I took your advice and just used two of the .008" patches together. I've shot the most consistent this afternoon as I have ever shot with this rifle. I had 8 shots in a 2 1\2" circle at 50 yds. This was off sand bags.
This may not be tight by some standards. But I was tickled to death just to feel as though I was making progress with the help of all you guys.
Just to recap, I'm using Hornady .440 round ball,.016" patch,(2) .008 patches together, with 45grs Goex 3f powder.I am swabbing the barrel between each shot.
I want to try some different patch material but I think .015" thick material will be my best bet.
I surely appreciate each and every one that has put up with my many questions and offered advice along the way.
Thanks
Donald
