    have a quick questions about some primers. im reloading for a 223, and i bought remington 7 1/2 rifle primers. everything that ive seen has said that they are for magnum rounds like your 222 mag and such, and that they could cause to much pressure for a 223. havn't looked to much into it. just was wondering if i can use them or not. thanks.

    Sorry, but you guys have been given some bad information.

    First, the 223/5.56 is a high pressure round and the Rem 7 1/2 primer is the correct Remington primer for high pressure rounds. The Rem 6 1/2 primer has a very thin cup and is designed for low pressure rounds like the 22 hornet.

    From Remington's web site.
    In rifle cartridges, the 6-1/2 small rifle primer should not be used in the 17 Remington, 222 Remington, 204 Ruger or the 223 Remington. The 7-1/2 BR is the proper small rifle primer for these rounds.

    Link.

    BTW Rem 7 1/2 primer are all I use in 223/5.56, 6.5 Grendel and 221 Fireball luv em great primer.
