Happy boy and a proud father, that kid will never forget that elk no matter how many he takes in his life.
To much reading about what bullet/caliber is needed for elk and not enough on shot placement. Sells magazines, guns and gives guys who have probably never shot one something to yat about. Uncle of mine got his 17 years in a row with a 30-06 using 150 grain bullets. I took his advice and have killed several with the same. Posted about that once here before and got blasted " not enough bullet et." Most important is shot placement IMHO. Looks like that boy put it where it counted.
