Yes ,won't hurt barrels

Dave, you can load my load as a 2 3/4". Simply use the same wad in a taller model. Won't be a dimes worth of difference. In my opinion and experience you could also use the same wad and stack a cork wad on top, simply filler for the crimp. They weigh nothing and should make very little if any difference in pressure. This is a mild load anyway
I grew up as a lead 6's guy for ducks but went to 5's in bismuth. It's good but actually is slightly less dense. The load above has been very good for me.
