Went out for a couple hours this morning for deer, but none were at my area, so I drove up to the range and set up and shot at 75 yards. The first shot slightly left and centered up and down, second shot low and to the right. This continued for another 4 shots. I found a couple patches and one side was shredded. I thought, rough barrel? even during cleaning the barrel never showed me any rough spots. The I thought, Maybe patch just not tight enough.
So I switched to a .018 Ox-Yoke prelubed pillow ticking. That did the trick and the 75 yard group tightened right up. 8 shots 3.5" group. I think this load is better and shots #6,7 & 8 were shot without cleaning. I usually clean after the 2nd shot.

There is one shot off to the left in the liver area. that was shot off hand at 85 yards. I was on the wrong side of the tree and not steady as I should be.
