I appreciate your expertise and have read many of your posts especially on recoil spring rates.
My question is this:
I ordered a Wolff 18.5 conventional recoil spring for my brand new Colt NRM 1991. I have yet to shoot it but was a little afraid that shooing Corbon +P 165 gr. ammo at 1250 ft. per sec. would damage the frame. Not that I would shoot a ton of that be enough to get used to it because that's what my defense rounds is. Your formula comes out to be about a 19.5 lb. spring. Then I got worried that 18.5 would be to heavy for the rest of the ammo I shoot which is Winchester white box or other plinking rounds. So, I clipped a full coil off and smoothed the edge up.
Did I mess it up? Now the spring is about a coil or a little more shorter than the stock spring. Is that a problem?
Logic would dictate that each coil is worth the number of coils divided by the spring weight? 32 coils / 18 lbs. = .56 or about a half lb. So I cut off 1 pound and now have a 17.5 lb. spring?
Thanks for your time and knowledge.
