So far I have really been fortunate on this subject... with all the different inlines I have owned I have never stuck a breech plug (I am knowcking on wood right now), but, I do go at it in a different method... no grease and tightened snuggly - but not to tight...
It is my belief that you must stop blow-back at the face of the BP and the rear flange in the barrel. if you are able to get this done you need not worry about stuck plugs... I shoot either a 100 or 110 grains of T7 consistently with 209 ignition and it works for me. I just posted my method again in:

for those that might be interested in it... but again it works for me and others but your results might differ....
