I've been playing with an XP-100 chambered in .260 Remington, in preparation to having a long range version built, and finding I have a lot to learn about using these little hand cannons. Can anyone point me to a forum or book on how to shoot them (compared to a rifle)? I'm trying to shoot it like a rifle, and not getting consistent results. Questions like: 1. Are you supposed to control the recoil or let it jump? 2. How do you boresight, or even sight one in, even the muzzle jump is so extreme? 3. What's the "correct" form, arms extended or bent?
