Thread: Gunsmith for Barrel straightening

Is it a kink or a curve?

If its a curve then I would have a go at straightening it in the vice with padded jaws.

If its more of a sharp kink-bend the you will need a fly press and someone who knows how to operate said press.

I am actually not too sure. If you search for the clip you should find the older gent who was demonstrating the technique using a big block of timber and said barrel held by the muzzle and thwacked at the outside point of the bend over the block of timber. Was eye-opening to say the least. Bang, check, bang, check and twist, bang - pronounced good to go.

I've done the thwack job once on a gentle curve in the barrel. It is easy and worked well (thwack and check, thwack and check, ...) I followed the instructions on the web by doing it over the curve of the spare wheel off the car. The barrel has primary membory of where it was when it was straight and goes back to straight more easily than to bend.

H&K still doing ALL the 416 barrels hammer forged rifling and using the same technique to straighten them.
Most likely the same machine as in the Mauser factory considering they picked up the left overs from Oberndorf.
Bloody krauts!
