A good system, if a little fiddly, there are two types of wad, one of them has a scrubbing wire in it,( obviously not steel!) I used to clean the HMR very regular, espescially the mod, it would build up with a muddy black sludge after around 50 or so rounds, LiL' Gun powder is notoriously dirty stuff.
I have bought them for my S&L rifles, in 243 and 3006. I was a little skeptical initially, as i am used to using the various potions and chemicals more commonly recommended. However they certainly work well, it is quick and easy and can do no harm, and i am not sure that some chemicals dont damage the barrel long term. If i remember correctly S&L recommend a deep clean every so many hundred rounds, but first impressions are they it is an excellent and easy to use system.
Never counted them lad, but as you look down the bore, while all seems nice & clean, you notice there are fibres left behind along it. Nothing very worrying, but enough. My last patch anyway is always a meths patch, so it does two things.
Takes those fibres away & leaves the bore free of any cleaning fluid residue.
