I have a knight wolverine that will drive tacks. It shoots a ragged hole at 100 yards with 80 grains of 777 fffg and a 220 grain Dead Center sabot. I still use the #11 primers with it. It will outshoot my encore (by a little).
For your application, I especially like the double safety for a young hunter.
I have also found that Knight has very good customer service. I don't have any personal experience with CVA, but I have heard that their customer service is not that great.
You may can find a good deal on a used (or new) wolverine with the adult stock and then purchase the youth stock for about $75 I think.
Hope this helps,
Smoky
