Is the powder drum/clean out screw / nipple removable on CVA cap lock rifles? If it is are they standard threads or left handed. Need to remove one and thought I would ask before messing something up.

The threads are standard right hand. Might I ask why you NEED to remove the drum?

It's not really made to be removed so if you remove it, it may get buggerd up.

I think I got all my questions answered from a post in 2014. The photo in post number 16 is good info. Looks like I may not need to remove at all.

You can NOT remove the drum on a CVA! They are installed and THEN bored for the powder channel. Unless you have the right tools you will not get another drum to fit just by turning it in. They are a PITA to work on. That is why the drum has NO wrench flats.
Removed my one out of a CVA Mountain rifle recently. Just put it in a vice and unscrewed with a pipe wrench (RH). The thread for the nipple was buggered. It was the drum with the screw that goes across the barrel inside and just screws into the off side of the rifling. Replace with the newer type from TOW and no issues, some filing of the drum to get it to line up with the hammer but pretty simple really.
TOW Drum-CVA $6.99 . 12.5mm, 10-1.25mm, threaded 6-1mm nipple. Just checked they have them in stock. Its a short thread and screws into one side of the barrel like most do not righ across like the old originals. Mine has worked fine with loads up to 140gr powder charge (58 cal)
Thank You very much. Hope I don't need it though.
I removed mine years back and converted it into a flint lock.

They come out easy!! I have done several - use a diesel spanner - its like a ring spanner with a slot in the end so they can slip over the injector pipe - leave the nipple in the drum and just fit the spanner over to turn it out - they come out clean and easy - if you gonna replace it make a small index mark on drum and barrel so the powder channel lines up right ---this is a simple easy deal with the appropriate tool !!! ...................................they are a metric thread
We put a pipe wrench to it. It broke flush with the barrel. After several drill then EZ-out the metal got thin enough to tap. Ran a correct size metric tap in and cleaned right up good as new.
I was thinking that you could use a socket that slides over the drum. Just drill a hole in it's side for a screw that will run into the nipple hole. Though I might need to pull the breach plug on a CVA mountain rifle I picked up which had a load still in it and was planning to drill a socket for a removal tool. Got the ball out with a puller instead.
