[QUOTE="Brent, post: 26750, member: 99"] Sniper2, I was checking a factory load over the Oehler 35P last fall in my 300wm and a buddy had his there too. Mine was a 700, his a Ruger 77 mk11. Both had 24" bbls and his shot 125 fps faster on average with the same factory box of ammo. This has been my experience with Rugers though, they seem to get a little better speed than the others for some reason... all else being the same. His wasn't a Ruger was it? Theoretically, there is potential for some extra velocity, as some pressure is still behind the bullet even though the bore is larger in the brake and alot of pressure is vented off as it passes by the vents. The rifling is not slowing down the bullet any longer but, how much this ofsets the larger bore and progressive venting is anyones guess. A 100 fps gain in two or three inches of bbl is possible, but still a guess unless you remove it and then compare to yours. Did you remove it, and were they then both the same? Interesting. [/QUOTE]
