When discussing weighing bullets and podwer, you usually see someone throw out a tolerance of +/- some weight, say +/- 0.5 grain. But the more I think about it, the more I wonder if +/- some percentage of the weight wouldn't be more useful? The way I see it, +/- 0.5 grain of bullet weight would make a lot more difference to the guy loading 55gr .223 Remington than it would the guy loading 405gr 45-70.
I'm thinking the same would apply to powder measures. I've seen guys who say they are satisfied if their powder measure drops +/- 0.1 gr. I'd think that would be excessive on 5 grains of bullseye but probably being too picky on 40 grains of 4895.
So what do you guys think? Maybe +/- .25%? For my 30-06 loads of 26 gr of RL-7 under a 185 gr bullet, that would give me roughly 25.9 to 26.1 gr of powder and 184.5 to 185.5 gr on the bullet. That doesn't seem unreasonable. As a matter of fact, it may be a little too restrictive. So again, what do you guys think?
