id say it could be done, and a lot depends on how you go about it, if you kill 20 then jump back in the motor and drive for maybe 20 minutes to the next spot and get another 20, and so on, the dogs getting a bit of recovery time in between, i know a lot of lads lamp like this, obviously the dog has to be super fit, and have plenty of stamina, then the lamper has to know his job and be selective, then offcourse the ground has to be right and the rabbits have to be their in there masses.....
never been no where near 100 myself with the 1 dog, but i've had good numbers with heavy built bull cros
