I have a bunch of allegedly once fired brass, sorted by brand. Is there any reason these should not be used for a ladder test after full length sizing as opposed to once fired brass I bought new and neck sized?
I'm thinking... why waste the bullets to fire form and then test if I don't have to...
Thanks
Mike
Just to get things started, I would say use the brass you have. I'm guessing that you are developing a hunting load or you would have acquired some quality brass and screened/sorted it by weight, volume, length, color, sheen etc.....:rolleyes:
It's usually better to develop a load with fireformed brass but you will get workable results with your non-fireformed brass. You'll just have to fine tune a little.
I kinda thought so, I'm just looking for nodes here, and will compare 3 shot groups within a node once I narrow it down.. Thank-you!Quote:

I would discard any rounds from the test that have high neck tension.
How can I tell that? Use a crony?Quote:

THANK-YOU! Just had an "Ah hah" moment... if the used brass is old, and worked more, it gets hard, and will give a different neck tension because of the lack of plasticity!!!Quote:

Correct. If you have the tools to check variations in certain dimensions after sizing like base to shoulder and outside neck diameter, that will tell you when you need to anneal.
