There are some guys on the site that really like the CVA Wolf and if I remember right its about the same price. As for the Impact, the only thing that I don't like about it is the breech plug. It doesn't have to the nice one that the Triumph has. However I think the Wolf has one like the Triumph. Every gun has it's pros and cons. One of the biggest thing is the fit of the gun. Have your son put them up to his shoulder and see what fits the best. Also the CVA Accura is on sale thru Midway for almost half off. That would be a great deal. That would be a muzzleloader that would last his lifetime. I have the Triumph Bone Collector and love that gun. Sometimes if you watch GunBroker, you can get that muzzleloader for 100 dollars off.
