Reply To: Sorting Pellets by Head Size
Ed, I’ve seen similar results in gaging H&N FTT pellets, and other cases where a tin looked great. JSB also seems to have lapses, I have first hand reports with photos like yours. Again, I offer that a good practice is to check a 10% sample apply some simple statistics. Your mean should be within 0.02 mm of what you believe is the best for your gun (typically only with sampling, test firing, etc.) and the standard deviation will tell you how likely it is that you will see outliers as you demonstrated with both (reputable) pellet manufacturers. I believe a “good” tin of pellets will have 95% within 0.01 mm of nominal. The decision of whether to sort them all is another matter.
