[QUOTE="MagnumManiac, post: 2026600, member: 10755"] I convert 375H&H to 375 Weatherby one of two ways. I either fire form with COW (Cream Of Wheat/Semolina) and a fast pistol powder like Universal, about 1/3 of a max load in the PARENT case gets a good fire form. I actually use a load of 35gr of Universal under COW and a good tightly packed wad of TP. The other way is to neck the round up/down, as I did when making all my Weatherby cases from 300H&H, load a middle charge for the CONVERTED case you wish to make and shoot to get your brass. The beauty of belted cases is the fact you don’t need other steps, like false shoulders, the belt takes care of headspace just right. I have even turned 300WM into 270Bee when brass was hard to come by, never had an issue doing this. I even fired 300H&H rounds in my 340 Bee to get brass once...it worked perfectly. Cheers. [/QUOTE]
