I dont clean between shots and that is prob why i get some poor grouping. Plus, it gets pretty dang hard to put the following rounds down the barrel after a few. Next time out I plan on using a clean cloth to swab out the remaining residue to assit better grouping and easier loads. I know this really doesnt answer your question, so I will await someone with good shooting range experience as well. Glad you asked!
I swab wet with TC13, then dry patch and then lube patch with Wonderlube. I do this between every shot whether at the range or in the field. My theory is consistency. The firts shot was from a clean barrel so I try to have every shot after from a clean barrel
When at the range I want to know where that bullet hits with a clean barrel so I swab before I shoot the first shot and after each shot thereafter. I even do this in the field if time permits. I use an alcohol patch and two dry ones each time.
