Hi guys... I'm fairly new to reloading, 45 ACP so far without issue, and today I reloaded my first 9 MM. Here's what I loaded: 115 Grain Hornady JHP XTP 5.9 Grains of Unique Winchester WSP Primer 1.075 C.O.L Here's my issue... I have both a Sierra reloading book and a Hornady book. The Sierra book shows a range for Unique powder from 4.9 to 6.6 Grains for a 115 Grain JHP, with a 1.050 C.O.L. The Hornady book doesn't show any data for Unique with this bullet, but it shows the C.O.L at 1.075. When I charged the case with 5.9 Grains, it almost filled up the case (I weighed it at least a dozen times to make sure I wasn't reading it wrong). I tapped the case a little to settle the powder, but I believe it still got compressed when I seated the bullet. I chose to seat the bullet to 1.075 C.O.L as per the Hornady book. My main question - does anyone feel this may not be a safe load? Second - is it even possible to put 6.6 Grains of Unique in a 9 MM Luger case? (no, I'm not going to try it... I'm just curious) Third - If this load is ok, when should I get concerned with a compressed load? I know there are more than a few other powders out there I could use instead of Unique, but for now I'd like to stick with Unique. Any thoughts or advice would be greatly appreciated. Rich.
