Well guys, as the title states its a 338/378 wby vs 338LM. Ive got my eyes on a 338LM Remington 700P but after talking to a few guys, they have told me im an idiot and should just get a 338/378wby instead. So, ive done a bit of searching, but cant find any thing that compares the 2 cartridges head to head. So, what do you guys recommend? It will be used for hunting deer upto 1000yards, and I dont want to build a custom gun. I also reload and have got a smaller gun in 300wsm. Can you get any commercially built long range tactical 338/378wby's or are they just custom jobs? Well, any input will be appreciated. Thanks!!
