I have lots of data....mainly for the 140+ though, and my barrel is a 30" 8 twist. H4831sc was fantastic with the 140 VLD's, a tad slow but stupid accurate. Reloder 26 did everything well, as long as it doesn't get terribly hot. Around here we max out around 80-85, usually hunt when it is teens up to 60-70 or so.
Here is some data for you. Of course, same ol warning, work up, start lower than data I list, don't be dumb and start with a max load, yata yata yata.....
4831sc load -
Lapua Brass
CCI BR-2
47.8 H4831 SC
140 VLD seated .005" off
2930 fps
Shot in the .3's consistently. Max was around 49.0 or so if I recall, going just a shade over 3000 fps.
Reloder 26 load work up. This was working at the top end of pressure, max was around 50.5 grains. Also used a 6" drop tube, and shot this at 65 degrees -
Lapua Brass
CCI-BR-2
Reloder 26
140 VLD
Seated .005" off
3 shots each -
49.0 - 3044 avg 7 fps e.s.
49.5 - 3053 avg 13 fps e.s.
50.0 - 3107 avg 12 e.s.
50.5 - 3134 avg 9 fps e.s.
51.0 - 3137 avg 19 fps e.s.
After doing a ladder test at range, I settled on 49 grains. It was easy on my brass, and my 500 yard group had under 1" of vertical spread and was only 1.75" for 3 shots. Plus, 3045 fps with a 140 is nothing to sneeze at.
After that I moved on to the 147 eld-m for a season, and was unsatisfied by terminal performance. Now I have my final load that will remain unchanged until I burn the barrel out, and that is 49.0 grains of Reloder 26 under an HBN coated 156 EOL going 2940 fps. Max was right about 50.2 grains going 2980 fps. Using Peterson SRP brass and CCI 450 (small rifle magnum) primers. They are seated .065" off to fit in my AICS ARC mag, and they don't seem to care about seating depth.
Not that it matters, but out of curiosity I tried H1000 just because. Using a 6" drop tube and settling as much as would fit in the case with heavy compression and without pushing the bullet back out, I still didn't get any pressure signs, but probably close. Maxed out on capacity at 2950is fps with the 147. Reloder 26 got it up to 3040 fps.
Hope that helped a little. Take care!!!
