[QUOTE="Fiftydriver, post: 180284, member: 10"] To clearify my post a bit. I have found that the fit of the firing pin to the firing pin hole does not have much effect on the level of cratering. I have tested a small diameter pin in a large diameter hole and a tightly fit large diameter pin to a larger diameter hole. In both cases, there was excessive cratering. That said, I have tested with small diameter firing pin holes and just for testing sake, I turned down the small firing pin even smaller to 50 thou in diameter. There was hardly any cratering with either pin diameter with the small diameter firing pin hole. I asked for the firing pin to be measured because that is much easier to do then measuring the hole diameter for most shooters. If a pin of 75 thou will fit in the hole, we know the firing pin hole diameter is pretty large. Hope that clears things up some on my thoughts on the subject. Kirby Allen(50) [/QUOTE]
