I'm planning on taking my 11 yo nephew out deer hunting this year for the first time. I'd like to get him in the woods early and would like for him to be able to hit the woods during black powder season. I currently shoot 2 Triple 7 pellets behind a 240 gr XTP. If I shot 1 pellet or 50 gr and the same bullet and limit my nephew to 50 yards, would this be enough to ethically take down a deer? We practiced this at the range and he handles the load/distance great. I may try 100 gr during next range session but was wondering what you guys think?
