I just received my order of 250 375 Wnchester cases.It is beautiful. I can now put my fathers Winchester Big Bore 375 Win to work next deer season here in Tennessee. I'll also use it Hog hunting.All the cases are very consistent in length and weight. Now if you good people at Starline would add 300 Savage and 35 Remington to the lineup life would be great.
