    Basically i have a butt load of 10mm brass, and a butt load of 150gr nosler sporting bullets, and a butt load of unique powder and cant find jack S**t for a load suggestion. any of you 10 mm guru's have a pet load for a glock 20 that would be both fun and stout for sporting purposes?

    The closest thing I could find was 7.4-7.7 grains for a 155 grain bullet.

    Lyman 47th shows data for a Sierra 150 JHP. 6.5 @ 994 (21.8K CUP) to 8.1 @ 1265 (29.5K CUP) Should get you close if you start low and work up.

    If you ever run into this again, you are safe using similar bullet specs above your current pill's weight by say 5 or 10 grains. If you look at any loadbooks at all, you'll see there is a consistent trend in the lighter pills having more powder under them. Sorry if I'm playing Capt. Obvious here. Therefore, by picking a spec on a 155 grainer, even at it's max, you would not exceed it for your lighter 150 grain projectile.

    That said, I know how you feel, not having published data does make one's decisions more tenuous considering we're talking guns here.

    If you have future issues, be quick to contact the powder or bullet manufacturer. I had the same issue with a 165 sierra JHP for my 10mm and a Sierra rep got back to me in less than one business day with the information I needed to proceed.
