jeffbird, I found the exact same max for Superformance with a 127 LRX before they made this available. I used 6.5 Creedmore data and started low for 130 grain bullets in the Hornady Manual. I had the powder and really wanted to give it a try and the case volumes were really close at that bullet weight. Turns out 46.5 gr Superformance with a 127 LRX is right where my Savage model 11 likes to shoot.
