I just tried it on my 401. Cut the seams so you have one big piece. Cut into 3 strips the long way, rolled and stuffed. Held about 9-10 drops. Seems to work pretty good. And it made 3 stuffings per bag.

Each one after inserting I'd pull up the stuffing a little bit and strip so it was down in the cart about 1/8th inch or so.

At first I was thinking something was wrong because I wasn't tasting the burning poly.. lol
