[QUOTE="MontanaRifleman, post: 919556, member: 11717"] First, IMO, there is no such thing as a "more accurate" case design/chambering than any other case design/chambering. The biggest factors in accuracy are quality/type of rifle components, quality of smithing and rifle build, and load quality/consistency. That said, in theory, smaller case and lighter loads are less susceptible to barrel harmonics and this is probably why you see BR shooters with cases like the 6ppc and 6 BR. However, larger and higher BC bullets at higher velocities are less susceptible to environmental conditions. In a no wind situation, the 6 BR "might" out shoot a 300 WSM @ 1000 yds, but in a wind situation, especially variable, the 300 WSM will have the advantage. A lot of factors to consider when you are talking accuracy. Anecdotal stories of my 257 Wby shoots bug holes, etc., don't mean that on average they all shoot bug holes better than any other rifle. Next, in my 6-284, 61 gr of RL33 is about 100% capacity with a bullet seated near the bottom of the neck. There is very little room for that case to be improved and I don't see it gaining any more than maybe 3 gr of powder space. IMO, not worth the effort and you will end up shortening the neck which is already not long. [/QUOTE]
