I started my Mk3 long range pellet testing today and one thing has really struck me.
I always imagined that the principle of faster pellets flying flatter was fairly foolproof but I've today seen a pellet leaving the barrel 50fps faster (1.5gr lighter) be very considerably more loopy at 50yards, due to it having a BC of .024, not .034 of the heavier, slower pellet.
Food for thought.
BTW I now sleep with a tin of Daystate FTs under my pillow <img src="http://jsramsbottom.co.uk/bbs/e/icon_wink.gif" alt="Wink" width="15" height="15"><!--graemlin:;)-->
Oh, I had the shifting zero thing on the Mk3 and sh&t myself that I'd knackered my scope or something but I LOOSENED the 8 clamp right off (it now does what it wants, acting only to stop me bending the barrel if i were to hit it hard by accident) and the problem has not reoccured. I had initially discovered it to be loose and tightened it up -perhaps I didn't line it up quite right at that point and pulled it to one side....
5p groups at 60yards today.
