Parker Hale 1200TX/M82 barrel profile

[Bladerunner]

Cinders,

I have never heard of rifling a barrel after it has been contoured. Can you imagine a lightweight sporter barrel or most profiles for that matter not twisting and distorting during the rifling process.

When a barrel blank is button rifled, the button is pulled (usually) through the bore, you need the rigidity of the extra metal to keep everything straight.

For the M82 profile, I honestly would not worry too much at all as it is really thick and heavy (>4lbs). Most of my barrel blanks are 1.2" diameter, so it won't take much metal removal to get to the M82 profile.
