I have replaced the recoil spring (made by Wolff gun springs) and the recoil buffer (from gunparts Corp.)

I’ve been shooting some factory ammo I purchased in the 70’s and have been reloading cast bullets in cases I make from 223 rem brass.

I would love to know if anyone is doing the same and what components for reloading your using. 

Only advice that would be most important is to change the recoil spring and install a new buffer. Old worn out springs and buffer will damage the gun over not so passage of time.
