I dont get when ppl say 300 wm is WAY more expensive than the 308's. For example, lets consider Hornady's: >308 Win 150 gr GMX® Superformance = 20/BX MSRP: $52.20 >300 Win Mag 150 gr GMX® Superformance® =20/BX MSRP: $55.37 > difference in ammo $= 3.17 >308 WIN 150 GR INTERBOND® SUPERFORMANCE®= 20/Box MSRP: $48.68 >300 WIN MAG 180 GR INTERBOND® SUPERFORMANCE®=20/Box MSRP:$51.87 > difference in ammo $= 3.19 >308 WIN 165 GR GMX® SUPERFORMANCE® = 20/BX MSRP: $52.20 >300 WIN MAG 165 GR GMX® SUPERFORMANCE® = 20/BX MSRP: $56.00 > difference in ammo $= 3.8 308 WIN 165 GR INTERBOND® SUPERFORMANCE® = 20/Box MSRP: $48.68 300 WIN MAG 165 GR INTERBOND® SUPERFORMANCE® = 20/Box MSRP: $51.87 > difference in ammo $= 3.19' So on average a 300, 20 round box costs around $3.34 more than a 308 20 round box of ammo. IMO that isnt a huge difference you'd have to shoot aprox. 16 boxes of the 308 20 round boxes, by which then you'll save around $55 dollars. Just a lil over enough to buy another 20rd box of 308s. So basically you wont really have a "difference" until you shot 320 rounds of 308's or putting that in a different way: you'll be asking your self if 300 win mag is worth the money after your friend has shot 320 rounds on his 308... I think its worth the money for the flatter shooting, heavy hitting, longer range ammo. how about you?
