yes, infact being so cheap I think I'll give it a try on the 4lbs firing pin spring...
I still do not wish (maybe) to change the pin safety spring as it is a safety feature and I would not want to have troubles with it...
But concerning the 4lbs firing pin spring, can there be any trouble (misfire) when used with CCI 350 Large Magnum primers? I mean, are they harder than the CCI 300 or the force required to ignite them is the same?
