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?

Re: Powder Charge

Had you cleaned the rifle before shooting the NABs after shooting the Barnes? Could have been due to the Cu from Barnes left in the barrel causing the problem too.

Re: Powder Charge

Thanks for the response.I was not trying for groups,just experimenting with powder charges to see if I could get to 3195 fps.Every load that I have shot at or close to that velocity has grouped very well.The last two times I have loaded with Ramshot Hunter with excellent results.The word is that Hunter is temp.insensitive like the Extremes.No way to tell when it is 103!My load of H-1000 has been great and super consistant with the 168 TSX.

Re: Powder Charge

Yes,I always clean when changing bullets and/or powders,plus I fire at least 3 foulers before getting down to the nitty-gritty (same load as the testing is going to be done).
