It is not often that I am 100% thrilled with a large HOBBY investment but I am with my Corbin Press and the super great support from there people . The money I save on the price diff between my Corbin slugs and store bought slugs is 1/5 THE COST and I shoot an average of 1500 rds per month . It is what I do ! As for accuracy how about 10 shot 100 yd MOA consistantly . M4 sniper 22 1030 fps with a 29 gr .217 slug . Corbin has been making swaging available to the public for 50 years . One great American company WOW ! Viva Oregon and the Great Pacific Northwest
