[QUOTE="Muddyboots, post: 2065556, member: 63925"] Here's the question again. We all know the pressure spike from seating to lands but a lot of rifles cannot do so from mag limitations. So in this case has anyone actually taken a load, adjust CBTO/COAL by 0.005 and chronographed each adjustment in CBTO/COAL change? Pressure is not necessarily the only aspect of velocity changes. Sometimes load density versus case capacity can affect velocity due to powder burn efficiency. So sometime in next week or so I plan on taking a load and do this just for hoots. [/QUOTE]
