I plan on taking my 12.5 inch 6.8 deer hunting this year. It pushes a 110 grain SPH at 2440 fps. I can routinely get 1/2-inch 5-shot groups at 100 and 2-inch groups at 200. I'm wondering if I should even bother to double-check groups at 250 or 300. I did once and I could get 4-inch groups off improvised rests. Considering that any shots at this range would not be taken if accurate shots could not be made, do you think this would still be lethal and humane? I routinely shoot my AR-10 at 400 and 500 yards off improvised rests and can maintain repeatable 7-inch groups at 500 yards.

Some ballistic calculations shot the velovities at
250 yards would be 1800 fps
and
300 yards would be 1700 fps.

The deer around here don't get too big. There are an aweful lot of adult does that dress out at only 100 lbs. (I'm not a trophy hunter anyway.) It's just that there haven't been much around on my hunting land the last couple of years and some of the longer shots are the only shots I get.

Thanks,
JR
