It's been a long time since I used the 125 gr PT but used IMR 4350 at the time with good results. I use a lot of 129's and 130's now and use H 4350 and IMR 4451 for those with good speed and accuracy. I probably should try the 125 gr PT again, it's a really good bullet.

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 59500 psi, or 410 MPa
or a maximum loading ratio or filling of 110 %
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 !
7 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

IMR 7828 ssc has been great for me in the 260 Rem with 140's, probably should also try it with the mid weight bullets based on that. Ditto for the 6.5x55. For some odd reason H 4831 sc has never given me the speeds it should, not sure why since it should be good. The accuracy has been good with it though. The 4350/4451 class of powders has always given both good speed and accuracy in both rounds.

I had great luck with IMR 7828, but it was with a interlock 140
