So, I have been trying to develop a load with some Starline brass I had laying around in 6.5 Creedmoor and H4350.
Last range day was a desaster so I redid my load and put Excel to work.
I think I'll try 41.1gr of H4350 and try different seating depth. I did 2 run of 0.1 increment and I thing my Chargemaster 1500 might be off a few pellet sometimes.
Here's my Excel I did, for some pointers:
- SD/ED 1-3 = from run 1, +-.1g (3 loads)
- SD/ED 1-5 = from run 1, +-.2g (5 loads)
- SD/EDmoy = means from Run 1 and 2
- SD/ED-3/5 = From Run 1 and 2, .+.1gr or +-.2gr (6 or 10 loads)
The best SD-5 and ED-5 is 41.1gr
