Ok, look a the pictures first.
A recently fired case: (5.5 grains of Bullseye, 250 grain 429421)
Here's the deal. I noticed this after cleaning the other day and the firing pin was "stuck out" not allowing the cylinder (loaded) to close easily or rotate after it was closed. I've since "freed up" the firing pin and the gun still shoots like it did 25 years ago. What I can't figure out is what really caused the "dimple" around the firing pin hole.
I had a theory that this was caused by the primers working in and out during firing, but I've had no loose primer pockets ever. The gun has seen a pretty steady diet (say 30-40%) of magnum loads and the rest have been the load listed above. While the magnum loads have been "hot" they were not excessive. 24 grains of H110 or WW 296 and a 240 grain XTP or Remington hollow point.
I have absolutely no idea how many rounds this gun has shot, but if I were to guess? 5-6000?
