Found a sweet new load today

[Dr Pepper]

was trying a variety of loads in my 527 CZ Varmint with out great results. Then I went to the 32gr Vmax with 28gr of Winchester 748 powder. Shot 3 great groups today at 100 meters with the best inside 1/2 inch. Now to load up a couple hundred. Dr P

Nice, Did you try going higher?

Just interested because I never tried 748 with the 32's.
I've found both 35's and 39's liked 29.2gns. A touch over book max with the 39's.
I'm wondering if the 32's might like that charge also. That would be really weird.
There is another node even higher but thats well over book max. WS2 is required up there to drop pressures.

I just got a lb of Hexoganol Boron Nitride (hbn) If anyone thought a lb of WS2 was a lifetime supply you should see what a lb of hbn looks like.
I may have to test some of this combo myself this spring.

Mater of fact, I did go higher. I did 28.5 and 29gr loads, the 29 was tighter than the 28.5, but the 28 was a small ragged hole, so that is the one I'm going to load for for this rifle. FS
