I just loaded some .223 with H335. 21.6 grain using 55 gr Hornaday VMax bullets. The Hornaday book said I should be around 2900. I was consistantly at 2550ish.
16" barrel colt AR15. RCVS Chronograph at about 10' from the mussel.
Thoughts? Seems like I should have gotten a little more out of that charge.
