Hey guys,
I've been sorting brass by manufacture. I'm not a bench rest shooter, just a guy that works real hard at getting the best out of my loads.
The question is,
I have Winchester, Federal and Nosler .204 Ruger brass and it is all sized, prepped and trimmed to the same length. I measured wall thickness and weight on three of each and listed the average below.
Nosler case thickness .0100 and weight 98.3gr
Federal case thickness .0125 and weight 95.4gr
Winchester case thickness .0105 and weight 95.5gr
Nosler the thinnest wall however it is the heaviest, it must have a thicker head. Federal is the thickest but it is the lightest. How do these small variations affect accuracy?
Can it be as easy as adjusting the charge for each case type to achieve best case results?
Is this really necessary?
I'm guessing you would have higher pressure in one case so how much would that affect velocity?
Is any of this really an issue at all?
Thanks in advance for your response. Real data would be appreciated.
