pelletgage

just received pelletgage in .177 , makes me wonder just what tolerance range the makers set for good or rejects IE: one tin of quality pellets had 4.49 to 4.54 and everything in between in the same tin . Tin was marked 4.52
Now in defense i have been shooting this same batch for several months (from the tin ) and have not noticed any strange flyers from a Daystate Pulsar HP .177 set at 19 FPE
