So I bought 2000 45 FMJ from Precision Delta. My first purchase with them. They arrived and I started making a few measurements. Started finding large variances. So I pulled out 100 random bullets out of the case and measured length, diameter and weight. Here is what I found:
Is this normal for Precision Delta? I'm worried about the drastic variance in both weight and length. My pressures will certainly go up with the shorter bullets as my case volume decreses. Am I making to much of this? Seems inconsistent production to me.
