Has anyone used Vihtavuori N560 for 243 or 6.5x55
Hi Sikaside, have used the above in both calibres.
6.5x55 Hornady 129 grain bullet. have loaded between 46 and 49.4 grains N560.
.243 Sierra 85 grain bullet. loaded with 45 grains N560
.243 Sierra 100 grain bullet. loaded with between 44 and 45.5 grains N560
These all gave good accuracy with no pressure signs. However, consult the Vihtavuori manual and work up a load for your rifles. Mid range usually gives the best accuracy.
