Ballistic Tips Work Better With Heavier Bullets

Ballistic Tips (BT's) were designed by Nosler for violent expansion / explosion and medium penetration on light skin type animals like deer.

For most calibers shooting BT's, you're better off using heavier projectiles with bigger Sectional Density's (SD's) than you would normally use for a regularly constructed bullet.

Why?

1. Heavier bullets for caliber are better in a BT because they tone down the violent expansion a bit and still have enough weight leftover for a complete pass-through.

2. The shock-value with the heavier BT will still be more than lighter standard bullets and you get more energy on target.

3. Short range shots also suit the larger round with a higher SD versus standard light weight bullets with less mass.

4. Raking quartering-away shots need a heavier round for adequate penetration.

5. A larger BT'd bullet is more forgiving if you shoot into the shoulder.

Example:

.270 BT's benefit from 150-gr. versus 130-gr.
30-06 BT's perform well with 180-gr. versus 150-gr.

Caution:

Standard bullets generally perform better on deer in lighter to mid-weight sizes.

Ballistic Tipped rounds are the exception to the rule as outlined in the opening post. Reported problems of a BT blowing up too quickly are generally associated with too light of a bullet.

P.S. I like a bullet to perform two things in my 30-06:

1. Violent expansion / shock.
2. Plenty of penetration for a pass-through.

The two best rounds I am aware of, are....for:

* Light skinned / boned deer: 180-gr. Ballistic Tip from Nosler
* Heavy skinned / boned elk: 180-gr. Partition from Nosler

For deer, I like the 165 grain .30 cal ballistic tip from Nosler. Good energy and good expansion. They work very well. 150 grain I think is the norm for the 7mm calibers.

The .323 and larger Ballistic Tips have a much thicker jacket than the smaller calibers. They don't expand quite as violently.
With the exception of the bonded core. The Accubonds are of a very similar construction. Only slightly heavier jacket at the bearing surface. In all calibers.
They are calling this controlled expansion. With a great retained weight.
I would guess. We will not be seeing the Ballistic Tips much longer in calibers larger than .308. They get the same BC and SD out of the Accubonds, with better performance. Unless of course there are enough small game hunters that like to use their 338 RUM to 460 Wea for Antelope and Coyote. Maybe a Blacktail or two.

I hate Nosler Accubond. I tested them like crazy and they just don't perform that great. They certainly don't deserve all the hype they get, when it comes to weight retention, wow do they fall short. In factory ammo, the 270 Winchester and 7mm Remington Magnum are greatly underloaded, probably so they can sell more WSM's.

That is interesting about your disappointment with the Accubonds.

The trend in bullet design seems to be headed toward the bonded core design. Speer was way ahead of their time with the Hot Core, TBBC and Grand Slam.

As for Nosler.
I have used the Ballistic Tips and the Accubonds. The Accubonds are far better for holding together on game.
Even the universally accepted Partition is not 100% reliable and the Accubonds are said to be comparable in performance. 60% retained weight.

From where does this disappointment stem. As compared to the Ballistic Tips where you are lucky if you have the better part of the jacket in tact.
The Accubonds are far superior in weight retention. Which in turn cuts a longer wound channel, etc.. etc.. etc..

The one other bullet that I feel doesn't get enough press is Hornady's Interbond. A claimed 90+% retained weight. I couldn't make a claim, as such, to qualify such a statement but, I do know that they do not come apart. I shot 3 weights in 2 calibers. Not only were they accurate through my rifles but, They mushroomed perfectly. I can't imagine not being able to get pass throughs. With the amount of weight retention.

For streamlined Spitzer Boattails with high BC's. The Ballistic Tip, Accubond and Interbond all have their uses and all perform a bit different. I would say that the one that performs to your particular need. Is the one that you use.

I saw accubonds recovered from deer and antelope last year and they have great weight retention,every bit as good as a partition,try testing them on a game animal before you give them a bad report.I saw a deer take several ballistic tips at 100 yards last year and they only penetrated about 4 inches before the came apart....worthless.I read a great report on all the main stream bullets on the market in a hunting magazine yesterday and they rated the ballistics for poor penetration and the accubonds and partitions for great penetration.The accubond does exactly what they brag about,great accuracy and outstanding penetration,I base my opinion by what I have seen in the field not what they do on a stump or other backstop.

Swift Scirocco are way better.

PS: NONYA I'd rather take something into the field that is reliable and something where I actually liked the test results rather than something where I did not like them.

You seem comfortable basing your hunting choices on "testing" and "data" aquired from hunting shows,I wont recommend anything to another hunter unless I have seen it perform in the field,thats just me.Im sure there are many bullets on the market that perform as well as the Nosler partitions and accubonds,maybe even better but those two I have used and seen them perform on game animals,thats why i recommend them,they have never failed me.

My understanding with the Scirocco's is, the copper jacket is softer than most. Which can leave deposits in the barrel. The very reason I don't shoot Barnes.

Most bullets leave copper in the barrel. The newer the barrel, the faster it accumulates. There's a very wonderful solvent out there called Hoppe's Bench Rest, it very nicely removes the copper fouling.

NONYA: I like your new name. It is very fitting.
