Its been on my to do list to do some accuracy testing based on the type and quantity of lube left on the inside of the case neck after sizing. I see a wide range of ideas and methods so I figure I need to test it for myself.
I'd like to test several options such as, clean necks after ultrasonic cleaning, wet SST media, tumbled with a few different dry media, and wet and dry lube right after sizing. I also want to test freshly loaded rounds vs. rounds left to sit on a shelf for a few weeks.
Since muzzle velocity will probably be the biggest tell in this test, what sample size do folks on the forum use for gathering this type of data? 5 shots, 7 shots, 10 shots +?
