I used to rush past crown cleaning until a customer complained about groups
A dirty crown destroys accuracy, so I take my time with it now.

Back when I worked at a gun shop in Tucson, we saw a lot of neglected crowns. A pick can work, but you gotta be real careful not to scratch the metal. I use a brass pick from my reloading kit for soft carbon buildup. Honestly, if it's really stuck, a soaked patch left overnight does wonders. Tbh, rushing crown cleaning is just asking for flyers on your target. Once saw a guy's group open up 3 inches at 100 yards from a dirty crown.

My buddy Steve in Kentucky had a nice .308 that started throwing shots all over the place. He was cleaning the bore but just giving the crown a quick wipe. After a real deep clean with a brass pick on the crown, his groups at the range tightened right back up to under an inch. It was just packed with carbon he couldn't see. Makes you wonder how many accuracy problems start right there at the muzzle.
