[QUOTE="Mikecr, post: 31280, member: 1521"] That was the way I thought as well. RPMs. I believe that if you explore it further though, you'll find that its revolutions per distance. Meaning -it don't matter how fast its going, or what the RPMs are. If a bullet requires 1 turn every 8", then thats what you have to give it. Revolutions per distance is set purely in twist(1:8"). No amount of velocity or resulting rpms change that. Only twist rate. Difficult for me to grasp, but I'm jumpin the fence anyway. Sorry [img]images/icons/rolleyes.gif[/img] [/QUOTE]
