Pretty new to tuning rifles. Looking for a little advice on my plan. Would you do anything differently?
Would like to get this rifle down below half minute accuracy. Wouldn't be opposed to getting it to .1 or .2 - rifle shoots awesome without much trying, so I think it has a lot of potential.
I did pressure testing the other day. No hard bolt lift, no primer issues - only slight flattening, no extractor mark. I think I'm hitting case capacity of my creed before max pressure. 26" Kreiger barrel with a TBAC Ultra 9" can.
The bullets are jammed hard for this pressure test. I'm thinking of coming off the lands ~.010" and shooting two shots of 41-44 grains in half grain increments at 730 yards (could go further distance if advisable) and looking for the best vertical grouping (ladder test).
Hopefully that shows me a window with a good vertical. I will then take the charge at the center of the best grouping and try seating depths .010, .020, .030, and .040 off.
From there, fine tune powder charge in .2 grain increments.
Finally fine tune seating depths in .003" increments.
How does that plan sound?
