Re: small base .223 dies for my AR 15?
Nope, I'll wager standard dies will work just fine. I reload tons for several 223 rifles and use standard dies. Never had any problems whatever. However, as stated, your milage may vary.
I would load about 20 rounds and try 'em out and see, but I bet they will feed just fine. If they do, load a couple hundred and have a fun day at the range.
