Yes, I am sure they are boxer primed:rolleyes: Now that I have outrun the smart asses around here.... I have just started reloading some .22 Savage "Hi-Power" brass from SB. It is actually 5.6X52R, the european designation for this cartridge. Anyway, repriming them with my LEE Auto Prime is a lot of exercise:mad: Any suggestions? I am using CCI Large Rifle primers. Might a different brand be easier to use? I was also wondering about trying large pistol primers. Your thoughts?
 
S&B 9mm is a ##### to deprime. I have gone so far as to give away that type of brass. Once the primer actually comes out (from way too much force) it's worse trying to get the new primer to seat. Pretty much any other brand is good to use. Winchester, CCI, Fed, etc.
 
Maybe it had a crimped in primer. hahaha one smart ass left.
Get a primer pocket uniformer and then you fix them all. These work pretty slick https://www.kmshooting.com/catalog/primer-pocket-correction-tools/large-rifle-primer-pocket-correction-tool.html
 
I find cci primers on the large side and S&B pockets on the small side. I use Winchester primers when I encounter tight pockets, and cci in looser ones.
A few firings and the pockets will loosen up...
 
CBSA shoots a lot at our range so I have a pretty unlimited supply of once fired 9mm brass and don't even bother picking up other 9mm brass like S&B so I can't speak to their SP primer pocket size. 45 brass is another story, however. Because S&B ammo seems a little cheaper than most other brands a lot of non-reloaders shoot it and I find quite a bit of it laying around. However, the LP primer pockets are definitely smaller than those in US company brass. I tried reaming them with my Lyman primer pocket reamer and also with my RCBS primer pocket swager but neither of them solved the problem. Then I discovered that a #4 drill bit with the point ground flat would enlarge the primer pocket perfectly to the dimension of Winchester, CCI, Remington, etc. It takes a few seconds of drilling per case (I clamp them in a bench vise before reaming) but I'm saving maybe 15-20 cents each and they are good for many, many reloads so it's worth my time to process them and I have only have to do it once.

I'm guessing you can successfully do the same thing with S&B LR primer pockets.
 
Any S & B pistol brass I have picked up, has been hard to re-prime. I suspect it is because the primer pockets are formed to metric units, rather than in fractions of an inch.... as with North American cartridges. Knowing the brand of factory primers used in S&B cartridges, would likely solve the issue, once and for all. I haven't measured any to verify.... but ,would not be surprised that that is why the primer pockets on S&B brass are generally tighter. Likely rifle brass, too.

I would imagine they use S&B primers...

any or most S&B brass i have come across (pistol or rifle) is harder to prime even when using S&B primers. ream the pocket or don't either option works.
