Reloading for Win. 264 Mag. 140gr

If you have some 140gr load info you'd share, I'd like to see it. Thx.
I've loaded Sierra 140SBT with imr4831 @ 61.3gr 3.340". That's 1/2gr over max (60.8gr) from #5 manual. Been loading it since '84. Trying to finish a 32" McGowen on a MDT chassis w/110 action. Purpose built for 140-150grs.
 
I've used that exact load for 39 years and nothing else. I haven't loaded anything for the new build yet. I do have plenty of more temp stable powders, but haven't done any load development for any and/or every bullet on new build or the 1 bought back in '16.
