I'm sure somebody has made a bigger, meaner rifle round than the British .303. But I ain't seen it yet... and if I ever do, I don't wanna shoot it. I can already set off my own personal earthquake.
I'm used to popping shotguns, pistols and .22 LR's. The first time I lowered the hammer on my Lee Enfield I thought I'd been hit by lightning. I held my box target down with a bowling ball sized rock, which exploded on the first shot like a grenade and was the size of a baseball afterward. No foolin'. Gifted with a firm grasp of the obvious, I thought "Yep. I got me a big frickin' gun here. Now all I need is 5 rounds and tickets to an N'Sync concert."
There will never be concentration camps in America.
We'll call them something else.
