Power Pistol in .357 Magnum Loads

[GunAdmirer]

Anyone have any experience with Power Pistol in .357 Magnum loads? I really like Power Pistol in 9mm and have a lot of it on hand.

I wonder how well it works in larger capacity cases like the .38/.357?

Consistent velocities? Accurate? Clean?

I just ran a test batch of 6.0-7.0 PP under a 158 gr. Hardcast TCFP.

I haven't chrono'ed them, but 6.4gr. "feels" right for a moderate load. Pressure is not really any different than 6.5gr of Unique - which is well within pressure limits. My estimate is around 1200fps based on Unique load data.

I will say this: PP has a very nice magnum-esque boom and flash! I like it!

supposedly PP burns hotter than Unique and therefore tends to cause more leading. In my first test i only put 50 rounds downrange - leading with Hardcast bullets was non-existant.
