OK Tex, I have tried but I have yet to hit anything zoooming through the air yet.I think that any body, no matter how good of a shot they are, can hit a fork when wing shooting a fast moving target because of the fast fork movement. I always use a little wider fork when wing shooting. Also the pouch can move the shot by rubbing a narrower fork even with a good shooter if he holds the fork with out much movement. I have proved this on a bench test for accuracy several years ago. That is why I shoot a fork with a 2 and 1/2 inch dimension between the fork tips. Of course pouch size enters into this. My test was done with a 2 and 3/4 inch long pouch. Tex-Shooter
Hey JoergS, Is it possible for you to demontrate in slow motion video whats going on with fork hits. Might be a good study since it seems to be a common occurance.The right fork width is very important, as Tex said. Only very good shooters can manage a narrow fork without flipping.
And it is easy to figure it out.
If you have a draw of 1 meter, and shoot at a target 10 meters away from you, with 10 mm balls, and a fork width of 50 mm (all pretty normal dimensions), then you would have to deviate 20 mm from the straight line to the target at fork level in order to slightly touch a fork arm. For a full fork hit, you would have to fail slightly more. But let's use the 2 cm deviation for now.
Math has it that a shot that deviates 2 cm at the fork would be 20 cm off at the 10 m distance!
So if you
1) do not flip (those who do NEVER have fork hits), and
2) have fork hits
then maybe you are just not accurate enough for the fork width you chose.
I recommend (as Bill said) that you start with a rather wide fork. 12 cm (about five inches) is a good start. Then shoot. At the end of the day, look at your worst shot. How far was it off? Divide that number through four (for safety margin) and you have your safe fork width.
So if your worst shot was 40 cm off to the left or right, 10 cm fork width would be safe for you. With a 10 mm ball and a 10 cm fork width, you can miss by 45 cm and still don't hit the fork.
So you Milbro fans out there, shoot flipstyle! It has about 38 mm fork width. If you miss by more than 14 cm at the 10 meter target, you will hit the fork if you don't flip.
If you flip and have fork hits, then you aren't flipping right. This is the only explanation.
PS: The same calculation works for low hits and fork height.
