I removed the nipple and dribbled some 3F inside. Put nipple back, capped and fired. Rod came out just fine, but, I never found it. The range was a bit 'swampy' and tall grass in front of the shooting stations. They had a raised walkway to get to the target berm. Good part is I always carry a 'range rod' so I could continue shooting (after swabbing the bore).

I tend to shoot 5 and clean when shooting PP bullets.
