Re: Bandsaw?
Bandsaws run much cooler ( esecially when equipt with the coolant attachment ), my guess is to prevent heat damage to your barrel.

Re: Bandsaw?
That's odd. I'm wondering if by using the term "cut off" tool that they were refering to an abrasive cut off saw?
I don't see where putting the barrel in a lathe and using a parting tool with coolant would do any more harm than a band saw. The surface feet per minute of both tools should be about the same.
Interesting.

Re: Bandsaw?
I read a thread a while back on a benchrest forum on this topic. I do believe the manufacturer is refering to a lathe cutoff tool although I woulndt use an abrasive cutoff wheel either. The concern is that removing a portion of the barrel with lathe parting tool might alter the bore dimensions near the cut. I have never tested it so I could not say one way or the other but I generally band saw to lenght and then machine. I use two spider chucks to hold the barrel and Im not comfortable parting a section off from that setup anyway,so for me the bandsaw makes sense.
Here is a link to the thread I read cutting vs parting

Nobody would use a cut-off "wheel", right...but then again. I can see a material change on the surface from using a lathe vs. bandsaw. But nothing the crowning wouldn't trim off. I can't see It affecting the material any further than .1".

i'm assuming the cut-off tool they are referring to is also known as a parting tool for a lathe. i remember years ago reading about someone looking at the grain structure of the barrel with a microscope before and after cutting with a parting tool and a band saw. going purely off of memory of what i read, apparently the pressure applied using the parting tool rearranges the grain structure of the steel near the muzzle. since i usually part the barrel about .050" proud of where it will finish at, face to final finish length and then recess another .090", i'm not too worried about it. i have yet to have a rifle that wouldn't shoot to my standards using this method.
now i would certainly love to re-read that article if someone could locate it.
i while back i was searching for this article so i could re-read it but i haven't been able to find it again.
