After a couple of recent threads I decided to revisit the weighing of pellets. Currently I am using JSB Exact Express 0.51 grams (7.9 grains..?? my scales say 7.8 grains) Batch # 36004910 4.52mm So.... after some hours of weighing two tins of 500 (1000 pellets) I ended up with three weight variations 0.50 grams - 131 pellets - 13.1% 0.51 grams - 750 pellets - 75 % 0.52 grams - 119 pellets - 11.9% I then went to the range and used these weighed pellets at 30 yards - my zero 55 yards At either distance I had no discernible POI shift with any of the three weights. Conclusion: With this batch I don't need to weigh them, use them straight from the tin. When I get a new batch I will probably sample two tins, to see if there is any large weight variation.
