Your rifles grooves are embedded with cosmoline, as far as the bullets you've fired are concerned they've been fired through a smoothbore rifle...hence the bullets tumbling when fired.
Loads of boiling water followed by a bronze brush. Finally clean patches etc...

yup think your right,so not going to kranks need brushes to get the cos out now,

When you've sorted it i reckon you'll be looking at getting 3inch groups at 100yds, if you do your part!

Bronze brushes will def be needed once you have most of the gunk out of the rifling but as it stands now will just pass through over the impacted cos. like the bullets did.

You need to use a combination of heat (plugged barrel and boiled water ) to melt it and loosen it - and repeat. Then some sort of solvent to shift it with patches. Then finish off as you would cleaning a fired rifle. When I did my Mossie I found paraffin did a good job of it - and it's cheaper than some other stuff in bulk. Acetone (nail polish remover) cheap at Tesco does a good mop up job after the paraffin.

guys
that all the wood off, well just the but to take off now

No need to do that mate, it'll be fine... Get plenty of boiling water through it.

well after many pours of hot water through it and fair bit of yellow crap, the pull through broke leaving the patches stuck in it a good un, and no suitable rod to fit, just gets better

God does this to make us cry - so he can drink the sweet nectar fermented of our misery. It's what gives him his awesome powers.

A length of suitable diameter wooden dowel tapped down the barrel ought to shift it.

Do you mean you can move the muzzle within the forend/top guard left and right and up and down? If so they all do that, they're mean't to. The No4 is bedded so that it has between 4 and 6 LBs upward pressure at the muzzle. So if you pull it up it should spring back and lie centrally in the bottom of the barrel channel.
