I also had a 6" Mdl. 16-4, but in a moment of stupidity sold it about 4-5 years ago. It was really a tack driver. I also used the 85 gr. XTP, but with a charge of 2400 which was slightly more accurate in my gun than my H110 load, which my Contender preferred. The Contender is gone, too.
These days I use a 7 1/2" FA mdl. 97 .32. It's not for sale. I've learned my lesson.
