Sakoshooter, I agree with your assessment of .25 caliber on elk. I think it's a good enough deer cartridge with the right bullet. I shot a .25-06 for many years. With premium bullets you should do fine. After all, it's the same cartridge case as the 270 and 30-06; just shoots a smaller, lighter bullet a bit faster.
Being a left handed rifle shooter I can relate to your dilema as there aren't too many LH rifles made these days. Remington makes LH guns. So does Savage. Sako Tikka is made LH also. My opinion on the 25.06 and .260 is that they are both on the small side for big mule deer with less than an ideal shot. Both shoot fairly light bullets even though there are numerous super premium bullets available today. I'd recommend a 30.06 or .270 for a good all around deer gun and the 30.06 can make a good elk gun with heavier bullets. Not trying to bust any bubbles, just my 2cts worth. Best of luck shopping.
