You learn something new everyday. Having ordered projectiles from online dealers in the past I never thought to count them. That all changed when reloading 500 7.62x39 AK rounds and I came up 20 bullets shy. Needless to say I started counting them and to my dismay I found that my orders were coming up short quite often. After calling these dealers to complain they told me that they weigh the projectiles instead of counting them. The problem herein is that projectile weight varies and most of them I weighed were heavier than the stated grain weight. This ultimately leads to not receiving what you paid for. I might be wrong but I feel these dealers should disclose the possibility that you will likely be shorted due to their weighing projectiles versus counting them. If this helps anyone then my rant will be worth it. Being new to reloading I had to learn the hard way. BUYER BEWARE!
