Sounds very short for a 30-06. I have yet to see an '06 with a distance as you have measured (with a COL) shorter than 3.250" But.....anything is possible. FWIW you are measuring the COL, not the distance to the lands with your method. When marking your stick with the bolt closed, was it cocked? If not, you will be short about .035" because the firing pin sticks out of the boltface. This would increase your actual COL to 3.345", a realistic figure. Regards, Eagleye.
