Plastic cones for small baits
After many years of experimenting with catapults, I have concluded that plastic, cone-shaped pouches are best for feeding baits such as maggots, casters, hemp and small pellets.
This style of pouch keeps the feed grouped neatly, and gains the best distance. Most of these pouches feature perforations to help cut down resistance when you fire them, which is okay. But when using maggots, squatts or pinkies, you need to try to find a design of pouch with quite small perforations, or your bait will crawl out or get stuck in the holes.
Plastic cone pouches come in various sizes. The smaller ones, with small frames and light elastics, are very good for dinking out small amounts of bait regularly at short-to-medium range.
Standard cones are for more general use, or for feeding at distance, with medium-to-thick latex and beefier prongs and handles. You can get elongated cone pouches on catapults, designed for feeding lots of particles, but these are more for specimen and carp anglers.
