I would like to hear your favorite 10mm loads, including but not limited to details such as Bullet weight and type, power type and amount, fps, and purpose (hunting, plinking, etc).
The Viht 3N37 seems like a real charm, with low flash and clean burn. Have you seen a noticeable difference to other powders?
I can't find much for the SR4656. What draws you to this one?
That particular Viht powder gives excellent accuracy, and does not leave a lot of leftover residue like what some other powders do...
I load a lot of steel shot for waterfowl, and SR-4756 is a powder I always have on hand. I load this powder in both 10mm's when I'm shooting 200 gr. bullets on the heat of the Summer, and it has proven to be very accurate and reliable. Since it is a single base powder, it can be quite dirty burning in the cooler temperatures...
AA No. 7 is also an excellent powder for use in the 10mm. This powder and Viht 3N37 offer the best velocity out of my guns, and if I had to pick a single powder to use, I would have to flip a coin....
Where do you find Viht usually?
I have been blessed to find a few pounds of A#9, a pound of 800X, and a pound of CFE pistol powder.
I am in the OKC area and have the best luck at H&H.
180g LSWC / Win. Lg. Pistol primer/ Accurate Arms #9 with 12.2g @ 1100 fps .
My Colt Delta, S&W 610 revolver and Glock 29 all like the load. Shoots great.
