Very similar book performance to TAC and a reputation for extreme temp stability (TAC may be very stable too, I don't know for sure). I received a response regarding my email to Alliant about the Power Pro powder. It is 2000MR, and he said they don't have any loads for the 338 Fed and are working on getting it to market. Don't know where the loads on Loaddata.com came from.


Look on page 89 in the link below. It's from the Alliant website. A 225 gr Fusion at 2600 fps looks really promising.

I loaded some 200 SST and 200 Interlock with TAC. I'm trying them this weekend. I stopped trying to find a load for the 215 Sierra when I couldn't get it to expand on water jugs during bullet testing. It hit water jugs at over 2400 FPS. The bullet on the right is a 200 gr Fusion. It expanded nicely and weighed 167 grains. It was going muzzle velocity and expanded nicely without over expanding.
