Some good comments here! I'd like to add that volumetric measuring can vary too. If you set five or six measures at a given charge, say 90 gr. of any given BP, and then weigh them, you will find that they vary by as much as 4-5 grains in the actual charge they throw. So for accuracy at a match, or longer hunting ranges, be sure you use the same measure that you used to work up the load.
And if you want the best accuracy, you must pour the powder, and "shave" off the top with either the pivoting nozzle or a straight edge like the back of your knife just the same each time, while holding the measure vertically.
You should also roll your powder can over and over with your hands before you start to pour from it, if you travel at all getting to shooting spot or match, because vibration will gradually settle the "fines" to the bottom. If you don't do that, your powder is getting stronger and stronger in effect (from a given volume) as you get closer and closer to the bottom of the container.
