[QUOTE="jmitchell135, post: 1008391, member: 76521"] I have been reading a lot on the topic too and I think you might be on to something. I understand the rifling to cut grooves or leave indentions or impressions, however you want to see it, in the bearing surface of the bullet as it goes down the barrel. Say for some reason the bullet goes into the chamber crooked and one side gets a groove started further forward than the other side, then the bullet would have more friction on that side and start a wobble sooner than if it was evened out. Now with more bearing surface you would have more to get an impression on. I would think it would have more effect on the flight of the bullet. Say causing more friction possibly even changing the BC of the bullet....? I also understand the direction of wind to have a slight vertical effect on the bullet so with that in mind, the more surface area that is "gripping" the more it would be effected. Think about wider tires. This is just my understanding as I have read and how it has been described to me from some pretty knowledgeable folks. I may have misinterpreted so don't burn me at the stake. [/QUOTE]
