Stop in for a cup of coffee

I don't have any guns and know pretty much nothing about reloading, but My son's likely future father in law reloads. Has a room in his pole barn with about any kind of shell. Alex got a 45 from his girlfriend for Christmas and her dad gave him 100rounds for that and 50 for his 38. He got a Mauser last year and he loaded a bunch of whatever that shoots for him...
nice, I've got a wall of dies, about 4 feet long, 5 feet tall, I can reload for just about any caliber I'd want too but only have so many calibers that I shoot
