This may be academic, but I'm wondering if anyone who weighs lead (unjacketed) bullets uses any other tolerance aside the SAAMI spec (which I think is +/-1.5% for bullets >100 gn)
I took 3 100 piece samples (240gn LSWC) from different manufactures and compiled the following data which was about the same for all 3 groups:
100% pass - SAAMI tolerance of +/-1.5%
86% pass - +/- 1.0 %
40% pass - +/- 0.5%
I'm still trying to correlate both accuracy & precision to this type of screening (in a hand gun anyway) and I'm wondering if anyone who uses these types of projectiles has noticed improvements in screening for higher tolerances.
