[QUOTE="eshorebwhntr, post: 2877878, member: 17112"] Nice work. Def gave me the itch to try it and glad I did. Not near my notes right now but I got 16 or 17x firings before I noticed a hairline split starting to form above the belt so I stopped. This was pushing the 183 SMK above 3100fps with h1000. Primer pocket was still tight. I couldn't believe it. The 6.5x300 Wby is probably the way to go. Could also neck down 300 Wby. I ended up finding a 375 Wby die and that is the way to go in my opinion. It has much less body taper than the 375 H&H which reduces the amount the brass shrinks in length that first shot. My final process was 416 to 375 Wby, anneal, 8mm Rem, 7 STW, anneal, trim/chamfer/debur, load and shoot. Anybody that wants to use the dies to make their own let me know. [/QUOTE]
