I load 150gr Winbullets over 35gr of 3031 in my marlin. It's .5gr under the listed max in the load data I have. It chonos about 2500fps and I get 1.5" 10 shot groups at 100 yards with it. I too use the lee factory crimp, it works great. This load worked so well I never tried the 170's. I even took a deer this year at 150 yards with it, one shot DRT.

I am interested in getting some of the Leverevolution bullets to try when they become available for reloaders.

Good luck on your quest for loads.
