load dev sierra 75g flat base HP & 2000-mr

[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

gas gun data
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
