These both come with different batch numbers to give you even more variation to select from.
Once you have found a pellet you are happy with buy as many as you can get your hands on while you can, in a years time that die number and size may be hard to find.
If weighing them or any other form of preparation gives you more confidence then do it. I have done this myself and you do find some extreme weight pellets, whether they would cost you points is debateable.
I would recommend using a pellet box that protects the pellets from damage. Take half a tin of pellets in and out of your pocket a hundred times then examine them with a magnifier, the damage is quite bad!
So fill you pellet box and leave the tin at home.
As Simon says really.
One other thing i do to protect my pellets is by keeping the foam pads that are in the tins and cut them so that a tin is completely lined with foam...sides, top and bottom. Pellets don't get damaged in transit when you have half a tin.
