I have been testing my first 6-6.5x47 over the last couple of weeks. I've experimented with H4350, Varget and RL15 with 105 Berger Hybrids. It has taken more work than the other cartridges I've developed loads with. I can see from the data on here that I'm running quite hot loads compared to the average load used. The cases are handling the pressure but I'm considering whether the higher charges are affecting accuracy in this case (pardon the pun). I've tested the following quite extensively with 105 Berger Hybrids and CCI 450's 0.020" off the lands. H4350: 40-42.4 (42.0+ hot) RL15: 36.6-38.0 Varget: 35.2-38.6 (38.2+ hot) Plus I've then gone on to tune stability nodes with OAL but have rarely seen better than 0.3 MOA despite extensive testing. This is very unlike my 2 previous 6.5x47's which tuned very easily with big wife nodes produced high levels of accuracy with brief OAL testing. Accuracy/stability nodes have been noted at the widest with Varget and H4350. I have at this point I am wondering what accuracy people have discovered with theirs compared to proven high accuracy cartridges. People talk of the cartridge being 'fussy'. Is it fussy in that it's harder to find a good load or that the accuracy doesn't tend to match that of say a 6BR or Dasher?
