So the conditions were horrible but I had an itch so I went ahead and shot some of my test loads for IMR 8208 XBR powder, New Lapua brass, 175 smk's seated to 2.222" (ogive). I only had a little bit of brass left for loads so I used a range of 40-42 grains in .5 grain increments. Attached is a picture. It seems I should test some higher powder charges as I have no pressure signs. I think the middle node is at 40.5 grains. But it is hard to tell seeing I only shot 5 groups. Anyone know why the image is upside down??? I noticed on another post another image of mine was sideways? What gives, they aren't that way on my computer.
