I ended up putting a Leupold VX3, 1.5-5x20, on my rifle. Took it to the range today. I tested the 300gr Ballistic tip with IMR4198. Initially, 41.0gr of 4198 gave me about 3” group. So I started at 42.0 and went up in 1gr increments up to 45.0. 42.0gr was terrible, 43.0gr was 1.18”, 44.0gr was 1.6”, and 45.0gr was terrible. I’m going to test 43.0gr again, and if it gives similar results, I will call it good.
