[QUOTE="Joel Russo, post: 241369, member: 6152"] There are certainly pros and cons about having a barrel fluted after it has been lapped. Many factors come into play such as the depth of the flutes, the diameter of the barrel, the amount of material removed per cut, etc, etc... There is no doubt that you are changing the "metallurgy" if you will. I recently had a barrel fluted by a well known gunsmith after it came from the barrel maker. In fact the barrel had about 100 rounds through it before I pulled it, re-contoured it, fluted it then re-chambered it. It was a 34" 1.450", .338 barrel chambered for .338-.378 Wby. It shot well as it was, I just wanted to step up in horsepower. I re-contoured it to 1.350" for 5", then straight taper to 1.10" at 33", and put 10 flutes in it. It was re-chambered to .338-.408. I was a little skeptical about how it was going to shoot. Much to my surprise, it flat out shoots. It will routinely shoot .750" at 300 yds. Philny1 on this forum shot a sub 3" group at 750 yds, and I shot a 3.806" group at 1,680 yds at an IBS match in Ohio in the spring. I posted on that 1,680 yard group under the competition section. Did all that work change things around? I'm sure it did, but by the way it shoots, it appears as though it was for the better in my case. Just my experience with re-contouring and putting flutes in a barrel after it comes from the manufacturer. [/QUOTE]
