Weighing brass?

[wisconsinteacher]

Well I would like to start working up a new load for my 22-250 . This time I want to make sure I am getting loads that are very close to each other. This is the first time I have ever put brass on a scale. Out of 86 pieces, I get a range from 151.4 gr to 155.0 gr. that is a difference of 3.6 gr. My question is should I cut some of the brass out of my stock and get the total difference from lightest to heaviest smaller or am I okay? Of the 86 pieces, I had 19 at 152.7 gr and 65 pieces that were within 2.6 gr of each other.

I only use brass that is within +/- 1 grain...I keep the brass that is too far off until I have enough to load a batch using only the heavy or light brass...works for me anyway...I do the same for bullets.

I go by + or - 1% of the average rather than a certain grain. If you use 1 grain to cull brass you will cull a lot more smaller cases like .223 & .22-250 than you will larger cases such as .30-06 or the magnums.

Your average is 153.2gr and 1% of that is 1.53gr.

If I go with 1% of the average, I only have to take 8 pieces out of my lot of 86. I can live with that.

Try it and see how it works. You can always cull more later.
