weight VS volume in charges
I've had two IM's asking/wondering if there is a benefit of weighing out powder charges on a scale instead of depending on a standard powder measure.
This is just my opinion but I have had better accuracy with weighed charged over volume measured charge. Now we are not talking a couple inch difference in the groups, simply a little tighter group and a more consistent tighter group with out the flier so often.
If you want to shoot weighed charges here is how I do it. I sit down with my collection of small plastic specimen cups. Then I take a powder measure and set it at say 100 grains. I pour out fourcharges into cups and weight each of those charges.
So I will now do Goex 3f to maybe explain, and I have set my electronic scale for grains. The scale tests true before any weight is done. I try and pour the same amount each time into the powder measure by volume.
100 grains by volume = 94.4, 96.4, 94.8, & 92.8 grains by weight
this has an average of 94.6 grains by weight. So if I wanted to shoot all charges by weight, I take my plastic cups and weigh out 94.6 grains of Goex 3f from that can,by weight, of as many charges as I want to shoot.
Remember each powder can be different in weight, and each grade of powder can be different. Also each time you open a new can/pound of powder re-do the entire process.
