Re: Check these out!!!
I believe alot of the data is coming from teh manufacturers of the bullet forming dies and is taken off bullets actually made with the dies.
I do not know what method is used to mearure the B.C.
I can say that I have tested several of his bullets over 500 yards and they have all met or exceeded the B.C. projections listed for the bullets.
I test by measuring bullet from with a 100 yard zero and then firing for drop at 500 yards. This may not be quite as accurate as multi point velocity readings but it is close enough for what we are doing here. ITs more accurate then 90% of all the B.C. listings by the major bullet makers in the manuals, save perhaps Sierra.
