Give the smooth twist section of the barrel a good clean, preferably with a soft brush to dislodge any lead at the start of the smooth twist. Eventual buildup of lead there will damage the head and skirt on the way out.

If possible, push a pellet through and inspect the head and skirt.

Also, you’ve recently had the loose valve rod issue. After tightening it up, you’ll need to re-adjust the valve until you get to same fps as before when it was shooting one hole.
