Hi guys and gals, I had been shooting my muzzle loader earlier this week and again today. I wasn't able to get out last year so I hadn't shoot it sense 2009. The gun is a gray laminate wood stock and stainless barrel 50 cal. TC Omega with a Bushnell 1.5 to 4.5 power shotgun/ muzzle loader scope. I shot it Wed off a bench with the gun in a "lead-sled rest and my shots were all over the place. So I figured maybe the powder was too old. I went and bought new powder and primers and finally got the chance to shoot it again today. I am shooting two 50 grain 777 pellets for a total of 100 grains of powder with a 275 grain Maxi-Ball. I have not had any problems with this combo before. Well today I had the same problem my shoots were going everywhere. I would make a small adjustment and it would be on the opposite side of the target. Well I had another of the same scope still in the box so I changed scopes and still have the problem. I took the scope off and tried irons and still shots all over. I am running a brush and a wet patch followed by 2 dry patches down the barrel after ever 2 shots. The barrel is bright shiny stainless with good clean lands and groves. Over the two days I put more than 50 rounds through it. I was shooting at a slow pace and especially today the barrel didn't really warm up much at all. I was shooting at 50 yards, I would get a couple shots within a couple inches of each other then the next would be a foot away. I don't get it, any suggestions? Is it not stabilizing the bullets or something? I am reasonably sure this is the same bullet weight I have used in years past. I know the powder is the same charge and brand. Thanks for any help.
