I was asked a question yesterday at my that I honestly could not fully answer. UKAHFT rules state that the stock depth between barrel centre to the lowest point in front of the trigger (ie hamster) is 150mm. The question was asked about FT events/rifles is there a similar limit as the UKAHFT. I do not believe that there is but am hoping that I could get clarification on that from the estemmed members of this forum. Many thanks.
