I wondered about a nicked seal, however I thought that might cause the groups to be vertical . My groups are : two maybe three shots close and then one a distance away, like an inch or two or more and this is in the 30 ft. basement ! I initially thought I was pulling the shots but it happens to cyclically for me to be doing it. I have a shot string from 2 weeks ago: 709.1, 723.0, 722.6, 712.1, 715.2, 714.2, 720.8, Error, 722.1, 711.5, 717.2. I should have an opportunity to shoot outdoors today and will save a group to post. Everything can be fixed its just a matter of time and money, maybe sanity too ! I love a sleeper but at some point you have to determine when to stop. I am looking for or at that point.
Here is a link to a photo of the groups I described above.http://s1107.photobucket.com/albums/h390/gymhock/?action=view¤t=IMG_2535.jpgAlso, I took a close look at the breech and it looks like the bore is not centered in the middle of the breech seal.I don't think I can get a picture of it but I measured the distance from the edge of the bore to the edge of the inner circumference of the breech seal bore and found about 10 thousandths difference between one side and the opposite side. Can that cause my poor groups ? Is this variance acceptable ?
