I am not sure what you mean by a rammer, I know what they are but can you post a picture of one made for a bofors? I would think a small dowel of wood with a cloth or leather covered end would suffice.
Also if you notice in the video he has removed part of the barrel lock to make it safer to hand load, the part that comes back onto the breach block has been removed. Mine has this bit but I will likely do the same and cut it off.
It looks like he has set it up on some sort of pull cable squeezable trigger. I can only see that working if you modify the cam and weld a bit on the bottom of the block to give you a new trigger..... I will puzzle this out.
Thanks for all the help so far.

The Rammer is a large heavy spring loaded tray which fits in the bofors casing.. The round falls through the gates and lays on the rammer, Its then thrown forward when the gun is fired and rams the round into the chamber..

How much of the bofors do you have?

The rammer pins onto your breech, if you look at your top photos, top right photo on the right there are two holes which take the rammer securing pin.

The rammer pins on here and is a large gun metal tray with a spring inside and claws which throw the round into the breech.

How much of the cannon do you have? Do you have the housing which takes all these parts? You top photos show the breech casing, do you have the bit that it slides into.. including the cocking lever and selector lever?

I Am guessing you have an entire bofors cannon minus a mount?

I can photo a rammer tomorrow if you want to see one.

What you see is what I have and all I need. The barrel end is only 15inches which is barely longer than the breach. This is going into the turret of a (reproduction) 1936 Vickers light tank in place of the 2pdr that should have been in it. All I wanted was a working breach, I will modify what I have to suit the turret mounting. The rammer tray you speak of was broken off of mine and the part that was attached has already been removed at the take down pin prior to the pics.
I just needed a working breach so that's all I bought.

Now I understand... Apologies I was in Bofors mode!!
As you say you will need to modify it to fit and function...
I am glad that you got it stripped down...
Send me a photo when you finish the conversion..!!
The breech will fire off when closed, I am sure it can be modifed to not fire.
You could also message that chap on the film you shared here and ask him how he holds back the pin..
Glad I helped you up to now..
