Confetti is not confined to old shells, either. Last year, at the Fall Southern S x S, I bought a flat of 16 ga. RST spreader loads to use in my very tightly choked Elsie. They worked well, and I qualified to shoot in the Challenge Event, but what a mess! Never saw so much paper in the air coming from a shotshell. Other shooters were noticing and laughing, too. Still got four boxes of 'em.
I shoot old roll crimped shells regularly in this gun at doves. They kill doves fine, but have a much higher incidence of bloopers than the pie crimped paper shells, as Mike noted. I get the distinct impression that pressures in some are extremely low.
