I am working up some loads for my newly barreled Mauser in 260 Remington... 1:8.5 twist McGowen barrel. I like AMAX's and use 140 gr in my Swedish Mauser. What I was wondering is why Hornady makes two bullets so close in weight as the 120 AMAX and the 123 AMAX. Is it more than weight alone or is this something related to imitating the Lapua 123 Scenar? TIA
