how about the sabots that hold roundballs?? theres alot of options...i dont know what a rb would do in a fast twist barrel?...be more accurate because it has more spin? or have to much spin and spin off wildly? i agree though a patch and ball kicks alot less then a big ole bullet.....i cant wait to get whacked with the recoil from a 350gr maxi soon.....brass buttplate and all....i could handle 295gr powerbelts though....im built for recoil.....theres alot of options for light recoil in the ML but dont know what will work best out of your guns being i have a 1:48twist flinter.....good luck
