I am looking for 300 Win Mag 180g reload data for N165 and N160, specifically for Accubonds. I have quickload and worked up some loads last weekend that did not shoot well. I did a pressure test run up for N165 to 78g without seeing any issues. I worked up some loads from 76.4 to 78g in N165 and headed to the range. Got to the the range in some hot weather 85-90* and had some heavy bolt lift right out of the gate and best groupings were 1.3moa. Velo ranged from 2975 to 3088 which was a little more than predicted in QL for my barrel length. Vihtavuori does not have 180AB on their site, but show 70.4-76.4 for N165 in NB180s. Way well below pressure max which seems low. They dont show n160 at all for the 300win. Old VV reload has N160 listed for 180s but the charge for N165 is also way hot compared to this years released info so not sure if there was a formula change in past 4 years.
Anyone have some preferred loads for Vihtavuor N165 and/or N160 in the 300winmag 180s? N165 in my 280AI 160AB are lights out sub .5moa and shows some promis in my 338LM...
