I have 4", 6". 12" and 24" calipers and Mics from 1" to 6". I made a living with them for years. Measurement isn't the issue. The "quick" question was what the majic minimum O/A length is. I want to check each of my rounds. The ones that I found set back I'll discard and the others I will test fire at paper. Haven't fired a Winchester Ranger through my weapon in years and would like some confidence that it will still feed them. (That's our prescribed/designated duty round and we cannot carry anything else.) I'm a IL certified firearms instr. and put 3-400 through my weapon every other week. Dept. furnishes WWB for training. Thanks to all that replied. I'll head down to my cop shop tomorrow and pick up a couple hundred Rangers.
