would like to hear any data on this bullet in another cartridge: 6x47 Lapua. I'm in same camp otherwise as Parshal. These look like great bullets.

Planning on running them in 6 creedmoor. Rifle isn't ready yet though. The charge weights seem to be pretty close to the 105 loads from what little I have seen so far. Not a lot of bearing surface on that bullet.

I picked some up to try out in my 6slr in the next week or so. It shoots DTACs well, but would like to have something else worked up in case I can't find the DTACs.

7.5 twist barely squeaks by according to Bergers twist rate calculator,,,2000 ft elevation figured in @2925fps.

Would this bullet do well in a standard .243? Would using heavier bullets with slower MV help add a bit of barrel life? I know it is mostly up to the rate of fire but wondering if slower heavier bullets would make any difference.

Should work fine in a 243 as long as you have a fast enough twist to stabilize them.

It's debatable but heavier bullet moving slower would most likely not get you better barrel life if they are ran at the same pressures.
