I only use the crimped loads, green, yellow and brown. I do not use the red although I have, they have just too much power and I am afraid that they will dammage the BB.
$5 at Home Depot vs $8-10 for the others form BB, Gun Dog supply, Dogs afield....
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.
I use the crimped ones since my original ones ran out. I see very little difference...maybe a little more power??? I don't use the red ones since it tends to knock the unit over...which usually I don't see since its hidden behind something until I launch the second one into the ground and see my BB launch itself through the air...
Doesn't bother the launcher too much but the dog sure gets excited.
The launchers themselves seem to be pretty durable.
I can no longer find the red loads at Home Depot, do they not make them any more? I mostly use green and yellow, the browns when working around too many houses, but like to use the red once in a while for really big throws, or throwing over cover into water for example.
