Thanks to people that dont police their brass, and a police dept with 7 full auto M16A1's given to them by Homeland Security for $45 per rifle, I now have two big 5 gal buckets of nice clean 223 brass. I dont have a mouse gun at the moment, but I am thinking about reloading this brass just to have handy. I want to reload it for the later made rifles with the current barrel twists. I was thinking in the 60 grain range with either H335 or BL-C(2) powder. I am leaning towards the BL-C(2) because I use this in .308 and I could buy it by the 8 lb jug. For current AR-15 barrel twist rates, would H335 or BL-C(2) be the better choice?
