You could say it's twice the work putting it back together but I can't say it was a problem or anything, used the same cut off case head and clamp I always do.

sketch Posted November 22, 2022 Report Share Posted November 22, 2022 It's the same as the single ej. Bolt, depress the ej's with a spent case (or cut down case) drive the slave pin out and remove one before the other. You got that bolt pretty quickly 🍻🍻 Quote Link to comment Share on other sites More sharing options...
shooterrex Posted November 22, 2022 Report Share Posted November 22, 2022 Vice, 2 45acp cases and a pin punch All you need. Maybe an extra pair of hands. 1 case over tail of the bolt. 1case in the head. Tighten in vice Remove pin(s) Loosen vice. Quote Link to comment Share on other sites More sharing options...
98Z5V Posted November 22, 2022 Report Share Posted November 22, 2022 ^^^ This process is the best way to go. Mike, both those ejectors are held in by the same roll pin. Quote Link to comment Share on other sites More sharing options...

Magwa Posted November 24, 2022 Author Report Share Posted November 24, 2022 Ok so maybe there is a new model as mine has two pins one for each ejector I am going to use the 45 acp method but have to buy a drift pin that will fit going to town today....

DustBuster Posted November 25, 2022 Report Share Posted November 25, 2022 The bolt I took apart from Sharps had one pin keeping both ejectors in place.... The other pin that you see may be for the extractor... but Regardless, One TIP: when I worked on both a single ejector and my dual ejector bolts, if you clamp or vise a cut off casing to depress the ejectors, you may want to if you can back off on the pressure of the vise so that if not fully depressed. When I first did it, with the case completely squished in there so it was straight just like a regular bullet would be, it caused too much shear friction on the pin so it would not pound out. Backing off on the ejector squish a tad lets the pin be loose in the ejector slot and won’t require nearly as much force. Good luck Quote Link to comment Share on other sites More sharing options...

I just quoted this so you might be notified of my Tip I just wrote.... maybe you have already completed the task by now... it’s tricky to stabilize the bolt if it isn’t clamped fully in a vise, but what I did is I drilled a hole to accept the skinny tube part of the bolt, into a 3/4 inch piece of wood. Then with that against one jaw of the vise, and the cut casing on the other jaw of the vise, I cranked it nearly tight... then I slipped another block of wood under the bolt but on top of the bottom shaft of the vice. I think then I sort of had to use something else then on top to keep it from wiggling out. I wish I could remember more, but you’ll figure it out Quote Link to comment Share on other sites More sharing options...

Magwa Posted November 27, 2022 Author Report Share Posted November 27, 2022 Ok got everything taken apart and used the go gauge and the bolt goes in and locks, so I tried to make a no go gauge from the go gauge with the tape method but the only tape I had was really thin and it closed on it as well after a little pressure so am I ok to go?

DustBuster Posted November 27, 2022 Report Share Posted November 27, 2022 (edited) I can’t remember how many slices scotch tape it took to add .004 to equal a no-go gauge... I’m thinking 2 slices was close. I only did it out of curiosity when I rented some gauges and wanted to see how many slices made up the difference. I now use a No-Go I bought and use that to accurately size a go sized brass casing. I’m not sure of the Creedmore size difference between the two gauges. Someone else will have more tape information. @Magwa, how did you remove the ejector pin(s) on your bolt? Was it easy for you? Calipers and a homemade comparator would be useful for this or future checks of various sorts Edited November 27, 2022 by DustBuster Quote Link to comment Share on other sites More sharing options...
Cunuckgaucho Posted November 27, 2022 Report Share Posted November 27, 2022 Scotch tape probably compresses being soft, either take a sacrificial feeler guage set and cut up a 4thou onto a disk. Just a tiny dap of grease will hold the piece on the back of the go gauge. If you know someone at a machineshop you could see if they can give you a small piece of 4thou shim stock and use that instead of cutting up a feeler gauge.

Calipers and a homemade comparator would be useful for this or future checks of various sorts this bolt did have two separate pins one per ejector I had to make a punch for them they are tiny once I had a punch it was easy I drilled a small piece of hardwood to except the gas end of the bolt then i cut a base off a creedmoor brass and used that in a vice not super tight but just a little off tight and they came right out yes it is a PITA but done now I ordered a no go gauge last night so I will have it soon and be done with this and get to load development...

DustBuster Posted November 28, 2022 Report Share Posted November 28, 2022 Right on. Good conclusion to the process... When the no go doesn’t close, you will feel more confident on a kick butt chamber. I did with mine... Quote Link to comment Share on other sites More sharing options...

Magwa Posted December 2, 2022 Author Report Share Posted December 2, 2022 Go gauge was a GO and No Go was No Go so I am set operation 6.5 Creedmoor is up and ready to rumble, I am adding a Luth stock to it It has a 22 inch Aero Barrel and I installed my Vortex PST 5 to 25 on my Larue 111 quick detach mount and a dedicated toolcraft BCG dual ejectors.... I will start load development this week so if anyone needs go no go gauges I have them for loan....... pictures to follow..Thanks to everyone who helped me get this done I leaned a lot..
