Don't ever, I mean ever use them in a 12ga with rifled barrel.

I mean ever. I tested out 20 today and it started off mediocre at best with 3" groups at 50 yards, By the time I finished shooting all 20, I was up to 7" groups or more.

Got home and worked for 2.5 hours getting out the leading. Still haven't get it all out. Big slivers of it coming out. Never seen leading this bad.

If these are Foster style slugs your going to have a fair amount of lead build up. I've shot Foster slugs in a rifled barrel but sabots are the best.
