Just reloaded a box of (unfired) Winchester SuperX 12 GA for target blasting. Got to wondering if the problem with sticking on extraction isn't so much the shell base, it's pretty short, but rather the hull itself. These are dead smooth on the outside as opposed to other hulls that have fine ribs. Seems like the ribbed shells would have less actual surface in contact with the chamber, and maybe easier on the extraction. 'Course it could be the base as many feel, or the particular plastic composition of the hull as opposed to other brands.
Chime on in.......
