Will get back to it this afternoon, I need to go pick up some fish this morning for my pond. The lessons I've taken from all the shooting up to this point are:
- The brass, 30-30 Win or 32 Win Spl, doesn't matter. In fact, both being of Winchester headstamp, they are identical after several full load cycles. All the dimensions are identical; volume, lengths, and thicknesses. The best case length I can hope for is 2.020". With that said, 30-30 Win brass is plentiful so that is what I will use.
- Quit the Trail Boss 110-grain bullet fireforming cycle. This has formed the case but not to the degree that a full load will do. Might as well use whatever load I come up with with the first cycle of any brass. My bet is that accuracy will be the same with a little loss of velocity. Some of this is coming from my experience with the 303 British. This step will also save one cycle on the brass.
- Bullet neck tension is probably more important than concern over bullet jump. I'm keeping the seating depth at a full caliber (.308") for the next round of testing
- I mounted a new scope on the rifle in order to see if the old scope had a hand in some of the shot to shot shifts in POI had anything to do with the old scope.
