For Christmas I got a great present from myself, a Rock River AR 15. This one:

In anticipation of a new AWB, I have also been stocking up on ammo. I came across a pretty good deal on Hornady TAP, and got several boxes including some 75 Grain ammo. I have been doing some additional reading to learn more about my weapon and other options for it, and came across this:

The guy seems to know his stuff, but claims that you need a barrel with a 1:7 twist to shoot 75gr ammo. My rifle (and damn near all new RRAs) come with a 1:9 twist. The last thing that I want to do is wear out my barrel early, and I damn sure don't want to throw rounds down range that are tumbling.
Do any of you have any experience with shooting 75gr with a 1:9 tube? Am I worried for nothing? Should I have bought a rifle with a 1:7 twist? Does it even matter?
Thanks
