This is the handload I use the most. I put a very light taper crimp on all handloaded 9mm ammo. It's just enough to remove all of the flare from expanding the case mouth for bullet seating with maybe a very, very slight inward curve. This is an extremely accurate load out of every Hi Power I've tried it in, including the FN Competition Model. It groups very well from the CZ-75 and SIG-P210 as well. If I could only have one handload in 9mm, it would be this one. Despite its not being so aggressive an expander as the Sierra and some other brands of JHP bullets, do not under estimate what this bullet can do. It has proven very effective on small to medium animals including Texas deer… assuming proper placement.
Hornady 124-grain XTP
6.0 grains Unique
Winchester or Federal Small Pistol Primer
Federal, Winchester, Starline, or IMI Cases
LOA: 1.11"
Average Velocity: 1243 ft/sec
Notice that with 0.2 grain less powder than the Unique powder charge for Sierra's 115-grain PJHP, we get the same velocity. I can only assume that the slightly-heavier XTP allows for more efficient or complete burning than the Sierra does, at least with Unique in that charge range. Though I've not done it yet, I suspect that Sierra's 125-grain 9mm PJHP might make a very nice bullet for folks liking the "turn-inside-out" expansion thing. Corbon's 125-grain +P JHP uses this bullet and it has proven a bullet capable of very fine accuracy.
