[QUOTE="lancetkenyon, post: 1714638, member: 68875"] 5.56 Nato cases are usually thicker brass, meaning less case volume, but tougher and run at higher pressures than .223 Rem brass. Check your headstamp. You should be using the same headstamp brass anyway if you want the best accuracy. A load that is safe in .223 Rem might be over pressure in 5.56Nato brass. I use LC brass for my precision 69 SMK hand loads @ 3033fps. They have put a hurting on many a javalina and coyote, and a lot of jackrabbits too. 1/2MOA loads work well on steel out to 800-900 too. Even had friend's kids shoot mule deer doe with them with good results. For my varmint loads, I do run mixed headstamped brass with a moderate charge under a 50 VMAX @ 3300fps for coyotes/fox/bobcat/jacks. But those are usually 300 and in, so 1 MOA is plenty acceptable.
