The CVA Staghorn was moved onto the front porch out in the elements in the day time and then at dark moved to the back room where wood is stored in the house. This back wood room is dry, but can get rather cold at night. I then with the Knight Rifle also moved it from the porch to the wood working building which prior to, I had dried out with a space heater and then tried not to track any snow into it. Although that building always feels cold to me.

Today, I took both rifles out and shot them. I started with the CVA Staghorn Magnum which has a RED DOT 1X scope on it. The new primer was put in the rifle and this time it fired perfect so it seemed although the shot hit a little higher then I thought it should have. I then swabbed between shots and shot off six more.



The Knight Disc has been moved from the porch to the wood working shop. I figured this rifle would act up if any of them did. I put a new Winchester 209 primer in it and shot. It hit actually just to the right of the main group. It fired fine. Why the change from the last time. The only things different were the powder and the fact that I used a space heater and dried the building out a little.


I fired a five shot group with the Knight Disc and was more then happy with the results. So the question is, was the humidity that much different with this test, or was the fact of drying out the shop the factor, or the powder. What ever it was, this time the rifles shot fine.

The CVA was never brought into the house other then the back wood room. The time before they were brought in to a warm room. So maybe the original thought of condensation was the thing that caused all of this.

After that I broke out some other rifles and tested some different powders. Then spent the rest of the afternoon cleaning rifles....
