I purchased some .380 projectiles from a guy that had "Midway USA .380 95gr" hand written on a baggie. Not new to reloading, have reloaded 9 and 40 for about 6 years, but new to .380. Processed cases like I have always done but when I tried to seat the bullet on most of them there was little to no neck retention allowing me to push the bullet in farther. I seat and crimp in different steps so I tried a little heavier crimp and it helped with a few, maybe 20%. Adjusted the expanding and crimping dies a couple times but no change. So I did probably what I should have done to begin with and checked the projectiles. I measured 20 and they all weighed between 95.2 and 96.1 but got a surprise when I measured the diameter and all measured .350 and not the .355 that I have read everywhere else. What I learned, don't assume anything in reloading, do the smart thing and verify. I honestly do not think the guy tried to pull a quick one on me and I can not find any projectiles that are .350. Please learn from my mistake.
