I'm planning on buiding a 20 wildcat and can't make up my mind on which one. Any and all input would be appreciated. I've narrowed it down to these= vartarg, practical, tactical. What problem's or con's has anyone had with these. Please keep reply's to these three. I understand the draw-back to 221FB brass. Mostly just hunting those paper bug hole's. Thank's Dale, aka 'possum'
