Id concur that careful cleaning of the rifles bore , with careful cleaning with solvent and patches and barrel prep,
like use of fine abrasive copper fouling removal before and recurring frequently (at about every 5 shots , during the initial barrel break-in, )
on a rather frequent repetitive basis, during the first few shots can provide noticeably better barrel life and in many cases improves accuracy
careful cleaning with copper/powder solvent , a jag of the proper matching bore size , and a patch soaked in moly spray, before you shoot and after about every 5 shots during the initial trip to sight in the rifle helps accuracy in many cases
