CCI # 41 primers

Harder cups? Thicker cups? Both??
If so, might that also mean slightly larger diameter?

The folks at CCI will tell you that they are the same as 450's. That's all I know about them.

From another forum:

"Small Rifle Magnum

CCI 450 - same thicker .025" cup as the BR4 and #41.
CCI #41 - commercial version of the fully-qualified DOD primer for use in U.S. military ammo. With this primer there is more 'distance' between the tip of the anvil and the bottom of the cup than with other CCI SR primers. .025" thick cup. Same primer mix as CCI 450.
Remington 7 ½ BR - A match or "bench rest" primer. Hornady, Handloads.com, and Chuck Hawks classify this primer as a Magnum, differing from other sources that classify it as a Standard. .025" cup thickness.
Wolf/Tula Small Rifle Magnum SRM - hard, less sensitive brass cup intended for AR15/military rifle and high pressure rounds - #KVВ-5,56M.
Wolf/Tula Small Rifle 223 SR223 - #KVB-223M "This is the newest primer available in the Wolf line. It is ever so slightly hotter than the small rifle magnum primer and it comes with a brass colored thick cup. This primer can be used in place of the SRM primer or used when a different powder is used that is hard to ignite."

Thank you, jepp2. I have some of both of those Wolf primers. Might be just what i need.

I don't have specs, but I do have personal experience. I have a 6 Beggs in a sleeved 722 action. The bolt has been bushed by Gre-tan. While experimenting with some very hot loads using LT 30 & LT 32 I stretched my primer pockets quite a bit. I also found that the load that produced the best accuracy would blank CCI BR-4's, which I've used in all my bench rifles for several years. I had some 41's and decided to try them. I have used nothing else since. The 41's coupled with a stiff load of LT 32 produces excellent accuracy and do not blank. The primer pockets, although loose, haven't gotten any worse. It's a good combination for me.

Rick, thanks for sharing your experience w/ the 41's. I did buy some for experimentation, so looking forward to how they work for me.
I also have some moderately expanded pockets, which led me to this inquiry.
Thanks,

Thanks for the info guys! Been using CCI 450 with good results. Might be worth trying the 41's or the Wolf when it comes time.
