I have an 870 with a Bansner sleeved barrel have used Fed. 4's for shells. Thinking about changing shells because the Fed,'s have issues ejecting. Anybody have any ideas on shells? Twelve ga. 3'' 24" bbl. have always used 2oz. 4's with good results.I think the sleeve mikes at .645.
I have a 3" 1100 Bansner sleeved and it shoots Remington 4X6's very well.
I originally shot No.# 4 Federal's until I stumbled on to the 4x6.
