303tom I can't even take a guess at most of your larger rounds LOL the .50 I get and the .308, 300, .338Lapua but that's it LOL.
You were right on every thing on mine besides the .303 its actually a 7-30 waters like Scotty said. Ill let the little mystery round stay that way for a bit longer......its normally referred to by its metric designation, and that load uses 88grn Berger flatbase vlds.....
.22 CB, .32acp, ***?, 9mm shot?, 9x19, .17hmr, 5.7,
5.56 crimp blank, plastic trainer?, Dummeh, 855,
7.62x39, turtle-turtle, .260, .308, .303, '06, 12ga, 10ga, coffee cup? 40mm grenade?
It's probably just me, but all I saw was a bunch of bullets lined up across the top of a tweed amp, and I'm wondering more about that!
