Hornadies latest manual shows 37.0 under the 160.
I'm using 36.0 and getting 2288fps from a 20" barrel and getting excellent accuracy.
I'm also using 36.0 under the nosler 170 partition and getting super accuracy.
If I zero the 170s dead on at 100 the 160 ftx lands about 1.5" above it.
Just for giggles thinking of carrying both in the field. Figure on using the partition for drives through heavy brush where shots are often under 25yds.
Then sliding in the 160s for end of day sitting on a logging road where open shots can be an easy 200 yds.
