AR Comp for 223 bolt gun

[rebs]

Are you guys using a magnum primer with AR Comp powder 77 and 80 grain bullets in a 223 bolt gun ?

With my limited amount of testing, I have only used Fed 205M primers so far.

I'm going to test all of the cci primers but in the reviews I have seen the standard 400 worked the best. I have them all so why not.
