i have a traditions inline Buckhunter and with the 240 grain hornady sabot and 100 grains of Clean Shot, it doesnt kick hardly at all. not even close to my .243.
btw guys, check out the clean shot. it is less flammable than black powder, and- i am not kidding or exaggerating- takes 3 patches to totally clean your gun. one to push the gunk out, one to touch it up, one to oil it. youre done.
amazing and worth the money to me. in fact it has led to me using my muzzleloader more.
