Dear shotpeener,

I have to verify something about AMS 2430 M.

According to the shape maintenance requirement of cast steel shot, the allowance of "Marginal Shape" is removed.
Shall "Marginal shape" be included in "Unacceptable" or "Acceptable" ?
Please let me know the instruction.

Thanks,

AMS 2430 M does not contain requirement for marginal shapes. This term and drawing was deleted from revision L and does not appear in version M.
However, if you do refer to version L drawing figure 1 you would group the marginal shapes with the unacceptable shapes as criteria for rejection in version M.
