Teflon has a bad reaction during combustion. Try burning a Teflon coated pan sometime. Using T7 it makes the crud ring more pronounced. Using BH209, the fouling becomes almost gummy and can harden as it cools.

It provides ZERO benefit IN the bore vs any good synthetic oil without it. Even Mobil1 Auto oil would provide better internal protection. If you are going to use it IN the bore just make sure you swab it out very well before shooting and it probably wont be an issue.

I used common Brake Cleaner to remove it one day as a test and it worked great. be careful not to get it on your stock or plastics though. Just running a dry patch and snapping a primer/s is my usual pre fire routine. Now i use Montana products for short term storage and all those issues went away. Any good synthetic oil without Teflon will likely give you similar results.

Oddly there is a technique using the hated BoreButter that can reduce the crud ring too. I did it by accident using it for years in my old ThunderHawk. That gun can shoot at least 5 shots and gets almost no crud ring with T7. I didn't put 2 and 2 together until i read Sabotloaders BB technique and it all made sense then.

Try the Montana X Bore condition for at least three range sessions and see if you get good results. I THINK most have seen an improvement vs Remoil or other Teflon based products. I still use RemOil on many part but never in the bore anymore.

As far as JBs, 50-200 strokes seems to be the norm depending on your needs. I also use MX Copper Cream and the MX bore paste once in a while too. The Copper Cream is also good at removing sabot fouling although ive never had that issue in mine.

I now firmly believe a well polished bore solves or greatly helps a lot of fouling, loading and cleaning issues. Plus may improve performance too. My hand lapped Douglas barrel produces better fps than a JBed Savage barrel and they are very close in length...at least according to the archived reviews ive found. The loading difference "feel" is like night and day.
