Trashy have you had a chance to try out any of your loads, I’m also looking at the 95sst as a possibility. Also any ladders from there on up...
Here’s a thought.... I looked at the hodgdon reloading mag, for the Grendel, and compared the 107 Sierra with the 95 sst. Powder for powder when both had that powder listed, the lighter bullet was +1gr powder up on both the low and the max load ends. So if all you knew was the loads for the heavier bullet... the bottom of the lighter one would be 1 gr up from the min of the heavy.
Heresy I know...
