The 2014 UKAHFT Rules
are now available on the UKAHFT website.
The format remains unchanged & the rules have one small addition (highlighted in read on the Website) which reads:
The rifle butt must be outside your clothing when taking a shot & it cannot be supported by any straps/pockets etc, the only extra support allowed is during a prone shot where the bottom of the paddle/buttpad may be in contact with the ground.
We've not had any problems as yet with this but we have started seeing shooters tucking the rifle butt inside an open or partially open jacket so the above rule will stop this & any further developement along this line.
