Yeah i was a bit amazed i did not see any lead.
It was just on a limb not like i had seem ny shooting deteriorate other than what i can with comfort blame on the wind.
I have shot pretty much all slugs in that period but those 3 weights primarily, even pushed 24 gr Zan slugs over 1000 fps and for the hell of it sometimes after shooting heavy put in a light to hear the super sonic crack.
Normally i " ram " a patch on the end of a CF rod down through my barrel, 5 - 7 of those do the job, it is only at the range i use my DIY pull through with patches on it, CUZ i can not be bothered taking off the barrel at the range for that, but at home i always do that.
I have for a while used 1" patched folded over a few times on a 3 mm CF rod, but i now use a 4 mm CF rod and 3/4" patches not folded over.
BTW later in the year i will modify the tip of my CF ram rod, i feel i can add a little ( spray lacquer or paint ) to get a slightly larger diameter and get tighter fit.
I think + 0,1 - 0.2 mm larger diameter will not harm.
Also ! i will get a box of the Zan painted slugs, but just use them as a shoot to clean solution,,,,,, well at least i hope so, they better not fly a lot better CUZ then my ammo budget go up
