My daughter will be 12 this November. I'm thinking of taking her deer hunting with my PSA AR15 because it's low-recoiling and with the stock fully collapsed it fits her well. I was thinking about trying to work up a 60 gr Partition ahead of a charge of Benchmark, but it sounds like I might not be able to find any. I appreciate the reports here of what else works in .223 on deer, my other option is to handload something mild for her in my 6.5x55SE, but that rifle is a CZ 550 American and I think the LOP is too long for her right now.
