Hevi Metal pre-pandemic was about $1 per shell; now, not sure. True Hevi shot, which I had the good fortune of being gifted about 70 rounds 20 gauge 2 3/4” 6 shot about 20 years ago, is much more spendy…$3-4/shell? Anyway, I had a December pheasant hunt in 2001 where I knocked down 20 roosters with that aforementioned load, and retrieved 19 of them, mostly stone dead. Don’t recall the deal with the lost bird. 95% recovery on late dec roosters with a 20 gauge is pretty good, by my 28 years of experience of extensive pheasant hunting experience. Most lost birds are straight always, for me at least…tough to punch through the backbone…past 15-20 yards, IMO
