    Bisley Magnum - Pellet weight

    Can anyone give me the weight in grains of these in .177 ? My version od chairgun v1.9.8 says they are 8.0 grns but I thought they were heavier. 8.0 is more like AA Field but the Bis Mag are a lot more meaty in the skirt etc..

    Cannot check the output in lb/ft without it - cheers

    Thanks Tutchi - I thought the Chairgun was wrong on that one - funnily enough I seem to remember it was 10+ on previous versions of the programme.

    Have a good Xmas, dgg

    I've always used 10.5 for Biz Mags in .177...

    So who's right?

    Lots in .22

    Some in .177
    I think and therefore...... I refuse to steal someone else's quote to try to sound more erudite or profound than I actually am.

    Question is, does anyone have any pellet scales?

    Second question...

    You can guess what that'll be

    Yes m8, and I've weighed thousands of .177 Mags, findings are they are one of the most consistent pellets available. 10.6gr is the figure to use.

    They don't work very well in my EV2. The EV2 breech does not have much taper or run in so any pellet that is a tightish fit risks being damaged on loading. Despite the utmost care during tests the Bismags gave group sizes about twice the size of JSB Exacts.

    I had a set of lab scales until recently, BisMags were very consistent and weighed 10.0 not 10.6...

    Incidentally, AA Field and JSB Exact weighed 8.4 grn on the same scales. And H&N FTT 8.6 grn.

    Hmm. Well, I'll just guess at 10.3 then

    that weights 10.6 are off the Bisley advert and both the prems and the mags are shown as that weight. On .6 of a grain you would have to have real sensitive scales to argue with Bisley.

    They weighed to within 0.2grn!

    My point really is that the scales agreed exactly with the published weights of AA Field, JSBs, and 177 FTTs - so there's no reason to doubt the accuracy of the scales.

    Pellets don't always match (or even come close) to their published weights. For exmple, 22 H&N FTTs were all over the place (pellets in one tin varied from
    14.0 to 15.0 grn!) and one of the RWS pellets (can't remember which) were also half a grain less than the published weight (177).

    Published weights are unreliable. If you're power testing you need scales if you want any kind of accurate result.
