[QUOTE="Kennibear, post: 885313, member: 51650"] JHansen Put a speed lock on a M98 Mauser in 30/06 (with a +9lb 27' barrel 1.25" diameter full length) back in the early 80's. The firing pin was not changed but a much stronger spring and modified tail piece to shorten the throw were included. I believe it did as advertised. Savage, Remington (w/ the 788) and other manufacturers brag about short lock times and the Olympic crowd seeks that out. I would be leery of a light weight pin unless it were backed by a substantial increase in spring compression. It takes a thresh hold of strike energy to initiate a primer. I wouldn't own a firearm that wasn't 100% bang. The pistol speed lock makers warn against using race gun triggers for duty/ carry/ personal use. The firing pin being too small for the bolt face pin hole is a huge concern. That means the pin has clearance on the side to be jammed and/or damaged by primer cup material. It's possible that the pin does a little shimmy as it pops forward and that has to increase wear and cannot help the speed. I was taught by all the old school gunsmiths that that condition was a must fix/ safety issue. Maybe the speed lock you bought wasn't as quality as it should be. But my vote is "speed lock on every gun". [/QUOTE]
