how much is 10 thou
the question i have is this. if i insert a projectile in a blank shell and close the bolt on my rifle to push the projectile in to touch the lands and my digital calipers read 2.794 inches. as i am not very engineering minded what length should i have to give a 10 thou jump? also is 2.788 a 6 thou jump? thanks in advance for any info.

1 "thou" is 1/1000th of an inch. To put it another way 1mm is 40 thou, so 10 thou is a quarter of 1mm.
You are correct, if your overall length with the projectile touching the lands is 2.794", then 2.788" is 6 thou less - giving you a 6 thou jump. Therefore an overall length of 2.784 would give you your 10 thou jump.
