Does anybody have any load data on a 300 win mag for the 220 SMK. Any help would be appriciated. I am shooting out of a 26" barrel. I was shooting the 180 SST but would like to have more downrange energy.

I use Berger VLD'S, but am intrigued as to why the MK248 mod 1 300WM is loaded with a 220 SMK?
Is it cost, or do the military have some other reason for this choice?
I'd happily use 220 SMK's, but on ballistic charts they seem inferior.

Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1

The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
