The WLR should be okay. Where you are, the temperature differential winter to summer won't matter. On heavy loads, with slow powders, in Montana in late November...cold, repeat damn cold, the standard primers I was using would give a "bap,Boom", with a low strike on target. Bad mistake. On big cases with slow powder in cold temps...stick with mag primers or the WLR. The WLR primers have a longer flame front for ignition of the Winchester Ball Powders. Just my experience.
I think that you will be fine switching, but my experience is you will see a slight velocity change. The 215 is going to generate more velocity, at least it does in my 6.5 SAUM.
I would of thought the 210m's would have been a better choice than magnums and BR2's my second . I've found velocities slightly lower with BR2's over 210's . ( 20 ft/sec ish in a 7 / 270WSM )
make sense 210 i think for litle faster powder and 215 is for slower saum powder..
