The coated paper barrel portion and/or ejection plunger may be manufactured to as to exhibit a static Relative Sliding Resistance Coefficient (CSR) no greater than 0.250 and/or a kinetic CSR no greater than 0.210, for purposes of smooth manufacturing. In combination or alternatively, the coated paper barrel portion and/or ejection plunger may be manufactured to as to exhibit a static Gripping Slip Resistance Coefficient (CGSR) no less than 0.190 and/or a kinetic CGSR no less than 0.170, for purposes of consumer satisfaction.
