Tom Stevens
Winchester AutoComp

I've used this product before and have been pleased with its performance. It measures nicely thru my powder measure, burns clean and provides good accurancy in all my 9mm handguns. My next test will be in .38 Special loads. This is my first direct order from Hodgdon and I'm very pleased with their service.

Best powder for 9mm that I have found for my particular load.

Winchester AutoComp Powder

Honestly this powder is great for range loads IMO and also can be used in some bigger pistol loads. I mainly use it for 9mm and it works wonderfully. My only nit pick is I think it would be cool if you got a load data sheet with the order so then you have a physical sheet instead of going to the website to get it but like I said it’s just a nit pick. Overall amazing product itself

I use this powder for loading .45acp, Powder runs well in my loads. I load 6.1 gr for 200gr swc ammo and 6.5gr for 230 gr rn bullets, Have not tried it on defense rounds yet...That's next. So far real happy with it's performance.
