The "mechanical action" is not required with this product. I am a BR shooter and when I start a relay the tube is down to clean bare metal every time, and the bore scope does not lie--ever. Until this product came out and while picking up my 375 ENABELR few weeks we ago discussed it at length I used Iosso and a few other products and with this method there is NO residue from the bore paste to clean out which can be a PITA! I have 15 Speedy rifles both competition and sporters so far and all of them "dots" as Speedy likes to say if the bore is maintained.
