I recently started having issues with the lock not striking the caps hard enough to fire. These are the new CCI caps but I'm not having issues with them in my Traditions or my TC Hawken. Wondering if I can buy a stronger main spring?

re temper or maybe deer creek products will have a new one, and get a spring compressor if you dont have one.
Back the rear lock screw out. Sometimes they are too long and when you snug it down, it protrudes and hits the hammer, greatly slowing it down.
Weak springs are notoriously soft for the CVA and Traditions Rifles. Part of the problem could be the nipple which may have mushroomed a bit. A simple fix could be the replacement of the nipple or just a brief touch up with a file. A small wood wedge can be slipped in at the vee of the mainspring to add a bit more tension to the spring.
Traditions main springs are far from weak. Cva you can remove with a simple pair of pliers.
The Traditions springs for their Mountain Rifle will likely fit in a CVA Mountain Rifle.

^^^ Try that first. Also check the cup of the hammer that there are no spent caps stuck in there.
Traditions springs are larger and use a different pin that goes through the lock. Not the same guns.
thirty plus years of CVA shooting/gunsmithing if the gun has just developed this
1. pull the lock and check if there's a rub line on the inside of the hammer fix: grind/file off 1-2 threads on the lock bolt
2. pull the nipple and install a new one. a nipple should/is a consumable item when it doesn't go off on the first strike examine to see if the cap looks bulged if so it needs replacing (by this time chances are it has burned out the orifice)
3. If you find spent caps in hammer open the notch in the front of the hammer and shorten the rim of it along the rim so that you can clear spent
ones with a flick of your finger.
If you have one of the original locks the have the bridle to support the tumbler you have the best lock made for your gun bar none

First two things I thought of have been mentioned: dead cap build up in the cup and mushroomed nipple. My rifles were made before they started to cut a V-notch in the cup and stuck, fired caps is the most common cause for me. I dig them out with a patch knife. Light filing removes the mushroom bulge. Hope it is as simple as that for you.
Thanks all for the thoughts. Since it's -25 here this week it's a perfect time for a little fixing in my heated shed!
I checked the hammer, no spent caps. Cleaned the lock and filed off 2 threads on the rear lock screw. Seems to work good now. will take it out to the range after Christmas!
If it shoots well I'd replace the lock with a L&R RPL - I did this to mine and never looked back - ignition now 100%
