Re: Powder Charge
Jimmy, it doesn't make sense that you went up a grain and went down in velocity.
Did you shoot both these loads same day?
I would shoot a 5 shot group of each and measure velocity.
I would also alternate since you are not shooting for group size but rather velocity. In other words shoot 10 shots 83,84,83,84,83,84 etc. and measure velocity on each shot.
Then I would compare results. If you do this I would like to see the results myself.
When you started seating the AB's did you have to raise or lower the seating die from where it was shooting barnes?
I wouldn't worry about the 60 fps as others have said - the AB does have a much better bc.
I really like the hodgdon extreme powders. How did the AB's & Barnes group with it?
