Hornady A Max issue

[CINDERS]

You may have heard the A Max has had some issues with changing BC of the bullet in flight due to the friction of the air over the ballistic tip actually melting it. After exhaustive tests Hornady discovered this fact using Doppler radar they now have resolved the problem and offer the new ELD bullet but this will take a long time to reach our shores in Australia.
So I thought share with you some of the dynamics involved to give you an idea of what a projectile goes through whilst in flight apart from the obvious.

From Townsend Whelens book Vol II Page 75;
The 30/06 bullets starts off at 2,700fps and encounters a gentle breeze of 1,841 MPH (on the nose my italics) which reduces its velocity to 2,460fps at 100yds. The 220 Swift at 4,140fps encounters a breeze of 2,283 MPH on the nose.........
So imagine the heat from the friction it is some thing I never really considered but the figures show that there are lots of dynamics affecting a bullets flight (Mann).

Just finished a book on John Nosler "Going Ballistic" I thoroughly recommend this book a rather great insight into his life and efforts to build a reliable expansion bullet.
Even if it did take 22 years of solid work on it alone for his dream to really flourish I enjoyed it very much a bit milder than Elmer Keiths "Hell I was There" another fantastic read.
