I like to hunt with a Handgun, it is more "sporting" to me, and suits the way I hunt, my hunting mate, and greatest friend and I hunt 3-4 times a year for 3 days and do the following.
He uses a Remington 20" 7600 pump action 308, open sights, and can hit a coke can at 200 yards off the shoulder, I cant. Our sons come along most trips and they range in age from 10 to 16 yrs, the two younger boys both use 22lr bolt actions with open sights, my son uses either a 22lr bolt action or his (mine) remington 223 7615 pump action, fitted with a 3.5 ACOG. fast handleing and real easy to shoot with that set up.
I feel that there is enough rifles along for the trip, so my 25-06 stays in the hut, and I take a 6.1/2" 357 ruger Blackhawk. open sights, carries real easy, fast to get into action, and I have no trouble hitting goats on the move after the boys have run out of range for head shots with the .22lr's.
We take turns at shooting first, but the boys get a pretty good go, so its nothing for me to walk all day and fire two shots, I dont mind at all, the fun the boys have, teaching them how to stalk in, with a group of 4-5 people, this can be a real art, getting them close enough for a safe head shot with the 22's is some of the most enjoyable time you can spend with the boys.
I love my Ruger 357, I have several rifles to take, inc a 223, 25-06, 308 but dont bother most of the time.
Get some range time with your rosco, make sure you can hit 6" plates at 60-75 yards every time before you go out hunting, this will give you the confidence to make a clean shot when the time comes.
Enjoy yourself.
