Been reloading for awhile but never worked up a load with no book data so looking for a little help. The load is 26 nosler with a 160 Matrix vLD bullet loaded over RL50. Looking to find pressure range as I can't find any load data on this setup. I used load data for 140 grain vld bullets to come up with what i thought to be a starting point. Using once fired nosler brass fired from my rifle fully prepped and trimmed to 2.850 with shoulders bumped .002 with federal 215M primers.
So went to my range today and setup my lab radar and shot 3 bullets
The first 64 grains of RL 50 - 2639 FPS
The second 65 grains of RL 50- 2646 FPS
The third 66 grains of RL 50 - 2628 FPS.
Weather was clear and 44 degrees
Lab radar was used for multiple other rifles with consistent readings I also was using 50 BMG powder in the 26 with the same setup as described above and it showed 50-60 FPS velocity increase with 1 grain of powder increase. Worked 3 loads from 2759 up to 2860 and haven't hit any pressure signs yet with the 50 BMG so looking promising there.
Am I starting to low with the RL 50 and that causing the lack of increase in velocity or should I just drop the RL 50 all together and work strictly with 50 BMG.
Thanks in advance - Jason
