said. I can't find hardly any specs on it. I would like to know the twist rate on it. I've been shooting PRB (90 gr 2f goex) out of it and it will hold baseball size groups at 50.
