8 x 39 mm 338 x 39 mm
Does anyone have some info about these wildcats? I saw them listed in a die maker production list, but I don't know their shape.Are they based on the 7.62 x 39 mm necked up?

boom stickStarting off with the 6.5 Grendel case might be the best option since Hornady is producing it now. No forming brass but just necking up. I dubbed the 338-6.5 Grendel the 338 Thor. It also can be the 8.5 Grendel to make headstamp and barrel stamp easier. .338" = 8.58 MM
