Stan, except on two specific occasions (complete DOG barrels: one 6mm & one .30 Cal.), I have used the same stuff/method successfully (sometimes the rifles win despite my obsession with losing!) - by successfully, I mean that upon bore-scope inspection, there is neither detremental carbon nor copper fouling; there may be very isolated and SMALL (I'd guess less than 0.062" long) areas of copper "wash"; a transparent film, as opposed to a visably built-up smear.

Here's what I use/do: I begin with GM TOP ENGINE CLEANER, to which I add 1/5th part MARVEL MYSTERY OIL (the latter just to provide a little lubicant). Having shot an ENTIRE Yardage aggregate (whether bare or coated bullets were used), I run three or four patches, wetted with the TEC/MMO concoction, through the barrel to remove any residue and hoepfully, begin loosening up whatever carbon may be present.

Next, I use either RemClean, ORIGINAL JB, or more recently, KG2 bore restorer (the latter was recommended to me by Casey , of PacNor rifle barrels); this stuff is applied to a TIGHT fitting patch, wrapped aroung a PARKER-HALE type jag, then the patch is "worked" through the barrel several passes, with particular attention (back/forth strokes) given to both the muzzle and throat areas. THis step is repeated once.

Next, I run three or four patches of the TEC/MMO thorugh the barrel to remove the "bore cleaner", followed by two dry patches and a single patch with a couple of drops of MT Extreme Gun Oil. Then it's time to shoot another yardage! ;)

I repeat this following the two hundred and the rig is ready for the next tournament.

My experience has been that a barrel which will not SHOOT using this cleaning proceedure, paprticularlly a thrity Cal., is probably not worth having on the action. I have enjoyed exceptional barrel life (rarely recrown - usually NEVER) and the bore scope has proven that my barrels are CLEAN.

Since the "fad" began, I have shot moly-coated bullet almost exclusively - frequently this last season, I got lazy and did not clean between yardages . . and usually ended the two hundred with my best target of the day at that yardage. Upon completing my final [200 Yd.] record match,  I always "empty the block"  by shooting a group on the sighter . . . to my utter dismay, even on days when my score shooting looked as though a blind pig had been pulling the trigger, those last four to six shots registered a nifty 0.5" or smaller group! If only someone would invent a pressure-release valve which fit in the ear! ;)

Following this abuse, I simply clean as usual . . and upon returning home, bore scope for crud - it's never been there . . . HMMmmmmm . . . . Since beginning this proceedure, I have consistently enjoyed exceptional barrel life combined with trouble-free performance.

Keep 'em ON the X! R.G.
