Re: reloading for an ar 15 223
there are a couple of things that I do different when reloading for an AR-15, first is that I run more neck tension than for a bolt action but I dont crimp (or use cannalured bullets).
On a bolt action I never full length size my cases unless they need it, on an AR15 they need to be full length sized every time. set-up your FL dies so that you are setting back the shoulder about .001" this will also slightly size the body and web area.(AR's require a slightly looser chamber-cartridge fit to ensure reliable operation).
as for powders it depends on bullet weight, what bullets are you planning on using?
It takes 43 muscle's to frown and 17 to smile, but only 3 for proper trigger pull.
