Highest 30 Cal BC?

[Guest]

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.

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.

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!

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.

 

[NorthernSniper]

Hey Brent! Thanks This is really going to help. Wow I thought Nosler would really B.S. it up 585 is pretty close to what they claim.Thanks Again!

Has anyone tried the 225 AB for 338?

Do accubonds come in any other weights for the 338?

 

[Jon A]

I think Nosler's listed BC is pretty darn close as well but I don't have all the fancy tools Brent does.

My dad had good success on deer and elk with the 225 338 AccuBond in the 338 RUM last year. No serious long range testing though. I did do one penetration test and it penetrated the same as a 225 Northfork.

John,

The 225 Accubond is amoung the very most accurate in his 338 WSM.


Jon,

Two good Oehler chronos work well, nothin real special (cost of a factory rifle), and I'll bet that's what Nosler uses too... who the hell knows "what" Barnes is playing with over at their place though!

has anyone done any tests on the 240smk? I've heard the BC is higher than the stated .711

What brand bullet(s) have the highest BC in 30 caliber with bullet weights from 175-210 grains?
I figured you guys would know this info as well as anyone. My 30 cal rig pushes a 180 grain bullet @ 2785 fps.
Thanks

I am aware this post is fairly old, with that said I shoot thousands of rounds every couple months. I'm disabled an have a lot of time on my hands, my main hobby is shooting precision with the .308 and the .223, with that said let me get to your question which nobody on this page has answered correctly! As I said the post is old but since then a .308 round had been developed that will keep up with the .300 Win Mag, The correct answer is the Alco 30 caliber Rebated Bullet, The 168 grain .308 round has a BC rating of .618 which makes the trajectory very flat shooting out to a mile And I know they have the bullet in weights of 175gr and in the 200 gr range, The bullet is called "Alco rebated" They provide phone numbers for purchase, I attempted to purchase on line but Washington state is not supported for that. They carry two types a "Top Match" and "Ultra Match" they are not cheap $79-$93 a hundred

You've got that exactly backwards, they have lower BC's compared to lead core bullets of the same weight because of the density of copper being so much lower than lead.

Because they are so much longer than lead core bullets of similar weights they also typically require a faster twist rate to stabilize the bullet which is why when you get into the heavy for caliber bullets people often have a difficult time getting them to shoot well.

Welcome to LRH and enjoy!

As you noted, this is an old thread and there's a few guys here that had plenty of time to test the Alco bullet, i.e. ... >>> http://www.longrangehunting.com/forums/f19/alco-308-230-grain-bullets-179870/

In comparison with 230 Alco RBT with a G1 of .680-.685, the 230 Berger hybrid target (30430) has a G1 of .717 and you can get them for $52/100 (http://bullets.com/products/-30-Cal-308-230-Grain-Match-Hybrid-Target-Bullets-Case-of-100/BL10124)
