So I'm finally getting into 10mm. I have a lot of accurate 7 and according to the Hornady number 10 book it loads 10mm. Anybody have opinions on this? I looked and saw there are some high key recommended powders but like I said, I have a lot. Any experienced opinions would be awesome! Oh and if t matters I'm probably getting a Kimber Camp Guard.
Experience reloading 10mm? Lots!
No #7 though.
It is, IMHO, a fine powder for 10mm. It will provide very respectable performance and meter well. #7 is a top performer in 10mm for bullets up to about 165 grain. Heavier bullets will see slightly better performance with a powder that is just a touch slower. It still is very respectable, but #9, BLue Dot and Longshot will give a few more feet per second before hitting pressure max with the heavier bullets.
Alliant powders are cheaper around my neck of the woods, and so I tend to favor them. If #7 were cost comparable locally to what I paid for unique when I started out, and what I pay today for BE-86, I would be saying I burn a lot of #7. But economics and my preference for 180-200 grain bullets, which are purely regional and personal preference, have limited my exposure.
Welcome aboard.
Thank you! #7 is cheaper and easier to find for me right now. The Alligant powders are more scarce for some reason. Plus I use #7 for 9mm suppresed so I have a lot. Not oppose to a few pounds of others though.
#7 works fine.
Considering that #7 is almost the same as Blue Dot, just a hair slower, depending on the chart you are looking at, I'd call it acceptable powder for the 10mm. I tend to gravitate to the slower powders though and have found that 2400 has a sweet spot for the 10mm and 180 gr bullets. I probably have most any of the powders but Blue Dot and 2400 seems to be more accurate from my particular 10mm. Since you have a bunch of it, that would be where I would start. You don't always have to shoot full house loads anyway or heavy weight bullets. I'm still looking for a good accurate load with 135gr Rainiers HPs. I have one for the 115gr Lehigh Defense at 1500'ps using CFE Pistol. Now that's one solid copper bullet that gets there with authority.
I had no idea Lehigh made .40/10mm!!! I use the hell out of them on .300blk. They make a fantastic pig killing round! Good to know!
