My 40 cal semi auto pistol shoots factory loads (even the cheap stuff) with no problems but I have been having trouble getting the same reliability with my reloads. One FTF every magazine or two.

After cleaning my pistol and before re-assemblying with the barrel in one hand and cartridges in the other I compared the way factory and my reloads would feel riding up the feed ramp and into the chamber. There was a definate difference with my reloads having some resistance when they would break over and feed into the chamber.

I measured and looked but what I wound up doing is adjusting the crimp die down until the finished cartridge felt the same going into the chamber as the factory cartridges. 100 Rounds today and no FTF.

Just thought I would share.
Have a great day!
