The Remington Model 7 and XP100 use the same action
The very accurate XP100 pistol has always used the same action as the Model 7. These are very good and quality actions. The Model 7 is lighter than the Model 700 short action due the rear of the action being smaller, even with the same bolt throw. The custom shop makes their full stock Manlicher using the Model 7 action, they would use the Model 700 short action for these custom guns if there was anything to be gained by it.
