Redding 2-die Set

I currently reload .223Rem on a Rockchucker for my heavy-barreled varmint rifle using a Redding, Neck Sizing, Series A, two-die set (82111).  As I've got an RL550B on order as well as an AR-15 kit (12 weeks and counting), I'm trying to figure out whether I can use my Redding dies to reload for the AR-15 on the 550B.

I have about 750 rounds of Georgia Arms 223/5.56 reloads that I plan to run through the AR-15.  I'll use that fire-formed LC brass to reload for the AR-15.  I'm planning to keep the bolt-gun and black rifle brass separate.

Dillon sells Redding, two-die rifle sets; but, I don't see any discussion as to whether they can, or should be, used in the 550B press.  For my bolt gun, I don't need or use a crimp.  The bullets I plan to use don't have a cannelure.  My Redding dies do not provide a taper crimp; however, I plan to use Win748 powder which should result in a compressed load, mitigating the possibility of set-back.

This if my first foray into progressive reloading.  I'd appreciate any recommendations as to whether I can use my current dies and, if so, any special considerations in setting up the new press to accommodate them.

Thanks for your help.

 

The Redding dies will work on your 550B. I would probably buy a set of Dillon .223's, as the bullet seating depth will be different most likely than the bolt gun and if were me, I'd full length resize the casings or else make sure I used a case gauge that Dillon sells to check the headspace on each round. All it takes is one round out of dimensions to cause a slam fire in your AR.

I am not a fan either with compressed loads in any gun. There are hundreds of different powder combos for the .223 and your AR.

 

gobblr addict: Thanks for the reply. I did some on-line reading after I posted my note. Everyone recommends full length sizing for semi-auto. I've ordered a Dillon die set as well as a case gauge. So, I'll be using a taper crimp and confirming proper sizing.

I've always tried to find powders that fill up the case completely. From what I've read, a full case leads to improved accuracy. Many powders designed for specific calibers do just that.

Thanks again for you feedback!
