I'm not so sure that was a particularly fair test for grease. The jewelling wear is a result of the barrel block being ever so slightly too large for the frame recess. If your 725 had more physical interfence than your 101 then it was going to wear more than the 101 no matter what lubricant was put in there.I found mine did that much quicker when using grease instead of oil. It took 32 years and 50,000+ rounds to show half that much wear on the jewelling of my 101 using oil and only a few hundred rounds using grease on my 725. I no longer use grease. I went back to oil. RemOil to be specific. I like that stuff best of all. Been using it as long as I can remember.
