They are great. I have two, one in hte .54 and one in .50 cal. The .54 cal has a 1 in 24" twist and loves to shoot sabots. I am shooting a Barnes sabot and have harvested deer with it.

My other gun has a 1 in 66" twist and I shoot PRBs in it. I paid $400 for the .54 cal. Cabelas rifle and yours would be a great price.
