Yup, it was still aching a week later when I did it's first HFT.
I started shooting the long stuff that day as I had shot most of the shotgun carts from 15 yards out and I was getting bored. I also managed to shoot some string at 20 yards that somone had suggested was for just that, unfortunatly after 3 direct hits in the same place, and cutting it, a voice piped up "who just shot my plumb. Bob?"
I owned up but felt very embarrased.
Good trick though
I'll try some long range groups when I get the chance.
Cheers
John
