Do a full clean and lube job on the gun. Get all the residue out of the hammer and trigger section using an old toothbrush... Then coat the parts with dry lube (for guns). It will seep into the cracks lubricating everything, and then dry off so it doesn't attract dust. This may help reduce the resistance of the slide coming back and cocking the hammer. The recoil spring is pretty much tailored perfectly to stop the slide and the perfect moment, so the recoil is almost nothing when you do all this.

The temperatures were between 40-50 all three days. The gun didn't have 100 rounds through it since being cleaned on day one. Day two load test were with a clean gun and day three was pretty much a continuation of day two with no rounds fired between the sessions.
Regarding the Federal Champion 115 grain what year was it manufactured? Where was it purchased? How long did you have the ammo, if it was for a period of time how was it stored? Temp controlled in a sealed ammo box with desiccant? Have you checked with the manufacturer for lot problems? I am interest to know as other people has had issues with 115 GR Federal Champion? Thanks for your time. PM if you want.
I don't do anything special for storing ammo, other than to keep it out of reach of my daughter. I'll check on manufacturing date when I get back home. I've taken the advice of some here to leave my FNX with the slide locked back to see if that will help ... hope to hit the range sometime this weekend.
Ive only shot federal champion and only had one failure to eject, and I was holding the gun stupid. Have over 500 rounds through it I believe. Its the cheapest thing wally world has. Have never expected to much from it.
I also would assume its the ammo, not the gun. I shoot Winchester white box every time i go to the range. I have over 1700 rds through my FNX9 with only one FTF during break in and one stovepipe due to a defective round.
Try switching ammo.
