The first one was a fouling shot and I have no idea where it went because I shot at the small target on the left side of the power but didn't hit the paper. I felt like I pulled it when I shot though, then the next two were the two that went right that you see on the paper. After seeing those I made a scope adjustment and shot the 3 shot group you see where it was one big hole right to the left of the bullseye. Realizing I'd gone to far, I moved it a click back, and shot at a new target that I didn't take a picture of, but it hit where I wanted it to in the center then.

As for the gun, I should have mentioned that above. It's a Marlin MLS-50 that is supposedly by for T/C for Marlin. It is not exact, but very similar to the Black Diamond rifles. I'm shooting 100 grains of Pyrodex in pellet form, and a 300 Grain Speer Deep Curl in a Harvester Crush Ribbed Sabot. I'm also using CCI Magnum #11 caps to light it all off.

I've also used Pyrodex in loose powder form and it shoots to the exact same POI and the groups are nearly identical in size. I normally shoot pellets in the field and powder on the range to save money, but this time I shot the pellets mostly since that's what I'd be hunting with, although I took a shot with the powder and it hit the same POI as usual as the pellets.

One thought brought up on another forum is could temperature change do this? It was in July when I last shot it and I don't know what the temperature was, but I'd guess 85-95 degree's. It's been a lot colder since then, but it was fairly warm yesterday. While I don't know what the temperature was while I was shooting it, I'd guess 65 degrees or maybe 70 max. I had a jacket on while shooting and while I could have survived without it, it was the perfect day for a light jacket.

Do you all think that could affect where it shoots?

Not anywhere near what you're getting.

Well I wouldn't put much faith in a $30 scope. Now if you don't want to spend a bunch of money on a scope, you can pick up a Nikon Prostaff for <$150 which would serve you well. And a straight 4X would be even less and is all you need.

That's kind of how I feel, and I've actually got a Nikon Monarch I could slap on there, but I just hate to change it out if it's not bad. It's just sentimental reasons I guess. That's why I'm wondering if this is the sign of a bad scope.

If a scope going bad can act like this, or could be bad I will probably change it out, and I may do that anyway.
