[QUOTE=CapDog;334316] if you plan on shooting 140gr bullets in the standard Rimington mag you do have to seat them pretty deep and loose out on some potential case capacity. If you have an aftermarket mag system it's not as much an issue.
This is true, and it is the very basis for the 6.5x47L as well as the 6.5Creedmore. To better a 223 or the Grendel in an AR15 or short magazine platform(High Power competition), for medium ranges.
I respect no more of a 6.5mouse, than I do a 30br or a 6PPC.
These are not long range cartridges. They are not hunting cartridges.

Great Post. Good question. Seems like we could be burning some brain cells on this one.
In my opinion, shooting rock chucks has a lot more to do with benchrest shooting than big game hunting.( Hunting big game involves bigger targets.) Many 6.5mm bullets will do deadly damage on antelope, coyotes and chucks. So it's a toss up between them. The choice boils down to 130 or 140 grain bullets @ 3000 fps.
So look at your ballistic tables and choose a bullet. Any bullet you pick is going to work, just some better than others.
Next, all of these cartridges will launch high BC bullets @ 3000 fps. If you go much faster you'll loose barrel life. So learn to range your targets and get a scope that will do the job.
Next the choice boils down to brass. Why brass ? Considering the extreme accuracy that you'll need for long range paper or critter targets, you'll need the very best ammunition that you can get. And this means top quality brass. Most benchresters agree: Lapua is the best.
I will put Nosler next in line, then Norma. But clearly, all very good brass.
So pick a high BC bullet, pick a Lapua brass caliber to launch it, pick a barrel maker to build it and you're done.
While it does nothing excellent, it does do it all..
Can be very accurate
Varmint bullets as well as any other
No fireforming or special reloading
Plenty of suppressors designed around it
