Best/Preferred Powder For 10mm

johnnyflake · Aug 16, 2016

I have just started to put together what I need to reload 10mm ammo, which is new to me vs what I have reloaded for many, many years, .45acp, .45 Colt, .454 Casull and .44 Mag & Spl.

What powder do you 10mm reloaders prefer, especially for full power loads? I am not asking for any receipies, just your preferred powder, for Mid-Range/Plinking Loads and Full Power Loads.

If anyone wants to mention their Pet Loads, it will be appreciated.

There is no "best" for any caliber. But some good powders IMHO are Power Pistol. HS 6. Longshot, CFE pistol, Unique or other brands along the same burn rates. Not to fast, not to slow

I happen to like Power Pistol for 10mm. (Be advised, it "barks" loudly.)

Power Pistol is my go to powder for 10mm. Meters great, economical, can run mild to wild.

I shoot 180s and 200s and have had good results with BE-86 for medium-power SD loads and Longshot and AA-9 across the board. LS and AA-9 are good for "real" 10mm loads.

Both BE-86 and AA-9 are flash suppressed.

I like Blue Dot. In my Delta, 10 grains with a 180 grain HAP yields 1,220 fps, and 9 grains with a 180 grain lead flat point yields 1,135. The R-P 180 FMJ runs 1,150 for reference.

The R-P 180s look (flash) and feel like a PP load. Commercial PP is known as BE-84. I should pull one apart and weigh the charge.

All good powders but unless you just want 40 vel, you need to feed the 10mm slower powders like AA#7, AA#9, Longshot, BlueDot, maybe BE86, but I haven't worked up 10mm loads with it yet. My fav for 200gr-220gr bullets is AA#9. Best accuracy with good vel & no smiley faced brass in my stock G20 bbl. I don't even bother with lighter bullets anymore. For me, the 10mm was designed for & runs best with 200gr @ 1200fps. Though I have wicked good 165gr RGS @ 1300fps load if I ever decided to carry the 10mm for SD.
Some love 800X but I just haven't gotten the accuracy out of it I desire. A#7 & 9 do far better. BlueDot can be very good as well, but the AA powders meter so much better.

But are then saying you get faster velocity from slower powders?? Can that be?Also how is that recoil

I load 12.6 gr of AA-9 under a 200 gr XTP for 1200fps out of my 5" Rock Island 1911.

Recoil is manageable; no worse than .40 out of a plastic gun. I can't complain about it. I'm also using a 26# spring to save the brass from getting chewed up.

VihtaVuori 3N38 ... darn sweet in 357 magnum as well!

RDub · Aug 16, 2016

The best powders for full power loads with 180 and 200gr;

800-X
Longshot
3N38
Blue Dot
AA #9

Power Pistol
AA #7

Power Pistol and AA#7 will get you about 90% of what the other powders can provide, but I've found them to be very accurate.

Which ever ones you can find you'll be happy with. Your gun will probably have preferences.

Never mind it was for Fred

I don't load 10mm, and my only experience is firing a friend's. However, were I to reload the 10mm, I'd consider AA5 and maybe AA7 first. Unique would also be a likely possibility.

BLUEDOT37 · Aug 17, 2016

Can't go wrong with Power Pistol or Longshot with 165gr. JHPs. They're also fine with 180gr., along with Bluedot. Surprisingly I got some very good accuracy with 13.0gr/2400 & 180gr Nosler JHP, in my 1076.

Lot's of very good information in this thread. I really appreciate all the input and opinions.

I'll be loading 180gn bullets and I am thinking of buying one pound each of #7 and 800X to try out and see what I come up with. from what I have read, I get the impression that #9 is better for heavier 200gn and up bullets.

Seems I have read this somewhere else.

For serious hunting loads I use Blue Dot and AA#9.

What a difference a forum makes. Here the most suggested powder is Power Pistol, elsewhere it was AA#7.

I'm in the AA#7 camp since my real favorite HS-7/W571 is no longer available.

You hit the nail on the head brother!

After much consideration, and I have changed my thinking several times now, but now I am locked in! I will be picking up one pound of each, Power Pistol and AA#7. That way I can test both powders and see what works best for us.

I truly appreciate all the input received on both forums.
