Re: New to the long range game
Ryan, since you are looking to shoot beyond 700yds, I would like to make these suggestions.
First off, don't get a 308. I have owned and still own several. A wonderful cartridge but ballistically, not up to modern tech.
From a purely ballistic standpoint, the 6mm, 6.5 and 7mm are much much better in this case size. Suggested cartridges include the 243, 6mm Rem, 260Rem, 7-08, 6.5-06/6.5-284 ( readily available wildcats), and 280Rem. For lighter recoil and reduced shooting cost, the 223 and 75gr Amax will hold its own against the 308 and 175gr MK. A 22-250 simply puts it to shame.
Unless, you are shooting in a class that requires the 308, have a look at the above cals. Run the bullet data through any ballistics program and you will be stunned at the difference.
The reduced wind drift of 140gr 6.5 or 162gr 7mm can be measured in feet at 1000yds.
