I've read that PP 300-MP is a slightly slower version of H110/WW296. I am interested to know if anyone has used it with 300+ grain bullets in 20 to 32kpsi 45 Colt loads, or if loading data is even available for such. Brian Pierce published some jaw dropping data for "Ruger Only" True Shot 360 grain WFN bullet. However, I have been unaware of any other 300+ grain bullet 45 Colt data. Thanks
Matt

One of my manuals shows some amazing velos for this powder. I've not bought or used it yet. It's never a bad idea to contact the maker with questions, though likely you'll get SAAMI answers.

I'm guessing the pressure at 25,000.   |

It seems to be a great powder for 357 magnum. Looking in the Hornady manual for use with XTP's for example in 158 grain it shows 150 fps higher velocity than W296/H110. It also shows 100 fps faster with the 125 gr XTP's than 296/110.
In 44 magnum it hangs with 296, H110 and AA9 for 240 and 300 grain XTP's.
These are loads I use a lot, so they are what I recall comparing.
