things have not changed over the years,,,,people think that you can get somone else to make everything for you,,,sometimes you gotta do it yourself or it dont get done,,,,it is nearly impossible to form a ctg case with a 40* shoulder (ooo yes some will say how about the 280 AI,,,the come bak is ,,,that is way bigger neck than a 6mm and smaller base line dims on the case,,),,,I used to make BR's bak in the day when 308 basic ctg were used,,,a 30-35* degree shoulder is about the max without loosing 50% or more to colapsing the ctg shoulder down into the case body,,,,I you cant do it with custom dies and one at a time,,imagine how tuff it is in the factory with its dies running like a Singer sewing machine,,,,not trying to fault any ones efforts,,,but they have never tired it or they would not be asking the factory to do it,,,,just realize that it take a little effort and skill ,,,just those with gunsmith and shooting/reloading skills will be able to make them,,,,the way it ought to be anyhow,,,Roger
