Yes!! Definitely needs to be cleaned since it is new. Probably more dirty now new then after 30 rounds ran through it. Like I said whatever solvent you are using to clean your barrel with run several wet patches through and let it soak overnight. The next day run another wet patch down it. Then put your bronze brush on and pour a little solvent it (don't dip brush in solvent you will only get your solvent dirty). I always pour solvent on everything. I have a little squeeze bottle I use. Then after your brush is wet run the brush through 20 times 10/10. Then run a clue wet patches through to clean out any crud. The uhn start dry patching it. I continue this process until clean. I also use some JB Bore Paste and Krill Oil before I use my Bore Tech solvent.
These are the patterns I get using Indian Creek chokes in both my guns. Top is a Mossberg 535 and an Indian Creek .665 constriction. The bottom is with a Mossberg 835 with an Indian Creek .675 constriction. Both with 3" Apex #9. Moved my red dot a couple clicks right on the top one and centered it up same with the bottom one to the left a couple clicks and it was dead center.
