No offense taken on my side. I don't know if you know this or not but the Sports barrel is a progressive twist, it starts out at like a 1-11 and ends up a 1-5 anyhow that's how I counted the revolutions when I counted it. But I do know that it is a gain twist and is made to handle all sorts of bullet weights. I personally have set at my shooting bench with a Colt AR15 H-Bar and a Bushmaster Patrolman and neither one is near as accurate as the Sport. When I first got my sport I got it as a fun under 100 yard toy. I had carried a 16a1 in the corps before I traded up for a M60 and qualified expert with all my weapons. Once I got to shooting the sport and it exceeded all my expectations, (no it is not a combat rifle and I wouldn't go to the sandbox with it, I would replace the upper receiver and then I would take it to the sandbox) and I don't know if its the progressive twist or the 5R rifling but it is far more accurate than any I have been around. Remington is going with the 5R in all of their top tier hunting rifles now. Also a lot of match shooters swear by the progressive twist. So this is where I come from. Melonite surpasses chrome lining in every category where it counts, wear resistance, corrosion resistance, lubricity, it wont flake or chip like chrome and it is a treatment not a coating so they make the barrel to the size they want and then treat it instead of over boring it and then plating it and reaming it where you never know how consistent the chrome layer is. I can link you to the engineering reports, not by S&W or associated with S&W to back up these statements. So now I have an 8-32x42 scoped tack driver. This week I took a Pdog at 262 yards measured with a laser rangefinder. I am having fun with it just seeing how accurate I can make it.
