Thread: Which 6.5

Apologies if its been done to death, nothing showed in the search, so here goes.

So I am considering going to a 6.5 but which one? Most of the shorter versions seem to be trying to emulate the 6.5 x 55
260 Rem sounds nice but then as I see from other threads that there's several improvement versions.
So how about 6.5 x 284

What do I want to achieve.

Lighter rifle platform, most shooting under 300M but able to confidently shoot to 400 when needed ( not a game changer though )
Short barrel of 20 inches or less.
I like to reload so need to consider seating ability / variations which impacts on action length ?

Currently shoot 270, but these days I find it to be too much gun for carrying any distance.

Fire away with your options and opinions please.
