I didn't realize they are that long I don't remember the length between the two been awhile but 100 % agree 7 saum is awesome caseLots of people are shooting a 7 saum in a SA, the 151's are .1 shorter than the ELDm 180's. Depends on what you want to do with it. 6GT is a competition bullet to me. 7 Saum would be a hunting and LR round, look in the reloading section you'll find lots of loads and speeds for the 7 saum. I wouldn't want to carry a McRee chassis hunting, they're heavy, had one on a savage in the past.
