    Default To lube or not to lube....

    .. that is the question.

    Initially I noticed very slight tightening of my groups with lubed pellets. Nothing to get over excited about, but then again an increase is an increase.

    Shot some unlubed pellets this last weekend, and the grouping seems even better.

    Shot a fill each of lubed then unlubed pellets from the same tin.

    Any idea's as to why this is the case, reversed as it is?

    When you lube pellets, all you are trying to do is reduce the coefficient of friction. On certain barrels, Anschutz for example, you may well be wasting your time, as the design of the barrel already produces low drag characteristics.

    If you want to see what is really going on, clean the barrel thoroughly and then shoot some test groups with un-lubed pellets. Now clean the barrle again, and do the same with lubed pellets. If you now go back to un-lubed, the inside of the barrel is still benefitting from the lube, so you should still see improved groups.

    To sort out whether you need to lube or not, you need to go through this process ( boring though it is) a couple of times.

    Just as a matter of interest, I always lube my pellets. I have tried a few different lubes, they all seem OK, currently use Napier lube, because it works and over here it is very cheap. I suspect sewing machine oil would be just as good, but I've never tried it.

    Avion,
    I'm going through the same exercise.(ongoing for a year)
    will in future do my test as follows :
    1. create 2 batches of the same pellet/tin - eg 100 each
    2. wash both (if accucrap hahaha)
    3. lube the one
    4. test the lubed one on lets say 35m in groups of 3 shots on say 10 targets
    5. pull clean dry patches through the barrel so that the barrel is dry
    6. do the same test with the "clean" pellets

    Sometimes I also swap to dry pellets and get the same results (if not better), but that might be because the barrel is still lubed after shooting the "treated" pellets.

    Interesting, however I'm a little unsettled about my case.

    What with the barrel condition being constant.
    I shoot lubed and groups open up.
    I shoot unlubed and groups tighten.

    Do you think this is a case of too much lube then?

    Could be. I use three drops of Napier on 500 pellets.

    Either that, or you rifle does not like lubed pellets.

    What rifle? what pellets? what lube? what velocity?

    What a lot of questions !!

    Heh - true - sorry forgot about people that I don't shoot with - my apol's.

    S400 Carbine
    12ft/lbs
    AA Fields 4.52's.

    I don't lube a whole tin. I apply a few drops to an empty tin, then lube what I think I'll use in the next day or so (pellet amount wise).

    I would have said the 400 would be a little better with lube, but then it IS a little warmer over there, and that will have a bearing.

    Jenkinson has his pellets almost swimming in oil, but I don't know what he uses, some weird mixture he cooked up on the stove I expect %-6

    I guess you need to do the experiments and find out.

    If you use a bore cleaner, then remember that a raw barrel can need up to 20 shots to settle down again. When the pellets are back on the cross hair, you can start to play.

    Any excuse to do more shooting, Love it 8)

    is there a point where the lube just gets two much inside the barrel even with three drops per tin, i always worry about that so i run my air arms dry. or does theescape of air through the barrel kinda clean it? as lube would obviously create a negative effect is over used.

    I dunno Sven - hopefully will get some time over the weekend to play around with this. All I know though - is at this moment my rifle seems to prefer non-lubed pellets.
