After spending a lot of time with my Knight 52cal and the new .458 Lehigh bullets i decided to try those same bullets out in one of my 50cal Knight Vision's.
The first bullet out of the gate was one of my new favorites. The .458 220grn bullet. This bullet was made for the 52cal, and after today it's going to be also great in the 50cals. I decided to start with 120grns of BH209 and the orange .458/50 MMP sabot.
I will note this bullet really opened up with 130grns of BH209. It really liked 120grns.
The next bullet up was the .458 300grn Lehigh. It shot pretty good as well. I actually think it would shoot better with .452 harvester sabot.
