One more try at this today with a little more magnification. I took the Nightforce 2.5-10 off and replaced with a 16X super chicken that I use for load development and that kind of stuff.
Load was 25gr of Varget with the 77gr SMK in Winchester brass. A warm load but fairly accurate.
The two shots that went high on the left target were the first two of the day, from a clean barrel. Probably should have fouled it before trying for a tiny group.
