Being In Canada I can get the t3 lite in 260 rem or 6.5x55. Hey are both 1-8 twist. I would use lapua brass for both and want to shoot 140 vlds. It is my understanding that the actions are the same length but different size mags are used and that the 6.5 is throated very long. I also realize that the tikkas are generally smoother and more accurate than rugers. I want to shoot 140 vld at 2700+ for northern deer. Which of the 3 rifles will do this in the best manner (accuracy, ease of load dev, brass longevity etc.).

I will mention that 6.5CM brass is rather difficult to get here in Canada (not sure even where yet) but if if can be made from some high quality brass I don't mind fiddling around to make some provided it isn't an unreasonable amount of work.

Thanks
