hit some of the powder companies online manuals, they are starting to show coated bullet Data...
FYI, I have a very low opinion of Universal when trying to get close to max charges it gets real spikey and you start getting big swings in velocity,,, which to me says too much pressure.
So far I am loving the new BE86 for coated bullets in 45 ,and 357,, a bit faster than Power Pistol without the booming muzzle flash, a bit slower than Unique.
