Interesting to watch the second lot of pellets in flight the 3 'wild' shots seemed to oscillate whilst in flight.
I did some testing on Sunday morning as there was so little wind a 8am and ave me a chance to test groups of sized pellets at 50yds. Found that 4.50 sized from a 4.52 tin worked well in my Ripley AR5s but did notice that there were some pellets that 'fell' though the 4.50 sizer straight from the tin. So it looks like I have to do check none of these get in my competition pelelts then.
Best result I got using weighed pellets between 8.35-8.55 was 6mm in height and 25mm in the horizontal measurement (slight breeze moving the pellets each side of the centre line).
