Has anyone ever tried to add a spacer to a spring in order to add more pre-load?
studying this Kimber of mine, I can add about .35" of spacer without experiencing coil-bind......
just wondering if this is a viable option of increasing spring strength?
Sounds good in theory but I don't know. I know there are higher poundage aftermarket springs for Remington 700 from places like Brownells. Maybe they can help. http://www.brownells.com/
I changed the spring and pin on my 673 to get a quicker lock-up. I don't know that it really changed anything, but neither do I believe it hurt anything. JD is correct in suggesting a talk with the people at Brownells.
Remington's rifles, having electronic ignition, were a total bust. Even the experts can fail when it comes to messing around with something that is not broken.
Probably the "Speed Lock" springs already mentioned are as far as I would go, in terms of getting more rapid lock time. Even then, the only time that I have ordered an used those springs, was when I had old military rifles with broken or very worn springs.

There are other options, including fully assembled, ready to install speed lock pins and springs in a bolt tailpiece that will screw right into your existing bolt for about $90. Just search Brownells for "Remington 700 titanium firing pin" and you'll get a lot of choices. You could also look at Sinclair International, MidwayUSA, and others, as many retailers carry pins and springs and assemblies.
If you do this mod, please post your results, as I'd like to know how it impacts accuracy in your rifle. I've got a 700 with the firing pin lock that I'd like to convert to a smooth shroud, but I don't want to screw up function or accuracy.
