First of all, I am not trying to start a bullet war just wanting to point out some noticeable changes to the Nosler Ballistic Tip and some of my observations.

When the Nosler Ballistic tip came out and up until recent times they were known as a quick killer, but many complained they were "soft" and came apart too easily. I never had a problem with these characteristics but put them on the same level as the Sierra bullets being accurate, quick kilers but soft. I preferred the Hornady Innerlock bullets due to performance on game and that they displayed a bullet with a "tougher" construction. In the past few years it seems Nosler has thickened the cups on several models(usually using the same blank to draw cups for different bullets in the same caliber). This produced "tough" bullets like the ever more popular 120gr 7mm BT. These bullets seem to perform better than they should. Recently, I have no clue when, it seems Nosler changed the cup and core shape of the BT and thickened the cup and base which in my opinion is a good thing. I cut a few Accubonds and some 308 cal BT to see the construction recently. I noticed that most of the BT I cut shared the same internal shape as the Accubond. My pictures did not turn out well but this picture was posted on another site so I stole it.

Here is a picture of some Nosler bullets with the older internal shape I was refering to.

You can see in this picture some of what I have been witnessing with my own bullet dissections. The 7mm 120gr Bt has a thick cup and traditional style core. They perform very well on game and are known as a tough bullet. The 7mm 150gr BT has the old style cup and core construction. The Accubond and newer BT has a noticeable different shape. The .308 180gr BT is known to be a tough bullet and has a very good reputation.

I have always been a big fan of 165gr bullets out of my 30-06 rifles. Recently I have been looking at the new 168gr BT and after cutting one apart and seeing it shares the same design characteristics as the well respected 180gr BT I am excited. I hope I can find a load that shoots as well as the 165gr BT and 165gr Accubond and I am expecting it to perform very well. Enough of my babbling, what are your thoughts and observations?

The 7mm 150gr. Ballistic Tips have been my go to bullet since they came out. Matchgrade accuracy and good performance on Game. Most of my shots with it have been around 200 yds. and at that distance it makes a 7mm hole going in and a quarter to half dollar sized hole going out with the deer DRT.

If I am going after something tougher or closer, I use the Partition.

I have tried the Accubond, but I get better accuracy with the Ballistic Tips.
 
Nosler has changed the thickness of the cups on the Ballistic Tips used for big game hunting. They did it at the request of elk hunters who like to use them. By toughening them up they have greatly improved them for large game. There was an article in Handloader magazine that mentioned this. You are correct in your findings.
 
ACLakey,
Sort of OT, but how did you cut the bullet?
Nice job.
 
I stole the picture from another site. I have used different methods from a belt sander to a dremel with a cut off wheel. The best way in my opinion is to place them in a media like epoxy(low strength) and place them in an end mill. Then chip the epoxy away and you have a nice sectioned bullet. The sander or dremel methods work fine if you are careful.
 
I love shooting the 168 grain btip from my .30-06 and .308. I have been very happy with Nosler Btips in several calibers on deer size and smaller game for many years.
 
Nosler made the ballistic tips tougher about 8 or 10 years ago. Still can be bit bit damageing at closer ranges driven fast be way better. Now theyhave enough jacket to make a secondary wound too.
