Hey gander, I'm using .530 Hornady balls. Not to get personal, but what size are your balls?

I've shot two five shot strings with the .530s and .018 patches without wiping the bore at all between shots, once back in April and once last week. Each time the fifth shot loaded as easily as the first. I'm sure I could have just kept on shootingmore shots without swabbing. Maybe it's the humidity down here softening the fouling? Here are the targets.
