My 6arc build

[mel]

just loaded up a ladder for 75g sierra flat base hp's
6 groups of 3 starting at 31.2-32.2g of 2000-mr in .2g increments

no published load data for 75g and 2000mr but looking at 80+ g data i know max is 31.5 @ 80g
and 30.6g at 90g bullet
and 30.3 at 95g bullet

so safe to assume max with 75g is right around 32g

im going to shoot theese after work tommorow since i open i get out early in the day

forgot to add coal is 2.110 and im touching the lands
