Tried shooting at the lower nodes td. Seems like the gun kept throwing one which I'm assuming is due to the primer/burn rate. I shot a couple .8 groups but not acceptable to me. Additionally, something interesting is I experienced some kind of pressure signs through the entire powder spectrum. Just was never going to work in this rifle. I bought 1000 215s for $325 shipped and sucked it up to my distain.... Guess I'll shoot that 350 this year.
