Home Forums Hunting & Shooting Long Range Hunting Accuracy of Nosler Accubond (not Long Range) Ballistic coefficient?

Bob, you had a lot of "assume`s' in thoese shots!
Nice group tho...
The Hornaday calculator...a couple of years ago I took my 8x57 Rem classic to 600 using numbers I got from it. I was shooting 170grn SST`s. I believe it suggested 17 Mins. of come-up`s. Set a water jug, and hit it first shot. Actually had the shot on camera, and could watch the bullet go down range.
Some time it works some time not.

CG: Yeah that was my point....I shot that yesterday thinking about this thread.

Lots of room for error.

I personally think that the BC of a bullet is a bit variable beyond even the G1 being velocity dependent. There is the issue of twist rate being enough to stabilize for accuracy but not enough to get the max possible BC, there is the rifling style of the barrel and the condition of the barrel that are changing the shape and surface finish of the bullet, and there are lot to lot variations in bullets. None of this will show at 400 yards, but it can be seen at 1000.

That said, using Litz BC numbers for Bergers and velocity from a Magnetospeed, I've been within .1 mils of the data Shooter gives me out to 1100 for the last three bullets I worked up. Which is handy, but it's usually no big deal if you have to tweak the program to get things aligned at range.

Use this to test the scope tracking..Could be a simple input into the "Elevation Correction Factor" in your program will put you back on target..
