Anyone tried this combination? Results? Did not find info in the 6x47 load section. Help will be appreciated.
6x47 Lapua loads with 115 dtacs and H 4831sc?

Well not quite the same combo. I do shoot 115 DTACs and find that for my 6X47 Criterion 1:7 barrel, the load for 105 Hybrid and 115 DTAC is just about the same, 39.0 and 39.2 respectively with H4350.
I had 3 pounds of H4831SC left over from my 260 Remington days so I thought I would use it up on my position practice loads. So I did do a full workup of pressure testing from 39.0 to 42.0 in .5 grain steps using 105 Berger Hybrids. Found no pressure point. Primers were not showing any undue flatening. The groups I shot for each powder step showed 39.5 had a group of .347, 40.0 had a group of .380 and 40.5 was .365. By 43.0 the groups were .735.
I choose 40.0 as my new test load with 105 class bullets. I never loaded any DTAC's because I save those for competition but I did try this same load on Berger 108's and they shot 1 group around .5 and the second around .6. All loads were loaded .025 off the lands.
I hope that helps a little. This load also gave me the same POI at 100 yards as my 115 DTAC load but I don't have any chrono results because I am never going to shoot this load beyond 100 yards as practice.
