Thread: JW15 piece of shit

Would also try some different ammo as some 22's can be picky.

Common in older barrels to have off-centre bores. The art of drilling a straight deep concentric hole is deep magic.

Many barrels are manufactured with bores significantly off centre. The barrel can then be put in a lathe between centres and the exterior cut evenly around the bore. But in a cheap gun such cosmetic concerns matter little, unless you want to put a nice tight suppressor on like from Waitaki Engineering. Explains why my JW15's stock suppressor looks like it will let a 9mm through without baffle strike: safe tolerances for eccentric but otherwise accurate bores.
