I have a friend build one who don't reload ,so today i worked up some loads for him , this rifle shot amazing well with the first test load i made, it is a nice pleasant round to shoot, but in all honesty i dont know that it is much better or different than a 243 win , i loaded Berger Hybrid 105 gr bullets with H4350 powder , He has a small fortune in this rifle it should shoot as good as it did for what he has in it, But it was fun loading something different
