26" mcgowen large shank, bull
winnie case, cci200, 48.5 varget, 110vmax, 2.700, jumpin alot, no way to getem near the lands. 3150ish ES 25, SD 12. funny, my sierra 110hps are 125 fps faster w the same load, and have better ES/SD...but they fall apart at distance quicker. both shoot fine groups. this particular barrel is the only one i currently own that couldnt give a hoot if im close to the lands. makes life ez. btw, i have a moderate Lee factory crimp onem...they function fine and shoot well though my m1a as well

GL!

like to hear how they work for u as well
