I think the 170 grain does a little better than the wsm
out past 600. I’m not sure all weights it would commonly shoot beat the wsm. Another new cartridge with overlap performance where differences are negligible. But hey they got to sell things.
Besides short beefy cartridges with steep shoulder angles,burn less powder(efficiency), shoot high BC heavy for caliber bullets,with low twist rates; are all the rage.
