Just finished loading 100 rounds of .223 on my Hornady LnL press. Using the Hornady 55 grain FMJBT that I got free for buying the press with Alliant's new AR-Comp powder for AR rifles. This is my second batch using this powder. The groups I got with the first batch were impressive...all within the size of a Quarter @ 100 yards.
