Skip, I have shot the SKB 100 and 200's for over 30 years and have owned several.Regarding steel shot,I have two guns,model 100's, that were factory 2 3/4" 30" mod and full and chrome lined.Sending them to a smith with carbide reamers they are now 3" with one at cyl and mod and the other at mod. and mod.One for decoy work and the other for pass shooting ducks and geese.They have both digested several thousand steel loads of various sizes and show no major ill effects.the mod and mod barrels which have had a large number of BB and BBB through them may have an almost imperceptible bulge at the chokes.This is not measurable with my bore gauge and is barely visible as a reflection.I would say less than a thou.and certainly does not affect efficiency as the mod choke will kill cleanly with high velocity loads that are well centered, to 50 yds.The SKB guns are exceptional and have gone where my vintage guns fear to tread.
