J B bore cleaner

Tried JB bore cleaner on a Colt saa that leads real bad in the forcing cone with only a few shots. Did not do good for me, I had to use a brass cleaning rod, If I had only used the JB cleaner it would have taken at least 10-12 hours constant cleaning. Maybe I order the wrong stuff, jar says J B non-embedding bore cleaner compound. Got it on Amazon. Any comments please.

When my 29's were new I could pull wires of lead about 9 inches long out of the 10 5/8 tubes. I made my own forcing cone polisher and the jag for my cleaning rod and patches. I did polish the bores and chambers with the bore paste. After a few hundred rounds they quit leading for the most part. I mostly run my own hard cast bullets sized to .431 with 50/50 Alox/beeswax on top of a full load of BlueDot.
Added Big difference in polishing an existing forcing cone (easy) and cutting one correctly. Have you inquired with Colt to see if they will fix it? Can you post a good pic of the forcing cone area?
Your bullets are most likely too small or improperly lubed if leading.
In a stripped and clean bore, a tight JB embedded patch is difficult to push thru, sometimes requiring a few hits with the palm of my hand. After 6 or so passes with JB embedded patches, with traditional cleaning in between, the JB patches push thru much easier.
I dont want to be rude. BUT YOU need to at least take it to a gunsmith that knows about revolver forcing cone At this point your description of machine marks /grooves /polishing /reaming are so vague& confusing we dont know what the problem is except it Leads the bore and does not shoot good groups.
