The lines of the throat are consistent with SAAMI. SAAMI tolerances are -0.00" to +0.002" while PTG uses + - 0.001" for the tolerance. In theory, this would mean that half of the reamers produced would be smaller than the SAAMI spec.
In reality, the propensity to cut tight chambers means that a larger fraction of the throats end up being too tight.
Has anyone pointed this out to PTG?
