Looking for a good starting caliber for my kids to hunt with. I am looking at 260 rem or 6.5 creedmore calibers in particular. Used mainly to hunt mule deer. From what I have found it looks like the 260 has a little more options for reloading and the 6.5 has a better designed shoulder (don't completely understand what that means though) every thing else seems to be almost identical. will be shooting 140gn Accubonds most likely. Looking at either savage trophy Hunter, tikka t3 light, or ruger American rifles, want something lighter with not a super long tube for easier carrying for my kids. Looking for all info/opinions. Thanks
