I understand that having a longer barrel allows more of the powder to burn and accelerate the bullet, to a point. So the barrel is an acceleration chamber.
I am thinking of purchasing a SW .500 mag and have been grappling with barrel length. After handling the guns, the 7.5 seemed the most well balanced and least cumbersome in my hand. But am I losing power?
The guy at the gun store says no. "the barrel is long enough to stabilize the bullet and these flat bullets roll when they exceed the speed of sound so this is fine." and he said (paraphrase) "So basically you have a slow heavy bullet that will attain its max speed, and a pointed or rifle type bullet, like a .460 will really hurt with a few inches off the barrel but not a 440 grain .500" Is he correct? Thanks for help!
