If they didn't come out with new rifles and cartridges then we would all be shooting a 30-06. Gee that would be a whole lot of fun. [&:] [&:] [&:] If we didn't have advances in technology and design then we would all still be living in the stone age chunking spears and eating raw meat.

It does have the same bassistics as the larger 300 but it is like comparing a light weight modern sports car to a older heavier muscle car.
