[QUOTE="Mikecr, post: 799782, member: 1521"] The firing pin is held back and released by the trigger. Therefore, the trigger directly affects firing pin impact. It affects the amount of pin fall on release, as well as friction in this fall(as is solved by the Kelby replacement for Jewells with certain actions), and yes lock time for sure. Bolt TURN/POSITION is also affected, and you should mind the consistent stopping of bolt turn. Don't assume it. If, with a given trigger(not model but actual), you have not set the pin strike for best grouping, you probably have not reached the best from your gun. I have whitnessed a perfectly firing mis-setting of a firing pin cause ugly performance. Flyers.. This is an area rarely looked at or discussed. I believe there is a lot to learn here. Ever wonder why we're left to swap primers trial & error during load development? Why a primer that sucked for you works great for someone else in the same cartridge & load? The answer is primer striking. Well actually, the ABSTRACT is primer striking.. [/QUOTE]
