I'm looking at both of these bullets for both my 300 WSM and Rem 700 3006 (backup Rifle) for elk. How are these 2 bullets different and similar and which would you prefer for shots from 0-400 Yards?
Thank You!
Thank You!
Great synopsis, I learn something today. Thank you for sharing ,@FinaddictionsI think of these two bullets as completely different families even though they are both bonded, and they both have plastic tips. The trophy bonded tip is a monolithic or solid shank at the rear, with a bonded lead tip and a HEAVILY tapered jacket to slow expansion so the bullet will retain a very significant portion of its weight. It has a fairly deep hollow point and the jacket is skived, meaning it has light cuts in the jacket to help start the expansion, but the heavily tapered jacket helps to keep it from over expansion. They generally will maintain mid to high 90 percentiles of their original weight. Because they are a heavily worked bullet in the manufacturing process, they can sometimes be a little more finicky to get to shoot well because the hard jacket and solid shank sometimes don't engrave the rifling quite as well.
The Accubond is a bonded bullet that does have a significant portion of its weight derived from the jacket material, but the lead core does go all the way to the base. It's also heavily tapered, but not nearly to the extent of the trophy bonded. The design of the Accubond is to mimic the performance of the Partition but with a plastic tip. It does a good job at this, opening quickly and shedding a decent amount of weight but maintaining the rear portion of the bullet for penetration. They generally will retain 60-70% of their initial weight. Because of the gilding metal jacket these generally engrave the rifling very well, and can be very easy to get to shoot in most rifles.
Overall the Accubond will give you a more devastating wound channel with slightly less penetration and kill very well. There will be more blood shot if you hit meat or bone. The Trophy Bonded Tip will give you deeper penetration, less blood shot but also a less devastating wound channel. You have to pick what you're looking for. For thin skinned game I love the Accubonds, and they perform wonderfully even on larger animals, but you have to understand they can have some large wound cavities and blood shot on the entries, while the TBT will have much less blood shot and less devastating cavities so excel at larger game like elk, moose or eland.
Both are excellent designs and I've used both quite a bit. I generally prefer the larger wound cavities of the Accubond because the animals often die very close to where they were shot, especially when targeting deer/antelope sized critters. I like the TBT's a lot when I'm hunting elk or larger game for the dependable straight line penetration.
Thanks for the reply, and I hope you have a fantastic hunt!Good morning, I'm new to the site and am heading to NW MT this September for my first elk hunt.
@Finaddictions- your response was exactly what I was looking for to confirm my bullet choice. I built a custom .308 for this hunt, and have 2 boxes of 180 grain Federal TBT waiting to get sighted in... Thank you for the thoughtful and detailed response.
The Partition is the original controlled expansion premium bullet and is amazing for the fact that it's still a premium bullet and is completely applicable to todays hunting markets.How does the Partition compare to the TBT and Accubond?
Thanks for the great response above!!
Huntdoc, the Accubond and Partition will act very similar, although the Partition has a slight edge here. They'll both plow on through, although the Partition has a good chance of dropping it's nose and just driving through with the base on a hard shoulder impact. The TBT is gonna just plow right on through and maintain the mushroom on the front. It might not penetrate quite as far as the Partition in this scenario because of the frontal mass that's maintained on the TBT. Of course it's always hard to say exactly what would occur because every single shot instance is always a little difference. Suffice it to say, that I wouldn't worry about using any of the mentioned bullets shooting through bone.How will each respond to placement that hits bone before vitals? Wondering which is more forgiving of poor placement. Better placement is the goal but things happen.
Apples to oranges comparison. Nothing against the Partition, as more big game has probably been killed with Partitions than any other bullet on the market. But they are a ballistically inferior bullet IMO. Flat base, broad lead tip. They were revolutionary in their time, and they can be very accurate for sure. The Accubond (and TBT) are a plastic tip boat tailed bullet with a high ballistic coefficient which makes them better for longer range work.How does the Partition compare to the TBT and Accubond?
Thanks for the great response above!!
So of the three options discussed, you would choose the TBT for elk assuming they all shot equally well out of your rifle?The Partition is the original controlled expansion premium bullet and is amazing for the fact that it's still a premium bullet and is completely applicable to todays hunting markets.
The Partitions design is essentially two cup and core bullets separated by a partition. The front of the bullet readily expands, and will even often lose its front core, but the back of the bullet is essentially a full metal jacket at that point and it will continue to penetrate. Because the front of the bullet is a cup and core with a tapered jacket and a fairly soft lead core, it expands rapidly and creates a pretty devastating wound cavity, and then the back of the bullet continues to penetrate. Most of the Partitions are designed to maintain about 60-65% of their weight, but as you move up in caliber size and bullet weight, some of them have harder cores and the partition itself is moved forward so they maintain even more of their weight. I think this migration towards harder cores and forward partitions is the .30 cal 180 grain bullet, but I would have to check with Nosler to be sure. These bullets will often maintain 80-85% of their bullet weight.
As mentioned above about the AccuBond, this bullet was designed to have a plastic tip, but essentially give similar performance to that of the Partitions. Often the jacket alone will be 60-65% of the bullets total weight, hence the way they will often have similar weight retentions to the partition.
Actually not generally. I think they're amazing bullets, especially if you're going to shoot for bone or high shoulder type shots. I'm a behind the shoulder guy and the Accubond is by far my favorite bullet. It's such a great combination of a bonded bullet that will penetrate, but yet it sheds enough weight and opens fast enough to create really good wound cavities. In my experience animals just don't go far. I killed my elk this winter with one and it took 3-4 steps and died. What better performance could you ask for?So of the three options discussed, you would choose the TBT for elk assuming they all shot equally well out of your rifle?
