The 150/50.0 Varget load did great in my Turks, but not so well in my K98k. My K98k shoots better with 195/45.0 IMR4064. (Maybe I need more K98ks;) )
The good thing is that the 170/50.0 H4350 load and the 150/50.0 Varget load shoot to just about the same POI.
Great shooting on your part.
Here's my Turk target. From a cold bore, the first two shots high and to the right, the other eight pretty much right in the center.
