Guys.. I could not get the gun to group at all today...I'm talkin' no consistency anywhere with any bullet. Last year I hunted with 2t7 pellets and a 265gr fusion. The load shot exceptionaly well 1" or so as did the shockwaves I had used before. I have one sneaking hunch.... The powder is not new...left over last year stuff and the primers are a bunch that I have had jacketed since last season also. I store my stuff reasonably well and didn't think it would be comprimised. The reason I questioned the powder was because everthing shot low...like 3" low consistently. I even shot a 3 pellet load under a lighter (250 vs 265) shockwave. Still low. The heavier charge didn't really behave any differently other than really crudding up the gun. So much in fact that I ripped the threaded insert out of my ram rod when I was swabbing the gun. It was probably for the better though..it made me stop shooting for the day!!
