Well Semisane...I hope you have good luck with your Lyman GPR. My wife bought me one for Xmas 6yrs. ago andupon its debut at the range (which was my backyard) I had problems with it going off. I would load the gun at the table, prime it, walk over to my shooting chair and bench it. I thoughtI was getting a little"senile" at first, but upon closer inspection I discovered that the stock was not inletted deep enough from the factory and the lock was.040-.050thousandths from butting against the barrel. In the short distance that I walked from the loadtable to the shooting bench after priming the lock...the priming powder would sift down behind the lock leaving the pan empty. It was probably just a fluke, but I took it back to the dealer and swapped it for a T/C PA Hunter in 1/66 twist and have notbeen dissapointed in that....BPS
