I thought only large rifle and pistol primer pockets had different depths and small primer pockets were the same. Is this not hwy you can use pistol primers in Hornet brass?
That is correct. Small rifle/pistol are the same size. Large rifle is taller than large pistol, but same diameter.
S&B primers are marked "SR", "SP" etc on the box. I use the SR and SP versions, have not tried the large versions. They are OK for blasting or target ammo, but I've had a couple fail to fire out of the last 1,000, so I wouldn't personally use them for defense or hunting.
