The purpose of using synthetic oil, grease r any other synthetic is "WHAT' ? Chemistry 1o1.
One of you sez WHEEL BEARING GREASE, THATS GOOD, I CANT GO FURTHER THAN THAT, MAYBE HE JUST DOESNT KNOW or care. He should be
told who ever did the threads did a lousy job but he is cunning enough to use a heaver molecular grease so it works now.
The GERMANS have been using SYNTHETIC OIL SINCE WW11 in their engines and more. NOT USA.
Doesn't your shot gun deserve a good lube? The fine threads in your barrel, LOOK
I have a thin barrel ,the SMITH said, Im an expert, yes he is, but not using thin wall choke tubes. Looking down the barrel from receiver the threads are not deep enough
so the raised edge inside collects anything coming thru it. Sooner or later the threads will wear down cowboy shooting, its all its good for now
and soon the barrel will be cut 1 1/2 inches. BE CAREFUL.
