You could try a sticky pellet powder but it depends on the size of the pellet. I've found that 4 and 6mm pellet scatter the worse because of the way they leave the pouch. As they leave, they hit each other causing them to spread over a wide area. It could also be a question of the pouch itself being too small, or using a catty for pellet that's meant for maggot/caster.
The catapult itself will make a real difference - I have a number ( different brands) but despite them looking similar / same they are very different. The pult I use for pellet wag is actually a none branded one but feels / works better than the others. Obvious point, but over stretching / a pult that lacks the power will be less consistent than a comfy 'lob' of the bait into the area. Try a few OR change pouch / elastics etc until it gets better. It might be technique also but the pult makes a huge difference
Try using larger pellets rather than small pellets 8mm is a good starting point.
Use a decent catty I use drennan and use the strong elastic red colour.....you won’t need to pull it very hard to fire the pellets out and you will be in more control......
I use the soft mesh pouch....... they have a string toggle for pulling the pouch back I’ve found that it’s best to actually hold the pouch and not the toggle and it does make a lot of difference to the placement of the pellets......
Don’t fire too many out 3 or 4 I find it better to fire twice or more rather than one big pouch full.
Hope this helps
Thanks for the suggestions I use 6 or 8mm pellets to around 30/40 M.and find I have more success with the soft mesh ones but don't seem to be a lot around for the bigger elastics ,probably technique but plenty of advice there to go at cheers.
Same as most of the other replys really, a decent catapult (I use an old drennan one), stronger elastic than you would think so you don't have to overstretch it, a good mesh pouch and not to many pellets. However once I get the carp feeding I don't mind spreading the feed over a larger area as it keeps the fish looking for food and I feel I get quicker and more positive bites than if the fish are sat waiting for the pellets to drop on their heads
Also how you hold catapult.
I fire mine almost upside down, grip handle with bottom three fingers and support arms with thumb and forefinger.
This prevents the catapult arms bending so only the elastic does the work.
Worst catapult ive had for it is the guru green one. Spreads pellets every where, the hard plastic pouch splits after one match and the elastic connectors break. Bought three and they all broke after 3 or 4 matches. Stick to drennan
