The Saga of W7612XX Cartridge Lip Missing on Bolt Base Charter Arms sent me a base bolt that had the cartridge support lip. ALL originals were made with the lip and if you don't have the lip on yours ... call Charter Arms. Found out that many rifles are/were missing the lip because some idiot at Italy ground them off!
Firing Pin Hole Not Cut Correctly During the first 50 rounds through the rifle, noticed that the primer hits were near/on the primer hole. Toke the bolt out and the piston (original name for the firing pin) ... looked and yep - egg shaped. Was corrected with the new bolt base from Charter
Carrier Block Droops Below Receiver Excess Head Space These 2 problems - I packed the rifle in the truck and drove to Charter Arms because they were waffling about the fix. Nick Ecker and I disassembled the rifle after I proved to Nick that I had 0.014 excess head space and the Carrier Block drooped 0.019 below the receiver. We rummaged through the box of links looking for the longest ones - found 2 that were longer. With the bolt in battery, still have excess head space but with a 348 resized case in the chamber - head space is ZERO because the shoulder eliminated it. I consider this a fix. Also, a new Carrier Block and Carrier Lever were installed
Made a verbal agreement with Nick Ecker while at the plant ... if the head space worsens, the rifle will be replaced or a new barrel put on it
Why is there excess head space to begin with? Because Italy indexed the barrel incorrectly before it was installed onto the receiver.
Magazine Ring Doesn't Fit Flush into Dovetail Cut Magazine Plug Lip Doesn't Fit Flush into Barrel Cut ... which causes the magazine tube to extend past the muzzle of the barrel and is an open issue, presently. IF, Italy made the magazine plug lip bigger and custom fitted it into the barrel cut slot - 1/2 of the problem would be fixed before it left Italy.
... if the elliptical dove tail was properly cut so the magazine ring fit FLUSH in the cut (I have a 0.014 gap) - the other 1/2 of the problem would have been resolved to preclude an 'extended magazine tube' and only be able to shoot the rifle as a single feed.
Italy came up with a threaded screw and sent me several (for the 4 rifles we have). Thread is metric, so I threaded a 6/32 screw into the tube ring. Still didn't hold the tube in place. Next, I took a 6/32 tap and broke the end off while doing the tap. The 'teeth' on the tap should have held the tube in place ... NOPE!
So, a new magazine plug is being made on my friend's lathe with a larger lip. The tube ring is at the welder having a TIG bead applied on the top of each end of the ring. The ring will be milled so it will be flat against the barrel in the slot cut to eliminate the 0.014 gap. Then the magazine plug will be custom fitted into the slot cut - after the tube and tube ring are properly set in place.
OK ... why am I going through this mastications instead of getting a replacement rifle? Here's why ...

... 50yds

... 100yds

... 200yd target (no X's on patches) and the patches with the X's are 300yd bullet holes shot on a 200yd target, including the one Bulls Eye! PS: the wind was gusting to 25mph from 11:00
In addition, I shot 500 meter Rams with consistency
