Burn rate can be deceptive.
Power Pistol appeared to be the perfect fit for me, like 4756, it's a notch slower than Unique on the chart, but when I tried it I didn't like it. Forget the tiny charges, the stuff really has a lot of muzzle blast and apparent recoil.
It behaves faster than Unique if you ask me.
Don't want to go to Blue Dot because of the rep of cold weather pressure spikes (here in MN I sometimes shoot below zero) and unpredictable behavior with 357 and 125 grain bullets.
So I'm back to Unique and HS-6.

C'mon IMR, lets have some data for 'Unequal' and 'Blue' in the 357.

I have high hopes for Blue to be my cold weather, magnum-lite powder.
