[QUOTE="codyadams, post: 1239693, member: 87243"] The difference between a 130 and 140 berger VLD Hunting is very small. If you get say, 100 fps more with a 130 than a 140, at 900 yards it makes a difference of .1-.2 MOA for a 10mph wind, with the 140 being slightly better, if the 140 is 2950 and the 130 is 3050. The 140 also has more energy than the 130, but not really enough to make it hugely significant. The problem is, you may not even get the 130 to shoot acceptably in a 1in9 twist, Berger recommends a 1in8 for the 130's. Or, you may. My dad has a 6.5x55 that he is shooting the 140 Hybrid in and it is making bug holes, and its a 1in9 twist. Granted, we live at 6600 feet elevation. If you are low elevation, you may not have such luck. When building a custom rifle, you want to stack all the odds in your favor that you will have a shooter put together, and have it be exactly what you want, that's the whole purpose of building a rifle. Depending on where you live, you may be able to get the 140's to shoot in 1in9 twist, or it may not even shoot the 130's well, and you will have to stick with a 120 class bullet, which is starting to significantly limit your rifles ability to be the best it can in that cartridge, if you intend to really reach out there. Not saying a 120 won't kill things really far out there, it's just that a 140 would do the same thing, with less wind deflection, giving you, the hunter, a better chance of success. Bottom line, if you want to build a rifle one time, and do it right, hold off on the 1in9. Get exactly what you want, a 1in8 twist, and you will have the highest chance of being able to shoot the 140's accurate. I have a 1in8 in my 260AI, and it shoots the 140's phenomenally. I put together a fireforming load with a 100 grain A-MAX, and it shot under 1/2" groups at 100 yards, and killed p-dogs with authority. In other words, a 1in8 twist is much more versatile than a 1in9, you can shoot all weight bullets offered in the 6.5 caliber and more than likely they will shoot well. You may spend a couple hundred bucks more on getting the exact barrel that you want, but you won't be wishing that you had done it on down the road.
