Greg, If a 50 is a must have thing with you, have you thought about a 505 gibbs shortened to work in a short action? It may be too big, to wide, to function thru a normal action. But there is no doubt it is big enough for a good shoulder for headspacing since that is what it is in its full length configuration. It may be too much trouble and expense. I will have to deferr to James or Marshall as the final word on this as I don't have any cartridge dimensions. Just a idea, Joey Sanders
