If that is the only stuff you can find, I would say get it and try it. Also you don't mention type of rifle you are shooting. Those heavier bullets are designed to shoot best out of an A/R, with the faster twists, commonly used in the A/R platform. I know for a fact that my bolt gun, with a 1 in 12 twist, will not accurately shoot these rounds. Also, what is the intended use for this combination?

1:9 to stabilize 69 gr bullets.

What headstamp does the brass have? RORG by chance?

Bullet weight isn't what you care about for a twist rate. Bullet LENGTH is. It's all about RPM.

Look up the length and run the calc, give you a nice idea
