I built a 338-06 on an O3A3 action, in a wonderful piece of curly walnut Bishop that had been built years ago..Picked the rifle up as a 30-06 in a pawnshop in Idaho for $190.. now wearing a 24" ERSHAW ... took a real nice Mule deer Buck three weeks ago here in Wyoming, with a 200 gr Nosler balistic tip at 2650fps. He dropped like he was poleaxed.. the thing I like about the 338-06 is the capacity of the rifle... 6 rounds enstead of 4 in the 338winmag.. my load is 58gr of W760.. first load I tried groups at 1moa.. Just built the rifle in August... like it a lot..Les
