10mm Favorite powders ?

[old pipefitter]

New to Handloading the 10mm. What are some of your favorite powders for bullets in the 180 and up range. I have some of the usual suspects. AA9, Power Pistol, AA5, HS-6, Unique. TIA

BE86, nice and snappy

 

[Charlie Foxtrott]

Power pistol

Or longshot.

I mostly use Blue Dot and Long Shotshot, usually 180gr bullets. I've read that Blue Dot can be temperature sensitive, but I've never had an issue; good results with both powders.

BE86, nice and snappy

and flash-suppresed, fwiw.

I'm with dmar…blue dot and longshot are my two favorites.

I don't load the 10mm but my shooting buddy does. He used nothing but HS-7 (W571) in the 10mm until not was no longer available. Since then he has went to several powders, some already mentioned. He now uses AA#7 and likes it a lot, not as much as HS-7 but fairly close.

Have had great success with Accurate No 9 and No 7 with 180's and up. For less than max speed True Blue works quite well. If I had to pick one for all full power ammo, I like No 9 a lot but it does take more of it than some powders. But it does bring the speed and accuracy.

AA9 and 800X

Under 180 gr Accurate #7, over 180 gr #9.

 

[10mm Shooter]

I shoot a ton of 10MM and Blue Dot is my go to powder for 180gr projectiles...

 

[Goblin]

I only use 180s and Blue Dot since I'm happy with the results. Both lead and jacketed bullets.

Blue Dot works for me.

Longshot just LOVES the 40 caliber and it's is currently available. Take note a lot of the powders mentioned are currently Unobtanium.

As for examples, from the Hodgdon Reloading center you can have a 180 grain bullet hitting 1245 fps. That will get some attention. It will also have some neighboring shooters asking if that big old stainless 610 is a 44 Magnum.

Then there is my personal favorite, a 40 caliber "Short & Weak" pushing a 165 grain Speer Gold Dot to a chronograph verified 1165 fps, a load that is definitely NOT weak.

Powder coated 180gr lead pushed to 1225fps by HP38 and no leading!

Another vote for Blue Dot. 800x is great if you can find some. It's been discontinued.

In the past I've used Blue Dot and HS6 for full-charge loads with jacketed bullets. In target loads with lead bullets, always 231/HP38. Have not gotten around to trying Longshot yet, but will. Best accuracy has been with Blue Dot and Hornady 200 grain bullets.

AA#9 for 165 gr Berrys or Xtreme plated.

 

[mtgianni]

AA9 or Power Pistol.

Longshot is my go to for the 10 mm. It has seemed to give the best results for me in my pistols. I worked up some loads and was able to do better then published results in current manuals. Three different pistols, and the only one that exhibited signs of excess pressure was a long slide G40. Both the compact G29, and full size G-20 showed zero signs of an over pressure loading.

Just to keep things simple I lowered charge weights so that all are the same. But still over what hogdon said was a max load! Plinking loads, not so hot, full bore loads are hot to trot.
