[QUOTE="rooster721, post: 1061853, member: 40654"] Someone can correct me if I'm wrong, but I been under the impression 2800 is where BC testing/proving is done by companies such as Lapua (for their scenars) and is why MV of their loaded-ammo sold is in the 2775/2800 neighbourhood... That said, if Lapua claims certain performance based off those numbers, as well as life-expectancy in regards to barrel-wear and active duty out of each rifle shooting under these "load" velocities, then 2775-2800 is where a guy should try be. Lapua designed it to do/work a certain way. I would have to assume there's merit tied to 2800 in regards to that. I have mine loaded for 2775... 28" pipe, and see only the very odd velocity poke into low teens for spreads* There's a node at that velocity. In my own opinion, how hard you have to push a barrel to hit that node is only altered by length.. but generally speaking, the caliber itself should always perform good in that velocity-range... [I]whether a 20" 338 will ever hit that particular node is probably dreaming, so in those-cases a lower node has to be pursued and performance simply accepted for whatever it ends up being [/I] Point of the story is, 2800 is likely tied to the design and a general-node in relative barrels by design. And is why we try make 2800 in our rifles too, to make the most of what it's designed to do. This is my opinion. [/QUOTE]
