I hunted with a guy that did that this weekend (used ramrod with no jag). I don't know if it makes any difference, but It did make me cringe to watch him do it. If you already have the jag, I would see no reason not to use it. This "gentleman" also missed a target at 15 yds by at least seven inches (off of a rest), after bragging of his shooting skills at 100yds. So In general If I didn't already know any better at the time, I would do just about the exact opposite of this guy and feel pretty safe about it. Good luck!!
