Really like the look Stephen, curious, did that fluting have any effect on the shot group size or pattern?

Iím not sure yet. Havenít shot it. The barrel is kind of a ginny pig of sorts. I bought it to practice chambering on and have shot it quite a bit. I think it had 2500 rounds through it when I got it. Probly. 500 more. I had to recrown it after the fluting because the tailstock I was using deformed the the crown, not much but crowns need to be perfect. I is possible that the barrel could have warped from the work. I think it was button rifled.
The flutes are .05 deep done in one pass with a 1/2 carbide ball nose end mill.
I will get back what I test it out.
Thanks for the interest.

I tried Many years ago to do some straight fluting on a Barrel. Had lots of trouble with the finish (I used a end mill tilted at a bit of a angle and a homemeade wooden tailstock block clamped tightly onto the barrel end. I had the gunsmith tell me the Barrel was Junk and warped? Whatever, I didnt take much material out. I should of uses a slotting cutter? Anyways yours looks awesome Good Work.

I see from your description that you are using a series 1 BPT mill that you have upgraded. I need a saturable reactor which was used in the origonal drivers on this machine. Would you by chance still have some of theese older drive parts? thanks firstname.lastname@example.org
