Thanks

Pm if you need a 250 go I bought one accidentally. Mine does measure slightly different than my 22-250 guage but it aint much. I will remeasure it tonight for curiosity sake.

I have to respectfully disagree with JGS. SAAMI gives headspaces:

22-250 as 1.5749 - 1.5849 with a shoulder angle of 28°
250 Savage as 1.5792 -1.5892 with a shoulder angle of 26.5°

Both use 0.347 as the datum for HS measurement.

If you do the trig, the two gauges will measure a difference of 8.5 thou on the same chamber or vice versa.

JGS 22-250 = #0028
" 250 Savage = #0037

Sorry, I misinterpreted what you were implying.

#28 is for a 6mm/22-250 and #38 is for a 6mm/250-3000 savage- 2 different parent cases
