I do not use powerbelts but all ammo has jumped. I bought 2 boxes X18 of the Knight (Barnes) Poly tipped for $17.95 the week after Christmas. They are now $ 23.95 a friend says. I am going hunting this weekend in Alabama and there is a very good sporting goods store on my way. I called him and he is not raising his prices until he starts paying more for his. He is saving me 6 boxes of the Knight bullets and 10 boxes of 17HMR. Great people.
