I've got a Tasco scope on my both my muzzleloader and my rifle. I sighted both in a few months ago...taking many shots with each. I had not shot them since.

I missed two does during muzzle loader. I came out and checked my gun and I was shooting about 4 inches to the right. This morning I shot at a spike with my rifle and missed it. I came out and it was shooting about 3 inches to the right also!!

Anyone ever heard of anything like this? The guns lay on their sides in the closet. Are these just cheap scopes or could there be another reason? Thanks
