[QUOTE="archangel485, post: 2127992, member: 97905"] Not stupid at all, I didn't know it was a thing to even look at until just a little while ago, and I've been shooting a long time, haha. Anyways, I used the "stem" end of my calipers (not sure what it's actually called) and measured how far the firing pin indicator was sticking out the back side of the bolt while the bolt handle was lifted. Then I closed the bolt and measured it again. In my case, the indicator was like 10 or 20 thousandths further back when bolt was closed then when the bolt was opened, so it was actually hitting the firing pin harder than necessary. Anyways, I removed that much material from the front side of the cocking piece until the measurement was the same for bolt open and closed. I was just thinking it's possible (though seems fairly unlikely) that your action is actually allowing the firing pin to move forward when the bolt is closed when compared to the bolt open, and if that was the case that would mean the firing pin spring isn't compressed all the way while in the "cocked" position and might not hit the primer hard enough. I hope my description is good enough to make sense, my apologies for my lack of understanding on all the terms. I can send you pictures later if it's not clear. I bet you can find more info on the forum somewhere too if needed. [/QUOTE]
