I've used them in my .20 ga.Browning Cynergy & 'Bobwhite sxs and have had good luck with them & no recoil.They seem to work as well as my standard reload.I've reloaded the same 75 3 times so far with no problems.I keep 6/8 boxes in the gun room for the same reason you mentioned.I've used the .12 ga. # 8's in my Thomas Wild & 471 Silver hawk sxs's for skeet & some sporting clays with decent results.Have not reloaded any of the .12 ga. hulls yet.
