Preferred Primers For 223?

[Dusty44]

Which SRP do you use for your 223/5.56?

Some threads in other forums have discussed a preference for CCI 41 primers.  WSR and CCI 450 have been mentioned.

Some reloaders like magnum primers for the heavier cup metal and there has been mention of slam fire with some specific individual's rifles and some primers.

What is your preference and your experience with the primers you have used?

I use the Wolf and Tula 223 primers.

I use the remingtons. They fit primer pockets that have been crimped before easier.

I've always used Winchester Standard Rifle Primers.
