Re: Heavy Bullets!

The 177's run with a .638 bc. I run them at 3680fps. Rifle is a 30-338 Lap Imp. At this velocity the 1-10 twist is fine. Much slower and a 9 twist may be required. I have not tried them slower.

    Im thinkin that you need a monometal bullet just to handle the RPM's! Thats a fast .30 cal!

    Thank you for this post cwinner. I knew you had done some real world testing too, and your results resemble mine. I stated before some might be suprised just how much difference it makes and should see it for yourself . Even at distances shorter than 1000 the high BC heavies have their place. That is if you believe wind is our biggest hurdle.

    Nice test and good post.
