Although I didn't mention it before, so as to not deviate from the Raptor information being passed on, this issue is another reason I like GJ treated bores. I can leave my firearm fouled longer in storage because it fouls less frequently and the Gun Juice is offering some additional corrosion protection so I don't feel the need to come back and clean after every shooting event. Therefore when I grab the rifle to head out to hunt or shoot, the first shot fired is from a fouled bore over a GJ slicked up bore. If I want to check zero before hunting, the first shot should be on the money. I don't need to fire a fouler shot or two. However if you do feel the need to clean your bore after every shooting event, then Gun Juice would be a good lube and protectant during the period of storage prior to the next shooting event IMO. A light oil is the idea - not axle grease or STP oil treatment.
