You can get a feel for how much pressure is in there by unscrewing it a couple of turns and lean on it, I put a pair of leather gloves on the end block and put the muzzle on a block of soft wood. You should be able to feel it move it the threads a slight amount when you have leaned on it enough and gives a good gauge as to how much pressure is in there. It’s normally harder to put it back together than getting apart.
