Back 10-12 years ago a guy on long range hunting website built a 7rum with a 34'' Pacnor barrel on it.
Folks commented they didn't know barrels that long were available. A member chimed in and showed a picture of a 40'' Pacnor barrel , I forget the details of that build.
The 34'' barrel 7rum was a mean machine, it zing'd heavy for caliber bullets real fast.
It blew 7mm mag, 26'' barrel ballistics away.
