Hornady's factory load is a very good velocity-producing load if it registers at 2460fps.Did those guys use the best powder for that weight bullet or did they use what some say is the most popular powder? Everyone seems to think AA2200 is THE powder to use with every bullet. It works well with some but not so good with heavier bullets. I've run 115gr bullets to 2830fps out of a 16" barrel when the primer cratered enough for me to say it's max. I've pushed 130gr Sierras to 2530fps out of 16" barrels, 120s to over 2600 all with the same powder and it isn't AA2200, it's an old unpopular powder. Factory 110gr Hornady hits apx 2600 in the 16" 5R barrels. Do you want to compare handload to handload or factory to factory? Handload to handload in different barrels will get you a bunch of skewed data.
Hornady posted the info on their ammo, they aren't biased they posted the facts as they are.
I know this is about to turn into a party and I hate to miss the fun but I have work to do. I'll read the cliff notes later.
