In my experience, the 55 gr FMJ bullets are plinking bullets. Even the best of them seem only capable of 2 or 3 inch groups at 100 yards. I have had much better accuracy with hollow point or soft point bullets. The Hornady 55 gr SP in particular shoots very well compared to the Hornady 55 gr FMJ. The SP with Cannelure is comparably priced when purchased in bulk. I don't plan on wasting any more money (or primers or powder) on 55 gr FMJ bullets.
