No damage. Just shoot it out. If load like 3 or more I would use a rod to push it out. Firing too many pellets at once can jam the barrel. But 2 is fine to shoot. But if you used a ldc or shroud that have baffles. Remove them to avoid clipping. Sometime I double load on my impact. I remove the ldc. But left shroud on and just shoot it out. No problem.
