I have the above rifle. I have been twiking it and learning about gunsmithing! Just a side note, my grandfather was a practising gunsmith in Kansas City back in the 20 an 30's! So I may be following in his footsteps.
I have sent it back to be worked on by Charter Arms and an at that point where I have just (Currently) one problem. They resolved one of my problems and attempted to correct this one, but did not. I prefer at this point in time, to work on it myself or have my (Real) gunsmith work with me.
Misfires! Sometimes it misfires 4-6 in row, sometimes it fires 4-6 in a row with no problems. The misfires occur with both types of brass, 348Win and Jamison 45-75.
I use mainly 348 reformed brass. headspace for these run about .003
I also use some Jamison 45-75 brass and the headspace is about .005 +
I would like to add about .002 to the tip of my firing pin, to see if that would help. I have a great gunsmith here in Houston, Texas that can do the job. I do not want to puncture the primer, merely extend the firing pin and properly harden it. To see if this would get rid of the misfires.
Has anyone done this?
Has anyone else looked at the hardness factor of the firing pins? I know that on my Uberti's, both rifles and pistols, the firing pins were always way too soft. Over time of shooting, there is a mushrrom effect that occurs on the front of the firing pin that strikes the primer and in due course shortens the firing pin to the point of misfires. My gunsmith would properly harden the firing pins on the pistols and I would purchace new machined steel firing pins for the rifles.
I also wonder if it is possilbe that my chamber is not cut correctly for the brass I am using.
Your thoughts and experiences are appreciated for this Journey of mine!
Sincerely
