[QUOTE="MNbogboy, post: 827259, member: 18849"] Bart & Pieter, Yes, if external dimensions are exactly the same and the brass has the same density then weight sorting is perfectly accurate for volume only... Weight sorting is my method of choice but obviously not fool proof... One variable not affected by fire forming is the rim/extractor groove...This is an external dimension controlled mainly by manufacturing processes as mentioned earlier and normally not affected by fire forming... Therefore any addition/subtraction at manufacturing to this area will affect case volume and/or internal dimensions if the case weight remains the same... As Bart mentioned even barrel/bolt alignment could be a cause for erratic case weight/volume relationships... But this also would affect the external dimensions of the case and obviously skew test results. Also mentioned earlier was the fact that "cheaper" brass may be suspect to quality issues...I have had brass in the past that would not even slide into a shell holder...My guess would be that these areas may or will not be totally uniform in some or any cases (no pun intended). For the above reasons case volume sorting alone nor weight sorting nor a combination of them both may not answer every problem... There will always be the possibility of two cases weighing the same and with equal volumes that shoot different... We can only speculate that maybe the distance to the primer may be different or even the internal shape of the charge is different, most likely due to differences at the rim/groove... Food for thought, Randy [/QUOTE]
