one other thing i forgot to mention. You need to season that bore, much like a cast iron skillet. Get some T/C Bore Butter and lube up that barrell so you can get 'er seasoned. I'd do it soon if you can. Good luck and good shooting!
This works for so few that use sabot/bullets.
Actually a bad idea all-together. Keep your bore dry & use a good gun oil for storage purposes. This eliminates the chance you'll make a "seasoning' mistake & find your bore rusted a few weeks or months after applying the butter.
