What's a "Thar"?.
180 VLD's at 72gn 2217 plus or minus a little depending on your rifle. Wouldn't be using Game Kings at 7Mag velocities(inside 300), unless you are being cheap and loading them slow, which would negate the whole point of going 7Mag from .308.If you must go Sierra for the cost, go to Prohunters instead, much tougher, better if you change weight, staying with Sierra, go to the 160 HPBT, it is tough and kills really well, the 175 Game King has better bc and will flatten just about anything at 600
Personally, I run 180 VLD's at 3000 fps(72.5 ADI2217) and/or 120 TTSX's at 3500 fps(70 ADI 2209).
Being cheap about loading for 7Mag is a mistake, the whole point is to wring performance from it, otherwise .280 would have been a much better bet. (As a budget performer, the .308 is nearly impossible to beat, so don't try!)
My .308 gets fed 130 TTSX's and 165 SST's and the SST kills them just as dead as the 7Mag at 600, despite being somewhat shy of the 7Mag's velocity and energy at that range.
