mmmmm I used 150 grains on my 30.06 @ deer from standing 70 yards. I mean, I guess you could but you should try and take a head shot, A big one is 50 lbs lol. If you take a shot, keep distance with the 30.06. That's just my opinion though. And If I were you, be there in your spot before the sun even gets up and hunker down for 1/2 an hour before theres legal visibiity and keep your ears open more than your eyes.

I've had good luck with a 22-250 but of course always took head shots.

This past Febuary I shot mine with an 80 grain .243 at about 30 yards. A perfect double lung shot. She ran about 45 yards before dropping in some prickly pear cactus. The exit hole was small, as the bullet didn't expand much at all if any. You can find 30-06 bullet weights all the way down to a sabot 55 grain. I Don't know if I would do the 55 grain though. I'm sure it would do the job, but from what I hear they aren't very accurate. I think if I had access to a smaller caliber I would use a 223, 22-250 or 243 instead. A good excuse to get the AR out if you ask me. I opted to go for the Archery hunt this spring instead.

Good luck on your first hunt. I hunted the produce fields in Elfrida, AZ for my first hunt when i was 14. I work those fields in the summer and watch the pigs in the morning and evening. I used a marlin 783 in a 22 magnum for my first pig. The range was 30 - 40 yards. I lung shot him, he ran about 40 yard before collasping. I was too excited to listen to my Dad and I fired 4 more shots while he ran. I only hit him once with those shots and ruined some good meat in the hind quarter. Field dressed at 38lbs. I rambled to much, just enjoy your hunt. Good luck again & be safe.

Going this week. Sighted in my .30-06 @ 100 1"high. Took 3 shots @ 200 and was 1" high and 3" left and a 4" group. I'm gonna try to get close enough to take it with my .45 acp pistol and if I cant I'll just use my 06. Said screw it ang gonna use 180 grain bullet.
