[QUOTE="Lefty7mmstw, post: 1133114, member: 48043"] I'm locked down to just over 2.5 miles per minute in my new Camaro ss. She's bone stock 'till the warranty's off, and they lock them down to 155 mph... After that, the car's going to get some serious upgrades if I'm not bored with it yet... As to 1 mile per second bullet speeds, we are limited by the gas velocity with current propellents. You need very light for caliber and heavy powder charges to get anywhere near 4,500 fps...The 223wssm and 220 swift need powder charges as heavy or heavier than the bullet even to do that... I have gone over 4,000 fps with a 7 rum and 120 grain bullets with a book load, and that is about as fast as you are getting a hunting weight bullet to go in any cartridge. [/QUOTE]
