, to get 6.5X284 performance with less powder and barrel wear. Rechambering doesn't require a new barrel and you can form Lapua brass (or any other .260 brass) from a standard .260 load.
Regarding the performance comment of the 260 Rem vs 6.5x284. Understand, Im not talking every rifle or yours particularly, but generly the 260 is roughly 50-100fps slower than the 6.5x284. Or it pushes the 130 VLD about the same speed a the 6.5x284 pushes the 140 VLD.
Now before I get a bunch of people chiming in, stating there respected velocities, I know many custom rifles will shoot with higher velocities than factory rifles. That also works for both calibers too. That being said, every rifle is different, and I know some are better performers (velocity) than the norm.....but they aren't the norm, they are the exception.
To the O.P....I think that the 7mm is the best all around per your request. Not as much kick as the 300wm but a little more knock down power than the 6.5s, yet still maintaining great ballistic performance. I personally love the 300wm as the kick doesn't bother me because I have a heavier gun.
You need to understand that the level of shooters on this forum (not me) is extremely high. They are very precise and educated people. To ask what one gun should be used for such a wide range of applications is a difficult question. A lot of long range shooter have a particular caliber for a variety of particular situations. I guess what I'm saying is there is no one caliber that's perfect. You will get lots of info on this site, take it all in, then go with your gut. You won't be disappointed because all the calibers listed are good ones.
