Powder Measure or Scale for hunting loads?

[skb2706]

I got a lot simpler formula than that.

Total number of rounds used per year hunting big game....in a great year, one state may total a whole 10. For this I will hand weigh each one, how long can that take ?

For everything else it depends on the powder. For loads that take WW748, RL7, AA1680, H380 and the like I do not. I will weigh one every 10 or so.
For extruded powders like IMR4064, 4350, 4895 etc. I will weigh everyone.
