    Been doing some barrel cleaning experiments of late and have noticed that by sizing the pull through patch and oil changes including pull direction, it significantly effects the group sizes.

    Using Napier pull through / cleaning cloth I currently cut the patches at 52mm x against thickness of strip use a small amount of Napier lube pulling the patch from breech to stripper it will group around 40mm diameter at 55 yards.

    This was causing me concern so hence the trial

    I then reduced the patch to 51mm and using a mixture of pure olive oil and LT1 mixed at a ratio of 70/30 but this time pulling from stripper to barrel it vastly improves group sizes down to roughly one hole at 55 yards.

    Unsure if it's the 1mm of tolerance difference on the patch ?

    The olive oil & LT1 combo mix ?

    Or the patch traveling on a different axis down the rifling ?

    Any one else tried this kind of testing ?

    ttfn

    I shall be watching this thread like a hawk, Scott.
    Anything that can produce that sort of significance of improvement, has got to be worth following.
    Thanks for posting. :)
    I could beat Gilly with groups like that at 55yds :D

    It must either be the 1mm of tolerance or the change of direction ie stripper to breech.

    I can't really see that olive oil would make that significant difference as it's a lube in a sense , the LT1 has a slightly thinner viscosity than Napier .

    The olive oil was quite gloopy that's why I ratio'd it down with the LT1

    Gilly uses LT1 Jack so there could be a little bit of truth In his group sizes.

    Are Gilly's groups to scale? Think Gilly uses microfibre...

    I've found it makes a massive difference if you measure the 51mm across or with the weave of the pull through cloth also it seems to be better to use short jerky pulls as opposed to one smooth pull

    Try cutting into a circle,it makes a massive difference,a pellets round as is the barrel,why would you put a square down it:confused:

    Microfibre

    Microfibre?.... is that what small people use to improve their digestion and hence make them sh*te easier?

    April ?

    is it april already . if you are gonna clean from the muzzle end back .be careful , cos the choke is at that end . normally the patch will be sized down before it reaches the choke which is of course tighter . if using a fibre patch instead of 4+2 it could break in the choke . meaning rod time . not good .:eek: ???

    The real test would come from using different grades of olive oil. Perhaps also try sunflower. Best not to use oils that have been used previously for frying fish - the scraps could act as an abrasive. Suppose you could always filter first.
    Just some ideas.

    My groups have improved just thinking of all of the permutations.
    I'm going to go and clean my barrel before Woodend, in the morning. ;)

    Have you tried using a conker, I find soaking them in the oven and baking them in vineger works best:confused:

    All the best James

    James my Tin chicken guru , I'm having a scan on my left Conker on Wed, never tried soaking them in vinegar though ( once tried dangling them in sweet corn juice ) or ramming one down the barrel, although I have recently re-finished my stock with cumquat and sasperela oil.

    Like the idea though

    barrell cleaning

    used the vgf paste as per instructions, until barrell was clean, then for an experiment tried napier pellet lube on the pull through felts and they came out dirty, can,t shoot well enough to assess groupings, seems to me that I will use the pellet lube in the future.
