When I first recieved my 7mm AM, I worked up a load with a 160 accubond, its jammed .006 into the lands. Once in a great while due to differences in idividual bullets I would end up with a bullet stuck in the throat while unloading a live round, that was in 2006, now at a round count of approx 460 rds. I've never readjusted my dies and I still occasionaly pull a bullet unloading a live round. never scoped the chamber but I'm thinking throat erosion is very minimal at this point.
Though the 338 will last longer, I'm very happy with my big 7, and satisfied with its longivity considering its intended purpose.
Yes wildcats are available, takes a while to get them, and with S&H I think mine were just over 81 cents each. will try them when the weather breaks.
