I would only suggest that you shoot it awhile before you get to concerned about groups... I really think it is important to break in a new barrel, @ least 100 rounds then start working for your desired goal. The other + about breaking the gun in you get to learn about the gun at the same time...
What are the pre-treated patches??? I hoping that they are not the T17 or even the the Knight pretreated patches...
I use windex patches prepared at home and used at the range... lots of people also use cayugad's 50/50 mix of windshield washer & alcohol...
I make mine from regular windex with ammonia - I prefer the metal cleaning of the ammonia to the other windex with vinegar..
