As pretty well everyone else has said a .308 will be fine with good placement and bullets. If this were my son I would be ready to back him up the second he shoots with something big and would advise him to pour the lead on after the initial shot and you should do the same.
things can happen fast when an excited 12 year old pulls his shot, and a bear can cover a lot of ground in a short period of time. take no chances here as a mistake can be far to costly. the experience can be extremely rewarding and worthwhile, or tragic. also, screw the politics, like i said the experience can be extremeley rewarding. my son at twelve was an experienced shooter but i still watched as he missed his first deer four times (she was very obliging) at a range of seventy yards.
If you don't have a tag, it's illegal to shoot at an animal in BC. No "party" hunting for grizzly here.
LOLThe 180's or 220's will be fine unless the Grizz has been online and found out that it's supposed to be impervious to anything less than a .577 T-Rex
God only hope. If captain Kirk can screw alien #####es... your son can too....Are you sure you want to go through with this? If he gets a grizzly at only age 12, you probably condemn him to needing to hunt Africa by the time he is 30, and off-planet by the time he is 50. What a rat-race his life may be to pay for all that!
Seriously, though, I don't have the experience with the premium bullets to offer any advice on that, so I'll just wish you good luck for the hunt.
you are right they are sierras that i have in 220, probably going to lean towards the ttsx's though. Thanks
Your post was edited for recommending to do something illegal. Please read the rules again if you need to.
Commence Shelling...and would advise him to pour the lead on after the initial shot and you should do the same.
