Alliant 300MP

[N310toN170]

I looked into Alliants new powders and picked up a pound of their new 300MP as it seemed to fit the profile that would make it a good 300WTF powder.

Anyone have any starting recipes they'd be willing to share (sub and/or super) or do I start with the low end of a .357 mag and work up/down?

I can tell you that you CAN fit 22 grains under a 110 V-max, and it will produce flat primers. I backed down to 20 grains for my standard load. I would start around 16-17 grains with a 110 grain bullet, and go no higher than 20. My load is giving 2200 fps out of a 10" barrel. OAL: 2.145"

Anybody have the newest updates for QuickLoad, is this powder listed?
