I am going to get into trap and skeet shooting. I would like to try clays also. My range has recently gone to steel shot only. What choke(s) should I use to ensure that I will not damage my barrel? What size shot should I use, # 8 ? I use a Remington Special Field, 20ga., English stock, with a 22 in. bbl(I think). I have used it for birds with full or Mod...close covers I/C.(Rem Chokes) Lead shot. I have a skeet choke, never used, should I use that? Thanks ahead of time.
