Looking at AMS 2431/4 Peening Media (AWS)Conditioned Stainless Steel Cut Wire Shot Section 3.8 this indicates that the weight of 50 pieces of AWS96 should weigh between 3.45 to 4.25 grams.

SAE J441 Cut Wire Shot Table 3 Weight Limits For Condidtioned Cut Wire Shot says the weight for 50 pieces should be between 3.800-4.700 grams

Which is correct?
