Well, I'm a little late to this party (just got back from the hunting lease).
Thirty minutes? Heck, I'll be standing in the driveway in five minutes waiting to be picked up. You are driving, aren't you?
In my right hand is my .50 Omega X7 wearing a 4X Simmons ProDiamond ready to be loaded with 105 grains GOEX FFFg under a 300 grain Gold Dot. Anything within 175 yards is in big trouble if conditions are right.
In my left hand is the TC Hawken with its .50 GM LRH barrel and tang peep sight. It will be loaded with 250 grain Gold Dots over 95 grains GOEX FFFg. I'll stretch that one to 125 yards - but no farther.
