RC, that's a tough question to answer and basically depends on where you draw the line on a bullet's terminal performance vs the game you are shooting. I use the minimal expansion velocity of the bullet as a limiting factor. With the SMK, there is no such published velocity. From some reports I've read on this site, it seems the 300 SMK will expand below 1800 fps. So the bottom line would be to run the numbers in a balistic calc to get *your* effective range.
Way farther than most can shoot effectively. It's hard far me to find a spot on the ranch in south Texas to max the edge out and it's 6000ac out in west texas no problem. i just dropped a 70-80# hog in its tracks at a 1000yrd with my edge. I would say edge 1500-1750 338am 1750-2200 just a guess on my part. probably has more to do with what speed you need to get your bullet to expand rightI didnt know there was that much difference. Does anyone know the max effective range on a whitetail with either caliber?
He does not have a website, but the cartridge descriptions in the link below should contain "most" of Kirby's line of long range designs.Does Mr. Allen have a web site? Looks like a person could send lead a pretty good distance with lots of knock down using his calibers. Thanks for all the replies.
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
Nightforce is such a solid combo of reticle, available elevation, glass that is good enough to shoot at the longest range you can dial. Nightforce has bullet proof construction that can handle the incidental horse rolling or some other rodeo action. -- bigngreen
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
