30 deg angle rule
Can somebody clarify this rule for me
The un-supported kneeler should not be placed at an extreme angle (no more than 30degrees).
where is the angle to be measured from, is it the base of the peg ? as this will be different from the shooting position ,
is it measured from the top or bottom of the faceplate , from the kill or by pulling the string
how is it to be checked , will we require a test frame set at 30deg ?
