Proof Testing a .54 TC barrel

[LAGS]

One thing I would recommend if you want to Proof Test your barrel.
Do Not proof test it while mounted in the stock.
The double load will crack the stock.
I made a cradle out of 1x4 pine and poplar I had laying around.
The firing mechanism was made from a hammer off an old lock.
The set up I built to fire the hammer worked good , but just needs a little heavier main spring.

If you ever have to do this again you may want to consider model rocket igniters as a firing source. No lock needed.

It is funny you mentioned the model rocket igniters.
Back when I made some barrels for muzzleloaders back when I was very young.
I test fired them using rocket igniters.
But that was when I was a kid , and making barrels out of steel pipe I found.
I also used firecracker fuses to test the barrels.
I got that idea from an old western movie I saw , and the blacksmith used them to proof test pistol barrels he was forging.
The barrels back then were strapped across an old car tire to anchor them down.
The steps we have taken in our lives.
But I have a higher skill set now , and a little more knowledge.
But going Back to Basics could be a good starting point for many.
