My Remington 700Ml (1/28" twist)shoots roundballs very accurately at 50 yds.I use Hornady swaged round balls with.018 pillow ticking,50 gr.777,and either remington #11 caps or WW 777 209 primers.It will shoot into 1.5" at 50 yds.My gun shoots to the same point of aim with this load that it does with 200 gr Shockwave,100 gr.777,WW 777 209 primer at 100 yards.SoI don't even have to change my scope zero.I use the roundballs for cheap,low recoil practice.
