Don't have a milligram scale. Used digital calipers took five measurements of each averaged than and got one prill measuring 0.384mm the other 0.336mm
Milligram scales won't get you close enough for realistic measurements. You need a microgram scale and those are dang expensive. You're talking about north of $5000.00 for a good one. Hence, send it all off to a certified assayer.
