Terminal performance of accutips questionable? My sister used them exclusively for several years in her 870 20 gauge. I don't know if you realize it but Illinois produces some of the largest bodied whitetail in the lower 48 and she has taken some seriously big bodied animals over the years here. Never had a problem with terminal performance from the accutips. She has since switched to muzzleloader and her little 870 slug barrel is pretty much collecting dust.
