Hi kakali,

I know it wasn't one of your choices but if you are looking for all a 6-06 or 6.5-06 has to offer and more, why not a 6.5WSM? It can be built off of a long action.....It will offer better velocity than any of the others, the short fat case offers better accuracy. If you are concerned with burning up a barrel you can also hand-load a reduced load........I have wrestled with this for months and will be building a 6.5WSM.. At a reduced load it can offer 6.5x284 power and be taken way over any of the other choices by increasing powder.......Just a thought.............

Good luck
