Unique is a great powder and I use a lot of it however one of it's known issues is at about 5 grains or less it becomes inconsistent and does not often burn completely and leaves unburned flakes. Also in lower charges it does not seem to expand cases upon firing and results in dirty blow by and blackened casesUnique is a very old, very time tested, very relaible powder, with the flexibility to use in many pistol and revolver cartridges.
Accurate 5Are there any preferred powders? If the primers are small vs large for 45, does this effect the preferred powder?
I never loaded as few as 5 grains. I have heard of many 8.0-8.5 loads. Amazing that Unique debuted in 1912. Back in the 70s, I fired Detonics prototype #4 with 230 hardball over 9.0 Unique. But, the gun was being shot by Sid Woodcock, Detonics president, who was testing a front sight attachment method for durability. He very kindly offered me a few rounds through it and I readily agreed. Very snappy, but not uncontrollable. And the front sight, mounted with a single 4-40 socket head screw, stayed put.Unique is a great powder and I use a lot of it however one of it's known issues is at about 5 grains or less it becomes inconsistent and does not often burn completely and leaves unburned flakes.

There is data for loading it up to 8 grains for some .45 loads but I have found 7 grains to be pretty hot and real snappy. Not dangerous by any means but just getting 'up there'
I have found it to be more practical in longer, straight walled cases like .357 & larger.
I thought I once read it was 1899 but I could have been mistaken.Amazing that Unique debuted in 1912.
I thought it was 1903, or even the late 1800s, but there were changes of ownership and the rights to develop and market the powder. 1912 is the latest date I have heard. Still, very appropriate for use in a 1911 pistol.I thought I once read it was 1899 but I could have been mistaken.
Man, 9 grains would be pretty snappy in a .45 no doubt. Heck I am loading .30-30 with 9 grains and 135 grain lead bullets.
From .25ACP all the way up to .45ACP, it has you covered. There are few which are just classic powders, and Bullseye is def one of them.Bullseye has forever been my go to.
Yep - definitely a 'cornerstone' in the world of pistol cartridge reloading!There are few which are just classic powders, and Bullseye is def one of them.
