Honestly I feel to get the most out of the cm a guy has to reload. Or maybe should choose to reload. I’ve had mine for a few years when I bought it the options were bad. For ammo. Winchester match, Hornady 120amax,140amax. That’s it. I’ve loaded Barnes 127 lrx, 140 Barnes matchburners, 140 VLDs. All have shot sub moa with the proper powder charge. Mine likes 4451, hybrid 100v for 140’s and h4350 for the 127’s. I’m gonna try the 143 this winter..
