I've had all 3 of those rounds in Bullberry single shots & they are superb! Used 2 of them in Africa with great success along with my Freedom Arms 475.
Keep meaning to ask, how many deer can you take in Texas now, it used to be 5 when I was stationed there.
Here's a few of my Montana white tails, along with one calf elk taken with one of my Bisley 45's & also a muley buck taken along time ago with an XP100 in 250 Savage.
