Now there's a little sumpin a fella can take to the Bank.
RM...I guess I'm a bit surprised you are having problems with your flinter.
The Lyman GPR rifle is, and always has been, one of the most respectable, most dependable, out of the box rifles the common man has had readily available.
On par with anything, and often far above most.
Having owned and often shot no less than three of those rifles over the years myself, I can say that with some confidence.
Currently I am GPR'less, and of all the rifles I have owned, sold, traded, or just flat-out given away, the GPR is the one I look most forward to owning again.
I do hope you get whatever problem you're having worked out, and you get some enjoyment out of that rifle!
There is some powerful good advice right here in this thread, and, FWIW, I personally know you are no rookie, not stupid, and you do enjoy a well functioning rifle as much as the next guy.
You might want to look around for those little Angels that prairie dog spoke of...it's not that they're evil, just a bit mischievous.
Once ya got things worked out, you'll think they are working with you and for you, and that is how it should be with a good flinter.
Good luck bud!
