First post, first question

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!
