Do these cleaning pallets create enough resistance to keep from damaging your spring operated pellet rifle? In the reviews I have read their leaves to be some questions about this! Some folks say to stack them, some folks say not to use them at all?
if you are shooting a spring powered magnum air rifle, then this might be a concern. That's why some folks to suggest stacking them. Shooting in PCP/CO2 or less powered airguns should not be an issue. If concerned stack them!
