loading some 9mm using Hornandy 124g xtp for a bullet, Unique for powder. Loading at 5.5 grains. New bullet for me and was wondering if anyone else has loaded this round and with what weight of powder ?

You're definitely in hot territory.

I load that one at 5.0 grains Unique, WCC 02 brass, Winchester sp primer and 1.060" overall. I've found it to be a good duplicate of Hornady's standard pressure round. Chronograph shows 1,123 fps from my 4" barrel / Smith 910.

All else being the same, if I move it up to 5.3 grains, it's going 1,200 fps, which I consider +P territory. Never had pressure signs, but be aware it's above posted data.

Both are very accurate. You're likely going to catch a little bit of a break loading them as long as you do, but FYI Hornady shows max as 5.0 grains. Be careful. Unique is generally forgiving, but the lack of volume in a 9mm case isn't.

The old manuals show 6.0. Stephan A. Camp used 6.0. I tried 6.0 with a 125 Zero JHP and it shot great out of my G17 and LC9.

Thanks for the reply. I only loaded 10 rds at that load for testing purposes. what I went off of was the 2011 Alliant Powder reloaders guide. Granted it isn't using the Hornandy 124 xtp its using the 124 speer GDHP. In the book it says OAL 1.120" max charge of 5.8 unique with a velocity of 1180. Im new to the reloading and welcome helpful info.

Just a suggestion, but you don't really need to hotrod your pistol. I get 1050 fps with 4.0 Red Dot and a cast or plated 124 grain bullet. Buy two boxes of SD ammo, shoot one to see how it shoots, put the other one aside for social work. Then shoot the bejesus out of that handload.

Hornady's 8th edition for 9MM 124gr. XTP's at an overall length of 1.060" lists 5.0 grains of Unique as maximum and 1100 fps. They used Hornady cases and Win SP primers in their test. I'd stop at 5.2 maximum with the 124 XTP's. They seem to create a little more pressure than does the Speer Gold Dot 124 HP's. I load the Speer Gold Dot 124 HP's at 5.4 grains in my G19's and get approx. 1135-1140 fps but the oal for the Gold Dots is 1.125". Don't think you'd get into trouble at 5.5 but it is getting into +P territory.

Yeah, light loads shoot the same as hotter ones, or better. They are easier on the gun, and the huge margin for error with the reduced pressure is a big plus. 3.5 Bullseye works great with a 125 cast bullet. So does 4.5 Unique.

Thanks for the info. Actually I don't want to hot rod my pistol. I want to shoot smaller loads. Unfortunatly most of the info I can find is conflicting and like I said I'm new to the whole process. I'm ingorant to how low of load that can be put into such rounds. All info I can find gives maxium. And like the info I find as on here is conflicting. I loaded another 10 rounds at 5.0 and stopped at that just for the fact I wasn't sure where to go with this. I do appreciate all the input that each of you have offered.

That is a top end load but terrificly accurate in several of my 9mm. It's pushing 1200fps mark in a G17.
