[QUOTE="Mikecr, post: 1227457, member: 1521"] Jeff, what you saw was the result of moly use + your notion:"Clean when your accuracy starts going south". You have to manage moly use, which includes constant cleaning of it with JB compound, to prevent build up. Once it's built up to the point of bore constriction, there is no recovery. Gene, moly in itself reduces pressure and MV. So not only does the load not need to be reduced, it will likely need to be increased. Also, there is no solvent that removes moly. Only abrasives work on it. If you clean a bore subjected to moly normally, it will die(accuracy-wise) just like Jeff's. Honestly, I'm surprised that moly is still in use at all. What moly can do, as described by Jeff, is show us the ultimate killer of a bore: Constriction. We have WS2, which reduces copper fouling as well, does not change MV, and cleans out just the same as carbon(it doesn't bond to itself like moly). But moly can and has been managed well enough to actually extend barrel life(through charge cooling). It just takes a plan. While the advantage sought with moly is extending shot strings before copper fouling out, and it works, that never meant reduced cleaning requirements. [/QUOTE]
