[QUOTE="Black Diamond 408, post: 359973, member: 1563"] Its allways fun to mess around with wildcats but i am afraid you will be disapointed with the 375 on that big case, like Kirby said, there is too much case capacity for that bore size/bullet weight. It has allready been done by several guys in Australia and New Zealand with poor results. They have found the 460 Steyr is a much better fit, the larger bore helps the case breath better. The 408 case wildcatted to 375 is about the best fit for powder capacity and bore size. There is one other case out there that i have been working with some, the 585 African, Not Nyati. It is the next step up from the 408 case, same basic length only larger in dia. .688 base. I have the 416 reamer for it, results are similar to the 416 barrett only with standard primers and powders. Last time i talked to the guys in New Zealand they were going to neck it to 375cal. I expect that would be similar to the 338-408 wildcats for overbore results but only with the larger bullets. Velocity is unknown at this time for this chamber but the 416 version will push the 400gn bullets 3200+ I also have the reamers for the same case necked to 50cal, one rifle is in the works if the action ever gets finished. I expect that chamber to duplicate most 50cal loads in a standard rifle. Dave [/QUOTE]
