Thanks ny, and thanks brinky, it's good to see a quickoad run as another data point, not a lot out there to go on.
I would've guessed a few grains less than your top-end load of 64 grains R-26 and the 162's, based on everthing else I've read.
I've got a box sitting on the bench, waiting. Have you shot any game with the 162s yet?
That is a top load and it’s Moly coated and the bore is also coated so do work up carefully. If you are working with non Moly’d bullets and a non coated bore you will get pressure much sooner. just moved to the ELDX’s from AMaxes. Same load with the exception of the bullet. The AMaxes hammered deer and they either dropped right there or within a step or two.
I like QL for powders not traditionally listed for certain cartridges. RL 26 is one of them. The 280 AI isn’t enough engine for 26 in most people’s minds but it seems work.
