Re: Highest 30 Cal BC?

The Barnes bullets have high BC because they are all copper and are long bullets.
The 180 boattail BC is .552.
Some people have problems getting them to shoot. Usually between the XLC (blue coated) or the triple shock one of them will shoot well out of a clean barrel.
From what I have read and my own experience they tend to shoot better out of smoother barrels for ex. a custom barrel vs. a production barrel.

Re: Highest 30 Cal BC?

I shoot the Barnes bullets in my 416 Wby, the BC on the 400gr XLC isn't but .380-.400 I can tell you that much, it's no where near what they claim, all the others I've used except for the 168gr XLC were severely inflated too, FWIW.

Length has almost nothing to do with BC. The Barnes bullets have high advertised BC's because Barnes exaggerates them. Any of the plastic tipped bullets will stomp them when BC's are tested side-by-side weight for weight.

The 200gr Accubond has a high advertised BC (.588). I have had good luck with them as far as accuracy in my gun. I don't know if anyone else has had luck though.

Re: Highest 30 Cal BC?

I shoot the 200gr Accubonds I'm curious as to what the actual B.C. is? I would like to run my info through a ballistics program to determine bullet drop at different ranges but I'm afraid simply punching in the BC 588 will give me bad data! [img]images/icons/frown.gif[/img]

NS,

I did a downrange velocity test for a BC check here just a couple of months ago, .585 is what it proved to be. Just punch it in and you'll only be looking at MV to modify now, that, temp and BP... You should be good to go; worked perfectly with my program, Exbal, out to 600 yards in the 300 Ultra last fall.
