As stated above the crimped loads will work fine. I also use the green loads from Lowes/Home Depot, about 5.00 per box of 100.
They will occasionally split a case, making extraction difficult, so I keep a small pair of pliers in the box.
Sometimes you will get a blooper load, meaning that the bumper does not go very far. If you get a bunch of those, I suggest you clean out the channel where you insert the load, with a .22 cal wire bronze brush with some Hoppes' cleaner on it.
I use yellow loads occasionally, and have had no problems with those either.
