[QUOTE="Black Diamond 408, post: 90711, member: 1563"] When i got a look at the first 408 case several years ago i said to myself.."hmmmm, this looks promising!" I did build several 408's but in the back of my mind i wanted to wildcat it. I cut one of the cases in half to see the internals, very thick webbing! My first choice was the 375 cal, but no long range bullets. I moved to the 338 cal because of the 300MK bullet. I think in my opinion it would be a better project with the 375cal bullets, dont get my wrong the 338 shoots rather well. The 408 shoots good too, just no real match bullets out there YET. When Richard gets his dies then we will see what the 408 will do. He said 380gr up to possibly 450gn ULD's. These cases will take a lot of abuse and pressures. we have loaded some of the cases over 10 times with none lost. I think the case cap to bore ratio is better with the 375cal bullet. A 400grn bullet in 375 with bc's around .8-.900 would have to be outstanding for extreme long range shooting. Speeds around 2800-3000fps I wonder what twist rate will be needed for something like this???? [/QUOTE]
