Re: Remington 7mm-08
162gr SST/Amax over Varget/H4350. If you can get them to shoot sub MOA, then your max range will be this side of 800yds. That is probably a whole bunch further then you would wish to shoot.
Now that accuracy is under field conditions, not a comfy bench rest and still conditions. As the conditions or rests get worse, reduce your range dramatically.
Only practise will tell you what you can realistically do. More importantly then the most expensive scope is a good range finder. Without the ability to range reliably, you are sunk.
