Sure I think there are many inherently accurate cartridges out there but you won't see the difference unless your comparing identical rifles and even making identical rifles is pretty much impossible. I think pretty much anything made on the 308 case the 250 savage case, 270 win,300 win mag,300wsm, the ultramags can be extremely accurate and shouldn't be too hard to work up loads for. I am not getting into benchrest cartridges because I know nothing about them other then stubby cartridges do very well.
