Re: 338/378 wby vs 338LM
My opinion is go with the 338 LM. Yes the 338-378 is faster but that is all you get with it. With the Lapua, brass quality is nothing short of PHENOMINAL. Woud you build a house on a poor foundation? If your answer is no, why would you build a load on a substandard peice of brass? Weatherby brass sucks. Not to mention wby rifles arent a favorate among most LR shooters because it is hard to find one that shoots worth a crap. Remington quality is less than wby but they still manage to make rifles that shoot lights freakin out. If you demand the fastest go with the 338-378. If you demand function and concistency, go with the LM.
I appologize in advance to any wby lovers out there.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
