That's one I always hoped to get into but never did. I ran across one back in the 80s. A guy who used to frequent the local gun range had an XP with a full bull barrel in .30 br. I don't recall if it came from the Rem Custom Shop or if he had it done elsewhere, but it certainly had my attention. It was center-grip design and had a gorgeous finger-groove stock on it.
Back then, XPs on the used market were fairly inexpensive. I wish I had the foresight to buy up a bunch and save them. Nowadays, one would almost have to mortgage the farm to get an XP-100.
