Weighing Brass

[hardpan]

I don't buy "once fired" range brass because I would have to sort it and I haven't a clue where it came from or its history. I try to buy Starline or better brass and let the chips fall where they may. If I was shooting for competition, I would be much more fussy. After 50 years of reloading, I can not see a high correlation of casual accuracy and normal brass weight distribution anyhow, although the Engineer in me tells me that it is there. This is because of chamber constraints to brass expansion and the gas pressure relationship.

Agreed. I only buy new. But, some of this brass is 30 years old, and I am a much better loader now than then. But, with brass as much as 20 Grs apart, or 10%, the engineer in me thinks that might be why I have fliers. At any rate, a range test tomorrow may help. My other problem is that the .300 Bee has a small blued barrel that heats up after 1 shot. So, for me to test 10 shots, I likely have a 2 hour test. Maybe longer.

Do a design experiment with the two attributes of load density (water Capacity) and velocity and find limit samples and see where it falls out. There are degrees of freedom issues but you are not write a school paper, just experimenting. It might be interesting.
