SOCOM Looking at .260 Rem and 6.5 Creedmoor Sniper Systems

[Randy99CL]

So, I take it that 260 Remington will fall in popularity and 6.5 Creedmoor will rise, making brass more available. I am considering these in a Savage bolt action barrel.

I don't think getting brass for either will be a problem for decades to come.

I've been comparing these two, too. 260 Rem case holds 3.32cc, 6.5CM is 3.12cc almost no practical difference.
260 Rem not as readily available; some of the rifles I like are in 6.5 and not 260.

I've gotten impression that 6.5CM is more efficient? More powder in 260R doesn't give equivalent increase in velocity??
6.5CM may be inherently more accurate???
