First, I believe the predicted death of the WSM line, is a little
myopic. These things are very popular with the young shooters,
that like the word "Magnum", in the name of their cartridge.
Sure we crusty ol' Turdy O Six" guys have no use for them, but
the young rifle crowd, and even a few of the crusty guys have
picked up on the short fat magnums. One of the carpenters,
building my new home, saw my reloading room, and had to tell
me about his new elk rifle, and how well it performed out west
last year, on a couple of elk....It was a 270 WSM. Then this crusty
ol' Turdy O Six guy had to pull out a couple of load development
targets, and show him some sub-MOA groups shot with his
300 WSM :-) Whether we like it or not, these are the .30-06s/.270s of
the new century. Given the number of these rifles, I expect finding
ammo for the WSM line is safe for a good long time.
Now the 6.8 Rem, on the other hand, it remains to be seen how
long that one lasts. Remington does not seem to be hitting the
market hard with that one, so it may be dead, on delivery.
Of the three choices, stated, I also would suggest the .270 Win,
although the "not much recoil" requirement may not
be met with this cartridge. I would call it a moderate recoil
round.
I have to pile on the 7mm-08 recommendation. Somewhere
between the 7mm-08, and the .308 Win, lies the perfect, out
to 300 yard, deer rifle cartridge. If you want to shoot factory
ammo, then I would shade towards the .308 Win, since it
comes in a ton of choices, and is available everywhere.
If this is not a concern, and you prefer a slightly softer recoil,
and a touch flatter shooting round, then I would shade towards
the 7mm-08.
