Yes, If you want to pay through the nose for it on an auction site. I have seen NOS factory ammo going for over $4 a loaded round, I can buy ammo for my 375 H&H cheaper than that. Only cheap way to shoot a 375 Win will be to cast your own bullets and load your own which is what I am doing. I got to shot this rifle today, iron sights only as my scope base is in transit, and I really like this rifle and the cartridge.
AMMO. winchester makes a run of it ever other year ive been told. one suppplier i deal with gets it for me occasionally. How i dont no. I ask him, with in weeks he has a box or two but it has slowed down somewhat. time for me to get him looking again. great great price and great rd for whitetails.
