We were back at it on the range with the .50 caliber CVA Accura LR-X with the goal of getting a good load for our spring bear hunt in Oregon. We are using Pyrodex Select, Thor Lighting Bullets, Federal 209A Primers, Anarchy Outdoors Muzzle Brake, and Burris RT-25 Scope.

We latter tested with 70, 77, 84, 91, 98, & 105 grains by weight of Pyrodex Select and determined that 105 by weight was the best charge with this gun and powder combination. We were able to achieve a standard deviation of 79 (I think this number can be reduced with some fine-tuning) with an average muzzle velocity of 2,175fps and we shot a pretty decent group at 100 yards (this too I think can be reduced with a few adjustments). I think that this muzzleloader is almost ready for bear season!

Not bad but I'm curious. You loaded up charges from 77 gr to 105 and 105 you said was the best charge! How do you know for sure? Did you try 110 gr? That may be better still. Anyway that's the first thing that came to my mind.
