Tim,
Today is the last day of anterless season here in WV. I think I may take my 280AI and my 7 RM and let my son and grandson shoot a couple of does. I will also take my stop watch and see how long it takes the does to die. We will shoot 120 TTSX's out of the 280 and 150 NBT's out of the 7 Mag. I hope they don't bounce off. In case they do I'll have my 6MM Ackley with me to take care of any problems we may have. I could call my ex brother in law and he could use one of my 270's with 130 NBT's so we can see whether they will dispatch a doe too.
Not sure the 280 will be enough compared to the 7 Mag. lol
