Alpha Brass - More Powder Tests - Worth My Time?
Well, I thought I would take the time before the PRS season starts up again to see if I can find an even better powder charge for my new Alpha brass. I loaded up another 3 charges and tried some 10 shot groups with them.
Numbers are pretty good. This is still new, unfired brass. So this is also my fireforming shots. I am thinking I will probably need to do a little fine tuning after I process this all. Anneal, size, mandrel. My Lapua loads had changed a little after that. I'm not sure if it was because the brass was processed and changed slightly, or was it just my barrel needing to be cleaned, lol.
I have more testing to do, I think. But, I would like your thoughts!
Am I wasting my time with these tests? I still want to get all my 200 pieces of brass fired so I can make them all the same through my process. I don't know if I should do a few more powder charge tests, or just call it good and pick one of these.
It seems to me, all of my groups at 39.1, 39.2, 39.3 and 39.4 grains are making plenty acceptable groups on target for my PRS needs. The speeds are slightly different, but not up to the same as my Lapua load at 39.2 yet either. I am still new, so any input and thoughts on this would be appreciated! I want to get a good, dependable loading figured out in the next few weeks so I can make up a lot of rounds to be ready for the first 2 matches when they start back up in September!
I still have a few weeks to get ready, but I am trying to get a little ahead of the crunch time. I can keep going up and see when I hit 3000 fps, I notice that over 3000 my groups open up a lot. But staying just under seems to work well for my barrel.
I kinda want to keep going until I find the charge that gets me at 2990fps, so I may need to just keep going and find it.
Or, I could be wasting my time.
Please let me know what you think!!
I appreciate you watching and any input you have to share with me!! Thank you for spending some time with me, and have a great day and an awesome weekend!
