I took three decent carp in the first 15 minutes of our match yesterday, on bomb & hair-rigged pellet across to a bay on the opposite bank.
Then catapulted a couple of pouches of 6mm pellets over the top, a tactic which has done well for me this year.
And killed the swim stone dead.
It took a couple of hours for the fish to return, then I did ok by putting in just 2 or 3 pellets every half hour or so.
