I have made some chum with Milo, but man is it hard not to get it all over your boat. My question is cattle cubes as productive? Cubes seems like less of a mess and no smell? Is there any preparation or just drop the in the lake?

Throw and go...don't use too much...sour milo works better though. Make u a chum chunker so you don't get all stinky. Good luck!

I use a dog food scoup my wife bought at wal mart. Holds about 4 cups of maize.

I use one of these from Home Depot. It will hold about a pint and can throw 20 ft or more.

Getting it in the boat is part of the game.

Cotton seed cake in a burlap tote sack brings them in. Can get it at any feed and grain store. Best of luck!
