I have a Ruger Mark II, stainless TARGET model with the 6 7/8" tapered barrel. I am the 2nd owner, and it is in very nice condition, but unsure of the round count...
In tuning it up for the Postal Pistol League, while zeroing the RDS on a bench rest, I noticed little crescent moon shaped pieces of lead on the bench ... sure enough, the Mark II was clipping the bullet somewhere on either the feed ramp or chamber throat.
I tried all 6 magazines I have (2 stock, 4 aftermarket) with same result. Tried 4 different brands of ammo I have here, all 40 grain LRN, some with a copper wash. Same end result...
Initial research indicates that: A. it's not uncommon and B. there is only peril to try and polish the feed ramp or chamber throat, as it has zero extra metal.
ONLY Thing I have seen that may solve this is a very small radius cut on the chamber throat, like .002" IF that is what is catching the bullet.
Anybody have any experience with this? How about a local gunsmith reference also? I'm out in Hillsboro, would like to find somebody on the west side of PDX ... I have done the Volquartzen Accurizer kit install, which is fantastic, so would like to use this gun, but this problem is beyond my capbilities I'm afraid.
Thanks!
