Two years ago I switched my .280 from 160 grain NP to 140 grain TTSX, couldn't be happier with the results. The 4 deer I have taken in that time have all died very quickly, 2 mule deer dropped on the spot, 1 whitetail taken on the run managed about 3 steps and one other mule deer managed about 5 steps. Meat loss was very minimal. These deer are not the large-bodied deer that you can get in Saskatchewan but I can't imagine the results would be much different given the same shot placement. I am thinking that 120 grain TTSX might work just as well.
I'm sure it will....I have killed more or less average sized bucks to super large variety with 130-140 gr 270 and 7mm bullets in Canada. They all died pretty much the same way.
I think something like a 280 with a 120 TTSX or similar will work just fine.In truth I can't see any much difference between standard cased 30 calibers with lighter bullets,and 270's 280's 7x57's,etc etc. They seem to be mostly peas in a pod.
The biggest whitetail in all of Canada is a pushover for a 270 Winchester.
