Hello. I don't have the Hornady manual and just came by 500 rounds of Hornady 180g 40047-X rounds cheap. They are FMJFP and measure .606 long by my calipers. Does anyone know the charge for Unique and COAL I should be using for my Glock 22 (40 Cal)? I used 6 grains and a COAL of 1.125" for 155 grain Hornady XTP's and had real good luck.

I'm leaning toward 5.1 grains of Unique with this load because the Lyman Manual (the closest I have on hand) lists starting grains of 4.9 and max charge of 5.6 for Unique but this is for a Sierra JGP #8460 180 grain (they recommend COAL of 1.115" for that and it's a very similar looking bullet). Still, without having any more 155 XTP's to compare total bullet length and ogives on, I'm kind of at a guessing point for COAL on these 40047-X's. Any advice you could render on either subject but especially COAL would be greatly appreciated. Thanks.

Well, I can not be of much help. The latest Hornady manual shows the 40047 FMJ-FP as discontinued.

In the loading data for the 40 S%W they do not show any Unique loads at all that I can find.

The recommended COL shown is 1.125 inches.

Alliant data shows 6.7gr max of Unique with a 180gr Speer. Another source I looked at listed 6.4gr with generic 180gr JHP. The data for 180gr Sierra listed the 4.9min and 5.6gr max again with Unique. I'm loading 6.7gr of HS6 with 180gr Berry bullets and some bulk remington bullets I found. This was the most accurate in my Glock.

Thanks, guys.
