CCI41 primers Alternative???

The CCI #41 milspec primer is ballistically equivalent to the CCI 450 standard small rifle magnum primer, without the 'sensitivity protection' that is found in their milspec CCI #34 and CCI #41 primers.
For slam fire purposes, the milspec primers are called for, but for bolt guns, you can go with their CCI 250/CCI 450 primers, which are their magnum primers.

I load tested CCI BR and CCI#41 primers, AR-15 everything the exact same but the primers obviously. Both Chrono'd at 2740, no changes whatsoever. Definitely don't buy Fiocchi though, pierced primer city. CCI BR will work fine.
The main difference between CCI #34 and CCI #41 primers and standard primers is the height of the anvil is shorter requiring more force to set off the primer. For the AR15 rifle any primer with a cup thickness of .025 will work fine, with thinner cups the risk of slam fires increases. The greatest risk of slam fire is if a single round is loaded WITHOUT the magazine in place and the bolt is allowed to slam shut. With the magazine in place bolt velocity is reduced as it feeds from the magazine slowing the speed of the bolt and it free floating firing pin.
Now some food for thought............
Remington ran the Lake City Army Ammunition Plant from 1941 to 2002 and used its 7 1/2 primers in 5.56 ammunition. Remington didn't use CCI primers at Lake City and Winchester who ran the plant after 2002 didn't use CCI primers. And the Sierra manual for .223/5.56 service rifle AR15 loads uses Remington 7 1/2 primers.
Now look at the flash photos of the primer tests at the link below and see which primer looks like a mini flame thrower.

Think about it, Remington ran Lake City Army Ammunition plant and had to use recycled Winchester ball powders and they used Remington primers in this military ammunition.
It's likely a personal preference,but I would have worried little about the recycled Win. powder. I still shoot some WW2 surplus powder with fair success. The Remmy primers,don't have much experience with them. Your link certainly showed them in a good light though.
I have to repost this info as I was looking for info on Wolf primers.
