    Default Pellets

    hi All

    just a pic on the difference between the internals of the pellets, this makes a big difference in the "in flight operation of the pellets"

    also see the rifling grooves on the pellet, my question is how much affect does this play as the pellet is no longer uniform?

    Good Question ! We are being told by the big brains that damage to the skirt makes very little, if any difference to the performance and or POI. "Damage to the head accounts for erratical POI." Now what?
    IIRC all the above should weigh the same (8.44Gr ?). How is it possible, if some pellets visibly have more lead on the head side, while the walls seem to have the same thickness?
    I am at this stage not too concerned about which of the above pellet I use. I also use other well known names and some of them will surprise you with their performance. It seems that each one of them groups a little different to the other but are as good, once your rifle has been zeroed properly.
    I am asking the question: Are we not maybe all falling into the same trap as the power guys? ?If you use good quality pellets you will have good quality results?. I used one of the above this past Saturday and believe me; I had two flyers that had me miss the target by cms not mms. I know the shots broke well and with the follow through the cross hairs were still on the targets, I missed by a mile and very little if any wind. I am not implying that I am a great shot any longer, I know I messed up the other eleven shots I missed.
    The above happened to me with just about every decent (read expensive) pellet available in South Africa. Who has the time and equipment to weight and measure all his/her pellets? Horror stories about inconsistencies, I heard about the above, proved to me that most pellets will serve you well, some just have to washed.

    Accupells don't have to be dissected to prove anything. Just wash, load and hit the target every time. :jester Can you people still remember how lubricating our pellets suddenly made all our groupings shrink by 50%? :screwy I have swapped pellets with guys without them noticing and they didn't notice any change in their shooting. It is like my mother in law that reckons her car "jumps" if it is filled with Sasol. Bovine manure if you ask me. :flush

    Deformation of the skirt and head as in the above pictures will have an effect on accuracy. Well defined groves are good, lead flowing of the back of the pellets will cause flight problems, but then again if the amount of "flow" is consitent from pellet to pellet then they should fly to the same point of aim.
    The pellets have been shot through a barrel that is a thou of am inch or so to tight for the pellet. European barrels (ie German etc) are tighter than English made barrels and Chinese barrels are even more "open" (?) and that mite be the reason that they "shoot" so bad, but with the right skirt diameter they shoot very well.
    How do I post pictures to the Page again?!!! (blonde moment)

    Rifling marks will have no effect on accuracy. If there were marks only on the one side of the pellet then yes, it will have an effect. But because the marks are spaced out evenly around the pellet, no difference will be noted.

    Is it not like a golf ball effect ?

    Gerrie I think you have a point . A good pellet is most likly the way to go.Still think some rifles dont like some of them though.My BSA just cant use AA Fields.

    Found this site with a lot to say about JSB and Air Arms http://www.citlink.net/~schattler/ar1.htm

    Some more info on pellets just for interest sake:
    I went and did a quick weight comparison on some H&N Field Target Trophy and Beeman FTS pellets in 0.20cal. Afaik, the 2 pellet types are supposedly one and the same thing, right?
    I checked some skirt diameters as well and the H&N's averaged 5.02mm while the Beeman FTS came in at 5.03mm (as claimed on the tins wia sticker).
    Samples were taken from 5 tins each per brand, although I must say that the H&N's come in 500 and the Beemans in 200 per tin.
    So, in grains, here are the results with ave & standard deviation:
    HN FT Trophy Beeman FTS

    Ave 11.625 11.584
    StdDev 0.1195 0.0462

    I particularly smaak the smaller std.dev. of the FTS pellets.

    Spyker, the lead that is draged off the back of the pellet will affect the pellets flight, check the pellet pick that is scrolling, TS10 at 1005fps, good rifling but no degradation of the pellet.
