Shot the first 6x47L that I chambered this weekend. Shot 55s, 65s and 100s- 9 1/4 twist so no need to try the VLDs. I used Varget for the light bullets and 4451 & 100V for the 100s. This is a 24" featherweight barrel on a Savage so I didn't expect much for accuracy but it DEFINITELY is not up to 243 Winchester velocities. I went until I had definite pressure for each bullet and powder so I would have a baseline to work off of since there is almost no PUBLISHED data on this cartridge.
Wind was horrible so groups were not always great-even with the good rifles. If you guys are getting 243 velocities, you are also getting stratospheric pressures!
