I must be doing something different. I get 10-15 loadings from Hornet brass.
I get slightly better accuracy from the W-W, but slightly longer life from the RP.
Heck, I've got some .22Hornet brass that I aquired in the late '70's. Mixed RP and Win.
However, the best Hornet brass I've used is the Sellier&Bellot. It is much more uniform that either the U.S. brands, and has a much smaller flash-hole- requiring a smaller decapping pin as with the .22 and 6mmPPC rounds. I routinely get under 1moa with my Ruger M77/22KBZ with Sierra 40gr HP's over either Hod LilGun or H110. Only match prepped Win will do that. (Neck turned for uniformity, reaming flash-holes and primer pockets, weight sorting (more important with the Hornet than any other cartridge......) ect.
Normally I don't do all the above any more, except with the Hornet. I've got 100 new Winny's that I haven't started on. Maybe some rainy day........
