They crammed it full so that it cocked like butter and would address the twang.Beeman used to sell “Spring Gel” which was a red, somewhat tacky grease. Probably very similar to this. I still have a container of it somewhere. When I sent my R10 to Beeman for a Supertune, they loaded it to the hilt with this stuff. It was very smooth and cocked like butter. Unfortunately after a little while it started dieseling. When i took the gun apart, the grease had migrated all over the place. Not sure why they used so much grease.
A quick fix at best as you found out.
