Best Pistol Powder for 9mm Major?

Recommended Posts

Any good pistol powders but HS-6? Using for USPSA open division.

Winchester Auto Comp (WAC) is a favorite, along with HS6.

 

Those are the only two powders I've used for ten years.

 

Really there isn't any Best Powder - but many others are

also very good.

All your 9 major questions answered: 

There could be a number of reasons you make 175pf at 8.3gr while your friends use 8.9gr:

- different lot numbers (I've read about some hot lots of HS-6, maybe you have one)

- shorter OAL (it's not a big difference, but generally speaking the shorter you load, the higher the velocity)

- barrel wear (as barrels wear they tend to leak more gas around the bullet, producing less velocity)

- different brands of bullets (the friction characteristics vary from brand to brand, Montana Gold seem to be about the slowest)

- do their pistols have ports in their barrels or shorter barrels? (both tend to lower velocity)

I've used HS-6, VV-n350, and am currently using WAC. All good powders. HS-6 is the dirtyest of the three and VV-n350 the cleanest.

Does using a small pistol magnum or small rifle primer affect the burn cleanliness as opposed to a standard small pistol primer?

 

I use Hs6 in my 38sc and dont find it all that particularly dirty.  I do have 4# of 3n38 to try out after my Hs6 is gone.

I don't think it affects the cleanliness as much as providing "tougher" primer cups to resist the higher pressures of Major loads.
