Dugaboy1, sorry for being a thickie. Can you explain the rucksack idea as it sounds like a good one but I can't quite envisage the setup. weight is in the rucksack, you are sitting at a bench, rucksack on table, strap of rucksack around butt then butt into shoulder ? strap taut so when gun recoils it pulls against the rucksack ? Is this right ? best, Mike
