I started reloading 40 S&W a few days ago. I loaded 180gr FMJ FP bullets using WST (4.7 gr) data from the hodgon reloading site.
Took100 rounds to the range The first two magazines fired excellent and without issue. The second set of magazines I encountered two jams with the breech not returning all of the way. I checked the barrel and noticed an unfired cartridge in the barrel. I tried to remove it, but it was jammed. I borrowed a stuck case remover and removed the bullet. it happened one more time with my reloads. After 100 rounds, I switched to Magtech 40 S&W ammunition and fired 50 shots without issue.
I compared the cases and noticed a bulge on the bottom of the reloads. I have never seen a bulge that low on any other bullets that I reload (9mm, 44 special, 45acp).
Has anyone experienced this? Is it caused during the reloading process or does it occur after being fired. Below is a pic with crude arrows to compare against an unfired manufacturer bullet on the right. At the point of the arrows is a bulge, which is what caused the cartridge to jam and not fully seat in the barrel.
Any help or recommendations would be greatly apprecited.
TIA
