That is REALLY COOL that your boy is interested in this stuff! Sadly, Not many kids are these days. Back when i was a little kid 9 out of 10 of us boys in school hunted, Now days maybe 1 or 2 out of 10, These kids are the future of Hunting, if it keeps going the way it is, it will be easy for the Anti's to do away with it, no one will care, or even argue it.
The little CVA rifle you bought your boy is a REALLY NICE lookin little gun!! I have never owned a CVA, i Have been a die hard Thompson Center fan, The Hawken and Renegade are my absolute favorite Stocks, do away with the stock barrel and drop a Green Mountain LRH in its place, in my opinion that's about as good as it gets! I have not had any luck with stock 1:48 twist TC barrels, matter of fact i have learned to hate them! I think i expect to much from them? When you get use to shooting 1" Groups CONSISTENTLY at 100 yards with these fast twist GM barrels and the right paper patched bullet, it's tough to grab a stock 1:48 Twist and accept pie plate Groups, My experience with MANY Stock TC 1:48 Twist barrels is they DO NOT LIKE undersized paper patched bullets, That being said, a good friend of mine asked if i would teach him how to clean a Muzzleloader? He inherited it from his Grandfather, it was an old CVA .50 Cal Hawken and had been badly neglected from not cleaning properly, I Scrubbed and Scrubbed on that old rifle, pulled the lock apart, triggers, Gave everything a SERIOUS going over. We took that old rifle down to the sand pit and tried a half dozen or so of my Paper Patched S&W 500 bullets, that old CVA Hawken came ALIVE! My friend stuffed 3-4 of them inside 1" at 50 Yards, then broke clay pigeons on the bank with the last few, This was a Stock 1:48 Twist rifle.
