I did all the calculations while examining those two cartridges a while back. I wanted the perfect ultra-lightweight mountain rifle to pack when I hunt in BC's mountain country. For everything from the smallest coastal deer - to the biggest northern moose, and everything BC has in between those two.
After months of comparing ballistic coeffecients, sectional densities, loading densities, barrel twists, bullet weights, etc. I came to a conclusion.
The 260 Remington was the best cartridge for such a rifle.
I put in my order.
Months later - they still couldn't get the rifle in that I wanted. But, it was mentioned that they had a 7mm-08 in the same rifle (1st generation Remington Ti) ready to ship.
I went back to my calculations, and found a few errors in my original cartridge comparison.
The 7mm-08 was, in fact, the ideal cartridge for my mountain rifle.
I placed my new order.
