That math just doesn't compute in my poor little brain. I'm just looking at pics, mind you, not throwing the calipers on the bullets but that Barns bullet looks a good bit wider in the front than the Lehigh.
You know I honestly do not know... I have no claim being a ballistic person... I just give the program the information they ask and it returns a number. The computed BC is still far below their posted BC for their 451-300 Expander. I was actually hoping it would compute higher.
I will not know the true facts until Grouse has time to shoot it through his Chrono's. But with it being hunting season that may be way down the road.
Barnes 300 Expander
Diameter .451
Weight 300
Length 1.036
S.D 0.211
B.C 0.207
I could add when I have the two bullets side by side the Lehigh appears to be the sleeker bullet more in the form of a real rifle bullet adding the tip will even make it more streamlined. But, then again I am biased as Lehigh Dave's bullet always appearance more designed as rifle bullets to me.
