To answer your question a bit more in depth.
I used to weigh pellets a few years ago, lets say a tin of JSB 8.44grain.
Anything between 8.38 and 8.50 I would use only for competition use, anything outside these weights I would just plink with.
I then did an indoor benchrest test with the heaviest and lightest of the batch. 8.27 being the lightest and 8.62 being the heaviest. The difference in POI was negligible, that's why I don't weigh them anymore.
By all means do it if it gives you confidence, but personally your time would be better spent drinking beer. Neil.
