Tweaking bandloads - 08/16/16
I'm working with 3 rifles at the moment. 2 have been easy and used long established loads ( 308-varget-165s; 270-h4831-150s). My 06 is in need of some load tweaks. I'm trying to decide the order to start without shooting a 100 bullets.
Tweaks I've used in the past include (and in order of usage)
Vary bullet seating depth
Use different primer
Use different bullet
Use different powder
The last 2 are more drastic than the first 2.
My gun shot 1.4" to 2" groups (gross measurement). They aren't horrible but do measure more than I was hoping to get to a starting point. I'm looking at picking the 2 best groups (180 PT-58.0 H4350 and 180 AB-59.0 Hunter) and playing with the seating depth to see if groups shrink. My goal is a repeatable 1" net group size (1.31 gross).
Before I start cranking out a bunch more handloads with tweaks, wbat have you guys found to be the most influential tweaks to consider and/or start with?
FYI - gun has been bedded, trigger tweaked, barrel free floated, may box 'free floated', etc.
