I guess what I was getting at, in a roundabout way, is the 6.5-06 is THE stretch version.....
the prc and 'by284 are peas in a pod.
Yep, they peas in a pod, performance about equal, all three.
And, even though the shorter ones are a bit long, IMO, for a SA, like 2.9" COAL, they need to be in a LA unless someone has a 3" action.
The 6.5-06, of course, is a LA round.
My 6.5-284 is in a Pre-64, so LA. That gives me plenty of room for whatever bullet I want to use. I'm now shooting 140 VLD's over RL-17 at an honest 3K fps.

Edited to add, that's my 6.5-284 pictured over on the Swaro Z5 thread.
