brass weight

[tvc15]

 Question, All my powder and bullets are same weight. I can understand different weights for different brass, but I have a 3 grain difference in 20 rounds of winchester brass. The brass is not from the same batch (some is range stuff) but I trimmed all to the same length! Can it vary that much?   TVC15

Yes! Buy a 100 round bag and weigh them ,you'll be surprised at the difference. different lots and different brands will show weight differences also.

You also don't mention what caliber. Larger calibers tend to have a larger difference in weight variation. But, a 3g difference is a very small amount that most guns let alone shooters would not see a difference in accuracy.

It is a .243 cal. Also loaded some .270 and measured almost 10 grains between 20 rounds. I may pull these and weigh brass before reloading.  TVC15
