[QUOTE="MooseChaos, post: 2109822, member: 117474"] With this powder I'm more concerned with undercharge than overcharging. With 4895 I've gone as low as 70% of full blown with no ill effects but H100v is unknown to me as far as reduced charges are concerned. I'm thinking about going with a load equivalent to what I'd use as a starter in my 7x57 then step up as possible. Alternative is using the 7.65x53 load data for 4350 & 4831 - averaging them and reduce by maybe 5% for a starter. I found it interesting that the Argentine round that has less capacity and can be used in the much weaker M91 action as well as the 1909 M98, yet still has slow powders recommended. Looking at them I think I can safely start at @46 grains/lr primer/150 Hornady sp and work up. The 8mm has more base to push against so equivalent pressures should be lower, H100v is slower than 4350, and the action is as strong or stronger than the Argentines. Thoughts??? [/QUOTE]
