Guns, Bows, Shooting Sports, and Hunting Rifling Twist VS Rotational Speed

[GHarman]

Has anyone else experienced the phenomenon with 5. 56/. 223 rounds of lighter weight (52, 55, etc) bullets climbing and/or erraticly flying in fast twist (1:7) barrels?

They will certainly blow up fast, especially if they have thin jackets. They will probably print at a different location on the target than a heavy bullet fired in the same rifle. I assume you are talking about an AR-15? GregH

OK I give. what I was believing is that the spin of the bullet was always relative to the distance traveled. My means of determining this was simply considering how many rotations a bullet would make utilizing a 1:12 rifling and travelling 1000 fps versus 4000fps-this lead me to belive that the bullet would still be spinning at 1 revolution per foot but the time to travel that one foot would increase as velocity decreased. Not trying to be a troll here, just an avid shooter and hunter. Thanks for getting me straigtened out on this.

Definitely not a Troll, Bud. Thats what we post for. Exchange information and a good hearted "dis-cussin'. I certainly dont have all the answers. Its just fun to take on a subject. I'll leave the physics to the Physicists. I just love to shoot rifles and build 'em. GregH

simply put, tighter twists are for heavier bullets.

LMAO after reading most of this thread, Bglidewell sumed it up with all that matters in one sentence. There's 20 minutes of life I want back.
