The front core is gone, that is normal for a Partition.That should be a nice rifle in one of the "good" weatherby chamberings. (Sorry not a weatherby fan, but I like the .340). Just wondering, did the lead core come out of that partition bullet? It looks like an empty cup in the top there, or did it hold together at the partition? And did you weigh it afterwards? I'm thinking of running partitions in my .270, choice is between them and Woodleighs which I know are good performers.
The front part of a Berger will fragment, then the rest expands. They make a Target only bullet, and a Hunting VLD.That's impressive performance alright. I didn't realize it was normal for Partitions to shed the front half of the core. Always thought bergers were a match grade target bullet, do they make a controlled expansion hunting projectile as well?
Berger Bullets said:Hunting Bullets
The Hunting bullet line is proving to be the most lethal big game hunting bullets available. All of our Hunting bullets are made in the VLD design. The VLD design incorporates a sharp nose that allows the bullet to penetrate 2” to 3” before it starts to expand. After the bullet starts to expand it will shed 40% to 85% of its weight as shrapnel into the surrounding tissue (internal organ). The combination between the shrapnel and the hydrostatic shock produces a massive wound cavity within the vital area (internal organs) that will be 13” to 15” long. This massive wound cavity results in the animal dropping fast since most go into shock after such a tremendous blow. Those animals that don’t go down immediately will soon succumb to blood pressure loss and/or organ failure producing a quick ethical kill. Our bullets don't poke through like an arrow (high weight retention, deep penetration bullets) but instead dump their energy where it is most effective, inside the animal. Using the Berger VLD will result in an animal that goes down fast so you can enjoy the results of your hunt without having to track the wounded animal after the shot. You owe it to yourself to see how accurate and deadly the Berger Hunting VLD will be on your next hunt.

I don't understand why a high B.C. makes it a "Brown Bear class" bullet. Why do you regard it so?Tons of good info and reviews on the Bergers at longrangehunting.com . Those guys are the reason I chose to give them a try. They are known for their accuracy and BC's, so thats a huge bonus for me. Having a 210gr bullet with a .631 BC is nice. I think that puts my .300 Ultra Mag in the Brown Bear class for sure.

I have always valued Sectional Density over B.C. when it comes to terminal ballistic performance, and would not consider anything less than 250 grains in the .338's for the biggest bears. B.C. to me is about retaining velocity at long range and flattening trajectories as a result, but a high B.C. is not important at big bear ranges. Sectional Density is essential for penetration.
Tang, with all due respect for your passions and your shooting ability and my respect for you as a gun lover, I would never use a Berger of any size on a brown bear especially a full grown male. It is not the bullet to use. Have you ever been in the presents of a big brown and taken him. It will change your mind in a heart beat about using a Berger on a Brown. Now If someone told you they did or that it was ok to use and recommended the use of one on a Big Brown, I say up front and with no apology "THEY ARE FULL OF IT"!!!!!!!!!!
And just how far away do you intend to shoot at brown bears?I just meant it makes shots easier to make, with less compensation. Dont read so much into it...lol
A .308, 210gr has a SD of 0.31624 per Point Blank SoftwareThe sectional density of a 250 grain .338 bullet is an excellent .313 while a 210 grain has a S.D. of only .263. If you think that difference is not worth thinking about when shooting large dangerous game such as brown bears, you need to read about what sectional density means, and how important it is to terminal performance on game..
Sorry. My mistake. Didn't see the .30 cal. note and thought we were talking about .338 cal bullets.A .308, 210gr has a SD of 0.31624 per Point Blank Software
Sectional density of 0.316 with a bullet weight of 210 and diameter of .308". Per Beartooth Bullets calculator.
Sorry. My mistake. Didn't see the .30 cal. note and thought we were talking about .338 cal bullets.
The sectional densities of any .30 cal over 200 grains are very good. That is why the 220 grain loads in the old .30-06 are so effective on big game at close range. They have a S.D. of over .330 that would put them into big bear load range, although they have very poor Ballistic Coefficients.
I like the 250 grain nos partitions in my .338 WM, but i have not had a chance to test on elk or bears yet, not really any reason to after the performance i got out of the 225 gr partitions, maybe spring bear will be the excuse i need.Final Component Adjustment
