[QUOTE="Dragoon300, post: 2092261, member: 115285"] It depends on your caliper and your familiarity with using calipers to get precise measurements. The feel can be tricky at best, and hard to confirm .0005" (1/2 of one thousands of an inch) micrometers are much more precise, but specialized and costly. Gage pins can be gotten in an array of sizes. I recommend getting gage pins from .002 under the desired size to .002 over the desired size in .0005 increments. These pins can be had for $3-$5 each. They are round and on size, when you insert one in a case if it is primed there will be a slight pressure and when pulled out a suction if you are within .0005" and the next size pin does not fit. Calipers are quick but not necessarily accurate to .0005" [/QUOTE]
