Just got around to trying rl26. 105hpbt.

At 49.5.gns. I got 3208 fps. 1" at 100yards.
49 3155 fps. .665" at 100 yards. Coal was 2.765".
I'm sure once I get the rifle cleaned and in a touch less wind it will do even better.

But 3155 in a 22" barrel. Is more that I was hoping for.

Pretty sure that 50 grains would be about max.
I am using GFL brass a guy may snag another grain or two room in some Lapua and pick up 50 or 100 ft.
