I weighed them with a SHIMADZU UW220H lab scale at my job. This is what I got in grams and Cal. to grains. This scale is enclosed so air will not affect the total and I tiered it for each pellet.

Note: the skirts on the Raptor’s are not right. They are not straight or level. So here it is

Crosman Premier Domed 14.3gr (.22)
1-.927g=14.305gr

Although the PBA's seem tight. It's funny that some of the heavy pellets actually come out on the light side. You may not think that weighing .8 light is a big deal, but that's almost a 10% error in some cases or -1.44 FPE at 900 fps. You can go from 15 FPE to 13 FPE simply by changing brands!

Keep up the good work!

What, me worry???

I have a decent scale so no surprises here. This is good stuff because a lot of people just don't do it and need to see how bad some of these pellets can be. I don't think a variance of +/- .2 grains for an 8 grain or +/- .4 grains for a 16 grain is too bad but some of them are unacceptable.
