Any pictures yet or is it still being designed.

I guess an old rifled barrel would be the answer, but I think that's kind of cheating

That sounds tight. I used some stainless pipe from Mcmaster https://www.mcmaster.com/tubing/metal-tubing-for-flow/smooth-bore-seamless-stainless-steel-tubing/id~0-183/ at 150psi I still had to slightly open the loading end of the tube to pre-compress the skirt a bit. Dome head pellets seem to be mos...

I tried to keep it simples (KISS)

Purge weld (Tig) is the only way I know of, can you purge with stick ? probably too much heat, that's why you get the burn through.

Aluminium block I found, it was quire a lot of work on the drill press. Getting the right spring and piston was the tricky part.

And another transformation into Nerf Rival, mainly for the grandchildren to play with
BFG cut down and reshaped. Gravity fed tube holds 8 rounds.

So it's firing one BB every shot ? I made a semi-auto airsoft with a bolt which blocks the ammo feed tube which works great, now that it's sorted

So its final iteration, it has transformed into a Nerf Rival single shot muzzle loading. Fake magazine is just for holding spare balls.

Got a new toolbox for Xmas

It's 2020, would you expect anything different, wait until next year at least.

No idea if it will work, but tinkering is a huge component of this hobby. Thanks! That's pretty much how I do it. I have added another T to that which makes it easier to load, I will do some videos some time, still settling in to a new house. https://www.spudfiles.com/download/file.php?id=29108&mod...

Some welded tube on Mcmaster Carr has pressure ratings, but not that high.

I've had that happen before, I put a T near the end of the magazine tube and supplied it with a small amount of air from the barrel (another T)
Sort of like this
