[QUOTE="trebark, post: 412466, member: 19172"] Generally speaking, most general-purpose rifles come with 24" barrels, varmint rifles 26". Conventional wisdom on custom barrels is generally the extremes - some guys like 20" and others like 28" (the guys that shoot Palma matched like 30"+). It all comes down to your needs and preferences. Personally, my new 260 (308 necked down to .264) has a 28" barrel so that I can wring out every bit of velocity that I can. Of course, with that long barrel, I have no plans to take that rifle into a pile of brush. Although it might seem long to you now, from the sounds off what you're saying and the pics you're posting, I think 26" or 28" is the barrel length you're looking for. Either will give you good velocities and better accuracy than a 'normal' barrel. 168 is still a good bullet, but they do tend to lose it at about 900 yards. The 155grain bullets are what they shoot in Palma matches. In order to get them to go to 1k they have to push them at max velocities. That's why they like the 30" barrels. Because the 155grain bullets require a slow twist (1:13) it would pretty much limit you to the 155grain bullets. I would counsel you to twist your barrel a little faster (1:11 or 1:10) and shoot the heavier bullets like 175, 185, 190 and 210grainers. My buddy with a 28" barrel 308 with 1:11 twist shoots 208grain Hornady Amax bullets with 48grains of RL17 at 2650fps. It is awesome! I don't know who manufactured those rings, but I can tell you that the rail on top of the front ring is for adding accessories. In this case I would say it's for adding night-vision equipment. You can also get rings with rails on the side so that you can mount other equipment like flashlights, laser sites etc. You will also often see bubble-levels incorporated into the top of the rear ring.
