I clean out or do not clean out the load depending on the hunting conditions I am hunting in. But I never go more than two days at a time without cleaning the rifle. And normally I will clean every day. With an inline it is easy. Just take out the breechplug and clean the rifle without shooting it.
The more moisture or humidity-the more often you need to clean. Moisture is the enemy here. I normally put my rifle in the back of the truck a day or two before the opener. Then I load my rifle under the hunting conditions, and I leave my rifle outside all the time. I never put my rifle in the hot cab of the truck, or the house. If you do that then you will get moisture with the change in temperature. Tom.
