Nice buck!I hunt muzzle load too, but in Washington State. Knock down, expansionand penetration are the key area's here. I have used a 360 grain Keith Nosed Sabot from Precision rifle for 10 years. I have taken many deer and a few Elk with that load. I use 110 grains of 777. They do not get up. Here is the website. Check out their cleaner too. Unbelievable. Hardly any smell, don't need to scrub your rifle down with soap and water. Best I've ever used.
