I hate asking for QL help again, I really should invest in the program for myself one of these days.
I have a rifle that I need to get working with again. 26" barrel 1:7 twist Savage that I built. I have the DTAC and Berger 115's on hand. Powders I have are RL22, PP4000MR, I&H4350, I&H4831 and SC and H1000 on my bench. Berger sent me their data but it doesn't list PP4000MR which has a burn rate in between I7828 and RL22. I just need a starting point with these powders and both bullets kind of like this data Dr Mike gave me in another post.
Thanks!

Useable Case Capaci: 40.423 grain H2O = 2.625 cm³
Cartridge O.A.L. L6: 2.515 inch = 63.88 mm
Barrel Length : 22.0 inch = 558.8 mm
Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 50000 psi, or 344 MPa
or a maximum loading ratio or filling of 107 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
USE ONLY FOR COMPARISON !
2 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.
