Has anyone had any ftf in a 500. Currenty am having trouble with

Hornady Brass
CCI LR primer
H-110
400gr Sierras

I currently suspect the brass. Have some starline on order to test theory.

Seriously doubt it's the brass. I'd check and see if the if there is any crud in the firing pin hole, that may be keeping the firing pin from hitting the primer hard enough.

If it appears that the firing pin indention in the primer is adequate, then the most likely cause will be the primers them selves. If any oil or type of solvent came into contact with the priming compound, they can easily be ruined.

The load that FTF used Hornady brass and CCI LR primers Just tested Starline brass with Fed 210M primers. No problems So it's either CCI primers or Hornady brass. Primers were clean and fresh and work well in other firearms.

The gun is fairly new as far as use goes and have had no trouble with corbon loads.

Have you fiddled with the springs at all? May not be hitting the primer hard enough, if you put in a lighter spring, or didn't tighten it down all the way after cleaning or working on it.

Remove the grips and check the strain screw, it may have backed out. It's not uncommon for this to happen and when it does you'll experience light hammer strikes. CCI's DO have the hardest primer cups.

Well, the only way for the brass to be at fault here is either the primer pockets are way to deep, or the flash hole is obstructed or non-existent. In which case you should take a primed piece of Hornady and one of Starline, and check the depth of the primer face to the case head. There would have to be quite a big difference there to amount to not firing. If this is once fired or more, then I would lean toward the flash hole being obstructed by some cleaning media or the like.

Again, I seriously doubt that the brass in itself is the culprit, just not really any physical way unless primer pockets are deep, missing flash hole, or maybe the rim thickness is way to thin. All of these fall into the catagory of "HIGHLY UNLIKELY". Most probable would be either brass prep (flash hole obstruction), primer cup to thick for the main spring of the gun (this one is unlikely unless someone has made adjustments or modifications to the gun as it was designed for large rifle primers and not large pistol primers) or the primers were contaminated.
