I plan on having the barrel on my Rem 7600 .243 cut from 22 to 18 or so inches.
I had an idea - before I send the rifle to the gunsmith, why don't I cut the barrel inch by inch just to measure the impact on velocity. This way I would know how much I lose and maybe even go shorter than 18 inches. If I lose 20 fps per inch, I might just as well go to 16 1/2 like on the Rem 7600P .308 rifle.
The cuts do not have to be neat - as long as I hit the space over the chronometer it will work. The gunsmith will make the final cut and re-crowning anyway.
But I don't want to blow up anything.
What do I do? Just cut a piece off with a metal saw or a cut-off disk?
