Can tell you a little bit about the 270 Win. In my experience excellent cartridge for deer sized animals. I have killed eleven whitetail bucks with mine, and all of them have been very clean kills, the one that has runned the farthest has been 20 or 30 yards. Shooting 130 grains bullets is really effective for short ranges, up to 300 yards. If you want to shoot long ranges, you might consider start reloading and using bullets with a higher BC, like bergers VLDs, in 140 or 150 grains. I have had good results also with the Hornadys SST 150 grains.
The last factory ammo that I used that I liked was Winchester Supreme E-tip in 130 grains, after that has all been handloaded.
I have only heard good coments on SAKO rifles!!!
Hope this helps. Good luck with yours.
