Thread: 7 SAUM initial charge weight.

I'm after some input about a starting charge weight for a 7 SAUM that was recently put together.

It's been chambered to allow for seating projectiles further out of the case.
When seating 162 eldm's -0.030" off the jam point, the COAL is 3.045" and the BTO is 2.263".

I've got some ADI 2217 & 2213sc.
I'm looking to start with the 2217, and I'm just not sure what charge weight to start off at, given that the case volume is larger due to seating out projectiles as far as I am.
Barrel length is 20".
