Which WSM caliber for 400 yard whitetail hunting.?
I've decided on the browning x bolt for my first deer rifle but where I hunt I will be able too shoot 400 yards max. I like the Idea of the short action but I cant decide to get the rifle chambered in 270 wsm, 7mm wsm or 300 wsm. I will be hunting mostly whitetail and I'm going on a caribou hunt in a few years I will also do some antelope hunting in the future.
my only concern that some of my research shows that wsm calibers aren't that accurate and I will probably only be shooting factory ammo.
what kind of accuracy do you get with for browning x bolt and can I expect less than an inch 3 shot groups.
270 WSM gains the most advantage over the "standard" 270 cartridge, compared to the 7mm or 300, in fact loads out almost exactly like a 30-06 for powder loads and gets some really good ballistic numbers.

I would actually look at using 140-150 grain bullets to take better advantage of Sectional Densities and Ballistic Coefficients available at that weight range,and the ballistics would just get better. At 150 grains, both the 30-06 and the 270WSM match velocities within a few feet per second-and with the better BC and SD of the 270 bullet,you are looking really good at 400 yards (from reloading Manuals).
Now,as for accuracy,1.5 MOA is acceptable in most hunting rifles, and the 270 WSM should do that or better with the right loadings-again the heavier weight for caliber bullets "normally" group better too.
The big drawback on the WSM is cost, sometimes 2x the price of a standard cartridge. I reload for my rifles,and if you were to buy 10 boxes of factory ammo, that same money would get you most of the reloading basic equipment you would need for all your firearms. I'm reloading my 300 WSM for about $16 a box,with "premium" bullets,if I went with a different bullet selection (but still Bonded Core) the cost would be about $12 a box.
I'm reloading for my two A-Bolts in 30-06 and 300WSM (an older Hunter and a newer SS) and I'm getting sub-MOA in both. With the upgraded trigger group and better recoil pad for the X-Bolt a 3 shot MOA isn't out of the question by any stretch.
I do suggest reloading yourself,or having someone reload for you rifle if you go with a WSM cartridge. Craig Boddington is a big fan of the 270 WSM,and if I didn't already have the 30 calibers I would seriously consider getting one too. If you decide on a standard cartridge,it would be hard to beat the 30-06 with a 165-180 grain bullet for almost everything.
