loaded up some 223 ammo and ran through a chronograph with surprising results.
Recipe: Lake city brass loaded with 26.2 grns of H335 with a 52grn HPBT sierra. Sierra book shows this round to be about 3200fps in there test gun. I was able to get about 3560fps with great groups and no over pressure signs. This seems way hot to me, recheck charge weight and is correct.
Not real sure what to think, seems way to hot for 223. I suspected chronograph but check it against another load and was within 100Fps of what sierra stated. Does seating depth affect velocity ?
Should I be concerned with the velocity of this load ?
Thanks in advance.
