Alliant Blue Dot is a handgun / shotgun powder designed for magnum loadings.
Bottom Line: 👎 I won’t buy again. But I need to find a substitute first, because I’ve come to like aspects of it.
- Cleans up very easily from powder measures.
- Decent amount of load data out there, claiming good performance at the high-end loadings
- Load data claiming very powerful loads in 45 ACP
- Good performance with heavy bullets in 45ACP
- Clean burning moderate to powerful 500 Linebaugh results.
- Meters poorly in Redding 3BR (but meters OK in automatic power dispenser).
- Reports of pressure spikes. Example. If I can’t trust it at the high-end, it’s not a useful “magnum” powder.
- Reports of higher pressure at lower temperature. Counter-intuitive, but I’ve read it from different sources.
- I have had poor consistency in 45 Colt.
Moderate flash. I’ve heard it’s supposed to have high flash, but in 45 Colt, or 357 Magnum flash is only moderate.
