I don't clean the rifle during the hunting season because of first round being different. But after Hunting season it gets a real real good cleaning. ( NO I was not talking about the first round pop )
Hunting, I shoot a lot less, than if I was going to Range each week or shooting competition. If I am to shoot competition then yes it gets cleaned after each time.
A small part of this depends upon which powder you use, since some shoot cleaner than others. We were using AA#2 with 45 ACP suppressed full auto and it was dirty WST is very clean. The results were different. Vhitavouri is usually cleaner, but pricey.
