Re: Bore Tech C4..... A+!!
I have never used the v stix. I use the proof positive ones. I have a .17 cal, a 243-270 cal one and a 338 cal one. I don't have a .22 cal or a .30 cal rifle so I don't have those rods. They are expensive but they are super nice and tough. They won't give you a false copper reading either since they have a proof positive tip. I am sure that the v stix are very nice as well but I can't say for sure because I have never used them. I am pretty sure that I don't have as many rifles as you do so I don't have to buy as many different rods for the diff cals.
What I did was buy one of the nice proof positive cleaning rods when I bought some boretech solvent. Then when I ran out of solvent, I would order another rod for a different caliber when I ordered more solvent.
