No, I think I'm still learning the ropes. SO far, I am leaning to a 348 gr Cabela's "Dead Center" sabot with 100 grains of Pyrodex. I'll try again this weekend, and mybe go up to 130 gr of powder with the same bullet and try some loads with 340 gr Powerbelt bullets, too. I'm runnin out of time.... I head to New Mexico on November 8.
