Primer pocket not causing any problem. The six rounds that allowed me to close the breech fired off nicely. It is so very nearly there!
Just tried chucking a round in a hand drill and holding a sharpened chisel against the rim in an attempt to just take those few thou. off.
It did not go well...

I actually brought the drill into my study from the man cave, to try this little engineering experiment.
Not often my wife swears.

Have you thought about reducing the thickness of the rim from the other side? Instead of thinning down from the head side perhaps you could use a watchmakers file to take a small amount of material off the front face of the rim while its spinning?

It was always the intention to trim the rim from the non-head end the rim of the cartridge. See how important correct nomenclature is when describing stuff!
Now on the look out for a cheap and cheerful lathe...

Sounds like you're going to need to pull the bullets then! I've been looking for a small lathe for a while but prices seem to exceed what seems reasonable to me for the very small amount of use it'll get to trim down some Hornet cases. Also going to need the correct size collet plus a properly sized mandrel to stop the case getting deformed in the chuck & ideally a live centre for the tail stock too...

So Mrs S62 is off to the seaside with the children which leaves me unsupervised and looking for trouble.
I know. I will strip down the .310 cadet, clean it thoroughly and put it all together again.
Well I managed two-thirds of today's mission. I simply cannot get the action back into the rifle. I have endured several shocking YouTube videos in an attempt to find a solution but to no avail.
Also (because there was no responsible adult in the house) I loaded all 200 rounds which I had manufactured from 32-20 brass. I could only close the lever on 76 of them. For the life I me I cannot work out the difference between those 76 "good" rounds and the remaining 124 "bad".
However, since I have now "broken" the rifle, it is all rather academic really.
Ever wished you had just gone to the beach?

I presume you have replaced the firing pin and spring into the Martini action, if so depress the action lever (if you can) locking the action and leaving the lever in the down position, ensure all the cross pins through the action parts are flush with the action body and insert gently back into the action housing keeping it vertical then replace the action retaining pin.
If you find its too difficult parcel it up and send it here to me and I’ll give it a home.

Yes the action closed perfectly before I started dicking about with it.
All rounds were made at the same time and and in the same way. I just cannot fathom it. I did manage to fire off six rounds at Bisley this week and there are another 70 or so that will fire off.
I will pass the issue to my son who is an engineer and see if he has a solution for returning the action into the body of the rifle. He is a man with a gift for fixing things and consequently, I suspect was the product of an illicit affair my wife had many years ago.
If he cannot fix it, then I will admit defeat and take it into Fulton at Bisley and undertake the walk of shame to their dark, dingy counter staffed by their oft surly staff.
I really need to stop "experimenting" with my firearms...
Because the rounds were made at the same time and in the same way won't insure that they are the same. To my question: before you decided to clean the rifle and it was working properly. Did the action close on all the 200 cases at that time? I usually chastize my Brit brethren for over use of a vernier caliper but now would be a good time to measure the hell out of the cases that worked and see how they differ from those that didn't. I have been there. I have done all of that.~Muir

The issue is, I very much suspect, that I was trying to make .310 from 32-20 brass.
I do have (ironically) 100 rounds of Bertrum .310 but was trying to save money (more irony). When I made the brass and took it for a try out, none of the rounds would chamber.
I know I should have checked that back at the Ranch; but what are you going to do?
Thanks to some advice (FH) on SD, and a last minute brainwave I put all of the live rounds through the resizer again (minus de-primer obviously).
I then checked that they all chambered - and they did. What I did not check, was if I could close the breech on them.
Hence, this week's "six shot" trip to Bisley.
Back at the Ranch: I chamber and try to close the breech on all the rest. The results were 75 OK, the rest would not close.
Unattended male left at the Ranch; thinks to attack the problem from the other end, and dismantle and clean the rifle - perhaps there was some muck in the mechanism.
Dismantled, cleaned ...you know the rest. The breech will almost go back in and I have even given it some gentle encouragement with my precision mallet before my wife called a halt to proceedings, telling me I was about to destroy of lovely bit of history. She was right.
I need to get the rifle back up and running again and I suspect I am going to have to pay a professional to do so.
I also need to bite the bullet (intended) and buy some more proper .310 brass.
The rifle now sits it a cleaning rest, alongside her metal work and the all important pins, which I will try not to loose, before I hand her over to someone who is not a carpet-bagging-wannabe-gunsmith-idiot.
Not sure whether to spend a day of my life (of which I have fewer and fewer) measuring the Frankenstein rounds, or just chuck them in a firepit and seek professional counselling in case I am ever tempted to go down a similar road again.

Measure. I'm guessing rim thickness. An alternative -and one I have had to use- is a one time payment to a gunsmith to deepen the rim cut in the extractor and chamber so that you can use un-fussed with 32-20 brass.
I had a thought: When you get the rifle reassembled. Chamber a round without the extractor in place. See if the breech closes.~Muir

I shall ignore that unkind and frankly, unhelpful remark on the basis that the results may cause me to sink further into a depression of my own making.
Much as I did your Post #5 from the 30th September 2020, which advised me to buy .310 brass and save myself the effort.
