I am going to be buying an AR type rifle in the very near future and was wondering, because I have never had a need to know til now, does anyone here load the 5.56x45 NATO rd for thier AR/M4 and is there 5.56 NATO dies made by anyone or is it standard practice to use 223. Remington dies? I have looked and have found none anywhere. Is it possible to reem out a .223 die to the 5.56 dimentions? I'm sure it is but I would like to know what anyone else has done and the results of thier work if I can find any. Thank you all in advance. 44
