How many 270WSM barrels have you burned out????bigbull said:I use both of these calibers and would suggest the 6.5 over the WSM only because it is easier on barrels, if you don't intend to do alot of shooting then the WSM has it all over the 6.5 with a flatter trajectory due to it's much higher velocity.

It qualifies because the regulations specify a rifle of a bore no greater than .275. Bore factor not bullet diameter is the determining factor.mark k said:Wouldn't a .270 WSM not qualify for southern Ontario because it shoots a .277 cal bullet?
I'm burning 65 plus grains of powder per shot when I could be using less than half of that with a .223 or more than a third less with a 22-250 and still get all the performance I need in a varmint rifle.
