Grading a Caliper

Like most things involved with precision reloading my opinion is precision is more important than accuracy. I use my automotive feeler gages to check my calipers. Works good enough for me but then I am a 195 - 197 shooter not a 199 -200 shooter. If a base to ogive is .00110 or .00099 will it redally affect my shot that much at 1000 yards? Every shot erodes the throat a little, does anyone do a new seating test after every match and chase the throat?
 
Maybe a decimal error there,
"If a base to ogive is .00110 or .00099"
that's +/- one tenth.
With Calipers?
.00110 - .00099 = .00011 or eleven ten thousanths according to my math


Point is all the precison in the world at the reloading bench won't help wind calls or improper follow through. Wind reading and range sessions to work on technique requires is a lot more work than pulling out the credit card
 

Jackie's comment is spot on!

Calipers are great for quick measurements within a thousandth or two. Good for short, or small diameters. Bigger diameters, or llonger length need 8 inch or 12 in calipers etc. Most use calipers , because they will get close measurements, in many different lengths, diameters, or depth. Replacing micrometers of different sizes.

Learned how to read Vernier calipers & 6 / 12 incn scales when I was 14 or so. Same way with standard micrometer. Along came dial calipers, never saw digital measuring equipment till aircraft work.. Only reason they had digital equipment was for the younger generations, that could not read standard micrometer or calipers.

Only reason for me today to have digital anything is I don't trust my " OLDER " eyes.

To all a good day!
Man do I know how that is!! Went to digital when my eyes started going. Welding can be rough on the old eyeballs!!
