I have been reloading a while now and I know most of us on here tend to seat bullets longer to get close to the lands. I have followed this as well. For my pistols, however, I simply seat bullets below book max which is typically set to ensure the rounds will fit in your magazines. Well...how short is too short? The reason I ask is I have noticed my XDs 45 likes bullets seated shorter to cycle reliably. If I am near max length I get a lot of hang ups. So the question is...what issues can you face with seating too deep? The book states 1.275 oal as max length...how short can you go is my main question??? I know seating deeper can often increase pressures so I will watch out for that but anything else?
