Whats better, 9mm or .45. There is no "better" powder.Granted pickins are slim..what's your favorite powder for 9mm?
This seems to be the last thing I need to get some ammo cans full. I'm not looking to try to be a sniper with my Sig...but would like "quality factory load" type if not a bit better.
To be honest you can load 9mm with any powder on the market right now if you observe pressures within the limit of the firearm.
Some slow burning powders might get the bullet stuck in the barrel, but I'm just painting a broad brush for example.
Personally here is the way I selected powders and its by pressure vs velocity. Pistol at close competition or combat ranges do not require precision loading. You can be kinda sloppy and not have any issues with accuracy staying within the manufactures recommendation. If one wants to go wildcat the liability is on you.
If one can get a lower pressure with the same velocity with a lower powder charge, it stands to reason you can load more rounds with a pound of powder although its a minimal thing.
It really comes into play when reloading for centerfire rifle. Pressures/powders/bullets/weights/brass, etc all become a factor at long range.
So, with the OP's request, I hope there has been some added data to get some of these folks that are on the borderline of reloading to get involved.
