Shooting 9 arrow ends.....3 x bareshaft,3 x each size vane in random order on a portsmouth target face at 20 yards.Shot about 10 ends
40mm vanes closest to bareshafts.In my case the 40mm were grouping on right edge of bareshafts and bigger vanes were grouping on right edge of the 40mm group.I shoot my
a/c/e's slightly weak and usually have daylight between bareshaft and fletched arrows with spinwings.Not so with the 40mm kurlies.
My understanding was that smaller/lighter/less stiff fletch would move arrow further away to the right of bareshafts(in my case),if anything.My understanding was also that smaller/lighter/less stiff fletch would be useless indoors but they working at the moment.Perhaps 40mm fletched arrow at 20y behaves too much like a bareshaft so travels in a very similiar way.Perhaps 40mm kurly are what you might call negligable and even too small or even the limit of what is correct for my arrow.Sometimes i shoot better groups bareshaft at 20y than fletched arrows.Reading this suggests that i may have to do things wrong way round.Smaller fletch at short distance and bigger at long.I is a bit confused
I still have same arrows and need some shooty excercise/practice,so i'll shoot some more 9 arrow ends at 30m on Saturday.That could amplify things further.
