RE: Ruger 10/22 Question
Like stated above, the 10/22 has a huge aftermarket. That's why I have two. Paid $179 for a new one and $165 for a used CRR (youth) model. Both now have bull barrels. One wears a hogue overmold stock and the other a thumbhole laminate stock. Both trigger groups have been worked over with aftermarket parts as well.
I really don't think you can go wrong with either, I just like to tinker.
As far as your other question. Everything is going up that has to do with guns or ammo. Supply and demand right now. Everyone is fearing the worst based on the president elects past voting record when it comes to taking away our right to keep and bear arms. This following the high demand for metal in China is the big reasons. Not sure about the muzzleloaders not going up. I did hear a good story about some lib wanting them banned as well. You know how dangerous those .50 cal anti aircraft guns are.....
