I picked up a Colt Series 70 (made in 73 or 74 I think, by serial number)...beautiful blue, solid, and it works. But, here's the problem... Occasionally, it won't eject. It extracts just fine, but the casing itself is tilted half-way out the port, but won't come free...oddly, it only happens with certain magazines (tested, and yep, they were habitual problem children). Didn't matter if I was shooting plain old ball or +P JHP's... Only change I made to that particular part was replace the main spring with a new standard Wolff one, NOT an extra power one (I don't think it's an 18# but it could be...the label on the package makes no mention of extra power or poundage of the spring) The next round is fed, and has bounced into the chamber when I notice the stopage. So, I'm thinking...either my ejector isn't long enough, or my extractor is holding on for dear life too long? If I drop the mag and clear the chamber, and push the empty case back into place, I can hand-eject it with no problems. Same if I manually cycle ammo; it all hand-ejects without a problem. The extractor DOES clock a little, but at all very much...and like I said, I can pretty much repeat it with certain mags (one of those mags being my only Wilson 47D, most of my Mecgar's, and some admittidly out-of-spec USGI's; those cheap ones out there for sale now..and these are visibly way out of spec either follower or feed-lip wise) Looking at past posts, it looks like the ejector is a real PITA to remove and re-fit a new one  Really, how difficult is it to fit a new ejector? What tools would be needed, assuming all I had was a workbench and a punch? What else would I need? Including micrometers, etc...all I got is my eyeball, a punch, and a dremel...and I don't like using the dremel on this stuff

All you need is a hammer, work bench and a 1/16 inch punch. Drive the ejector pin out and pull the old ejector out with some pliers or whatever. Put the new ejector in and with the 1/16 inch punch in the retaining pin hole 'mark' the front leg of the jector with a light hammer tap on the punch. Remove the ejector and using a small round file cut a small 'slot'. Then reinstall the ejctor and install the ejector retaining pin. I strongly suggest that you use the Wilson extended length ejector available from Brownell's. Do not file anything on the ejector until you test fire the gun and see where the brass is landing. BTW, did you replace the main spring in the mainspring housing or the recoil spring in the barrel slide? Take care. Charles the Gunsmith.

Sorry, recoil spring, not the one in the MSH.... Hm, so I'll need a small round file...ok, that I can work with. Probably could use one of those "action blocks" they also sell at Brownell's; right now I basically use a folded towel as my block.. I don't much care where the brass lands as long as it a) does not land on me and b) ejects, %100 of the time...I don't reload just yet, so dented brass is a non-issue to me  When I get some spare time (and more importantly money) I'll dig this sucker out and do some surgery...
