I just bought a T/C Omega. It's a 50 caliber with a blued barrel. I but a BSA Huntsman 3x9x44 scope on it. Although I have not shot it yet, I plan on using 777 pellets with a Precision Rifle's Dead Center 260 gr. bullet. My question for all you experienced shooters out there - Do you use an actual barrel cleaner when cleaning, or do you simply use water? Also, what do you suggest I buy to apply to the bore when putting the gun away for an extended period of time? Is there anything I should put on the outside of the barrel? Thanks for the help.
