I guess I might be able to remove the spacer in the rear of the magazine to create more space for the long 7mms. I was looking at the Nosler cartridges but seems like they might be a bit too long to allow for magazine feed while seating them long? I have brass and dies for the 7RM which is a plus but I do not want to make that my deciding factor. Thanks for the input, I appreciate it.
