Accurate No 2 (Improved) is a modern fast-burning pistol powder that is optimized for light loads, although the manufacturer also advertises it for full-power defensive loads in short-barreled firearms.
The powder is sometimes called “Accurate #2 improved“, because at some point it was made more bulky to give better case-fill. Volumetric data changed, but formulas by weight are still valid. Since the powder became more bulky, old data would fail by sticking bullets in the barrel, instead of exploding the firearm. But beware of compressed loads, unless they are noted as such.
Bottom line: 👍 Still evaluating. I haven’t chronographed any loads yet, but so far this has been an excellent powder to work with.
- Very fine granules meter well. Most consistently metering powder out of my Redding 3BR so far. Also, no “hangup” feel as with True Blue.
- (Claimed) Low Flash.
- (Claimed) Position insensitive.
- Can be a bit messy, because the fine grains get everywhere.
- Volumetric data may be obsolete.
Density (per manufacturer) 9.800 grains/cc ±5.5%
