I recently picked up a Glock 20SF and would like to start handloading for it considering the cost and availability of 10mm ammo these days. I do load for 9mm and 45acp, just wondering if this would be an acceptable powder for 10mm. Widener's CPP
I have had good results using it in my 45 and 9, just don't know if it would be fast enough for a 10.

Man you gotta have a death wish to use a ball powder in a situation like that.

4.5-5 grains of WW231 works with the 180 grain family of lead bullets. Nice mild load that runs about 800fps from my SW1076
10 grains of AA#7 or 11.0 grains of Blue dot works for the jacketed 180s. Full power load–––– 1200 or so fps.
9.5 grains of AA#7 or 10.5 grains of Blue dot works for the jacketed 200s Another full power load. 1100-1150 fps.

I see little reason to shoot a light bullet in 10mm

Powder is the cheapest component per load, so I don't think there is much reason for you to make what you have work if it's not the best choice.

I have used Blue Dot and Power Pistol with 10mm... I'm really not sure which I like better or worse, but both shouldn't be much over $20 for a pound.

Glocktalk and AR15armory both have dedicated 10mm reloading sections as well, and both are worth checking out. They might be a little slow but there is a ton of data.

I would have jumped on that deal years ago. Anytime I saw a new surplus, data powder or new manufacturer I could not resist trying it. Now days I stick strictly to what I have found works best in pistols. For 10mm on a 1911 frame I have settled on a 150 grain Nosler with 8.2 grains of Unique. A pound will load over 800 rounds and the load is sweet to shoot. All that said I do wish I had bought more DP73 when it was around. The powder Stan Widener has listed there looks too fast for my taste based upon the load data he shows. Oh Yeah, It shows Out Of Stock now LOL.

I just worked up some loads for 180 gr jacketed using AA#9 . Test loads were per Accurate Arms' load data ranging from 12.1 to 13.4 gr, all worked great, I settled 13.1 grains of AA#9

I was testing some 170gr SCWHC with 8.5-9 gr Of Bluedot very nice 25yd load !

Unless you're planning on loading your 10mm to 40s&w like velocities, you need a slower burning powder. As had been said, the powder is about as cheap as the primer in terms of cost per round. The bullet dwarfs the costs of the other components combined.

Say you spend $20 per lb for an 8lb keg of Power Pistol powder (great choice for a 10mm) and then assembled your Starline cases ($136/1000) with CCI LPM primers $32/1000), 10grns of powder (over a full charge), and 180grn Hornady bulk bullets ($312/2000). What would the cost per round be?

The order of component cost, high to low would be as follows:

1st - Bulk Hornady bullets would cost you about 15.6¢ each ($312 / 2,000 bullets)
2nd - CCI LPM primers 3.2¢ ($32 / 1,000 primers)
3rd - Power Pistol powder 2.9¢ per round ($160 / 56,000grns *10 grns per round)
4th - Starline cases 2.7¢ per round (assuming 5 cycles - $136 / 1,000 cases /5 reloads)

Your total cost for this hypothetical round would be or 24.4¢ per round ($12.20/box of 50) and only 2.9¢ (11.9%) of it would be powder.
