M40A1 and MST-100 Reloading Data?

[JaneDoe]

Those of you with spec M40A1 builds using a MST-100 or Unertl 10X, what is the recipe you are using to match the BDC?

I know that the USMC has issued 173 grain Match "White Box" M118, 173 grain Special Ball and 175 grain M118LR, and I am assuming that the Unertl/MST-100 is set up for the White Box, but what is the load actually working for you?

Thanks.

Anyone want to share their reloading data?

Mine tracks great out to 1000 with 43.1gr of RL-15, in LC LR or Match brass topped with a 175

Per a friend who has this pretty nailed down...

Lapua case
43.6gr Varget
210m
175 SMK

That's the load I'll be trying in my A1 when it's done.

I once read that army loads IMR 4064. Or did at one time. I will try it when my MS 100 comes back from repair.
