several of my rifles love these bullets. I have not put one through an animal so I have no idea on bullet performance. I would like to hear your opinion of these bullets.

.257 90gr HPBT approx. 3580fps
.277 140gr HPBT approx. 3000fps
.284 160gr HPBT approx. 2900fps

My opinion of Sierra bullets is that they are usually among the most accurate you can buy and they are quite affordable. However, IMHO, they have fallen behind other companies by not offering a premium bullet with either a bonded core or some other mechanism to control expansion. I harvested 3 big whitetails with the .277" 140gr SBT bullet and was not pleased with the performance from any of them. In 2 of the deer, the jacket very clearly separated and the third deer went nearly 200 yards before it dropped. I would not expect the hollow points to perform better, unless you consider rapid expansion good performance from a big-game bullet.
The Gameking is really designed for longer range shots with the caliber it's designed for. I don't think they show any kind of "best performance impact velocity" but that is what the shooter needs. The bullet is very well made, but the shooter has to know what kind of shot they are likely to take before they choose the Gameking as their bullet. My very loose rule of thumb is minimum of 200 yard shot with most cartridges to use this bullet. I would think that if you call Sierra and ask them about a specific bullet, they would tell you what impact velocity the bullet will perform best in your specific caliber/bullet weight, and from that you can decide if it's the right bullet for the ranges you are likely to take shots. At the right impact velocity, they are an excellent bullet, usually very good BC with a boattail design, so less drop and less wind drift - exactly what you want for a bullet used on longer shots.

You're 100% correct, but what if you go out expecting a 200 yard shot and a trophy mule deer buck pops up out of nowhere and he's 35 paces away? Do you patiently wait for him to bounce off and whistle when he gets to 200? A good big-game bullet is not one that performs perfectly at a specific distance; they ALL do that! The ideal big-game bullet opens up and holds together at 30 feet while still expanding and penetrating completely, at 400 yards. The Gameking will probably be great at the longer range, but I know from personal experience that they do not hold together well at 30 feet.

Core-lokt, Partition, X bullet, A-Frame, Accubond, Interlock, etc...These are quality big-game bullets and they are well worth any additional cost, or the loss of gilt-edged accuracy, for the performance on game that they provide.

Carry two different loads? Ridiculous. Adjust the distance you shoot based on the bullet you have loaded? That would be very accommodating of the game being hunted.

The Partition penetrates reliably, even when the front core separates completely. This causes dramatic wound channels and an exit wound for easy tracking. The SGK just blows up and if/when the animal runs off 150 yards, you've got a much tougher job finding it.

The Gameking is a target bullet, masquerading as a hunting bullet. It uses a simple, drawn copper jacket; technology that is pushing 100 years of age. Sierra makes some of the best target bullets in the world...the SGK is one of them.

We do agree on one thing: The Accubond is a very well-designed bullet that performs well irrespective of distance or impact velocity. It has an excellent BC and would be just as capable on that 500 yard sheep as the Gameking, but if you happen to peek over the top of a ridge and see one at 50 yards, you aren't going to wonder if the bullet is going to perform.

You always carry cartridges with 4 different bullets loaded in them, for your 264WM? Like, you're walking around, hunting deer or something, and you've got 4 different loads with you? Do you have a gun-bearer along with you, toting all that ammo? :D
I have a ammo belt that holds 30 rounds and a fanny pack with rain coat, extra gloves, wool hat, rope, t.p., matches, plastic bags, food, two water bottles and 20 rounds of 140gr bullets. You never know when you will make contact with the enemy. When deer season is open bear season and cougar is also open plus varmints.:D
So, you carry 50 rounds of 264WM ammo, on any given hunt? And you sight in for 95-100gr bullets, and use Kentucky windage when using the 140gr bullets, for shots on big game? Do you have drop charts for each ammo type, with allowances made for differences in how your rifle is sighted in?

I've gotta be honest with you, here...the logistics of what you're describing would make the whole endeavor a lot more work than I am willing to undertake, when all I really wanted to do was go huntin'. Couldn't you just carry 10 rounds of the 140gr bullets, sight in for such, and use those for any shot that presents itself? I'm just askin'... :)
You guys are drifting woefully off topic...

Anyway, the .257" 90 grain bullet the OP asked about is a varmint bullet, says so right in Sierra's 5th edition manual. They have a very large hollow point and the jacket is very thin, which contributes to accuracy, but makes them quite fragile.

Sierra is quite a bit behind the times in bullet development, they don't even make a true tapered jacket bullet let along a bonded core bullet or partition type bullet and have neglected the all copper market. Not a good sign for them. They do make good plinking and match bullets, and they tend to shoot well from my tests, but I don't think I'd use them on game.

You're 100% correct on all counts, Matt. I was basically yanking 264's chain and for that I have been duly chastised. If Sierra found a way to make new bullets that are just as accurate as their current line-up, but with more reliable and consistent terminal performance, they would give Nosler a run for their money. I don't know how long they can hang on as primarily a plinking, varmint and target bullet manufacturer, but I remember a time when they were THE bullet company, with everyone else chasing them. Seems like they've been caught, passed and just about LAPPED, at this point.
Sorry for this reply being off topic. I don't have any idea how many bullets are sold each year for hunting vs target shooting, but I know I hunt and shoot competitively and I shoot nothing but Sierras in competition and if you go to a High Power or Silhouette match from what I have seen Sierra totally dominates all other brands. I shoot probably 10x as many Sierra bullets for match shooting as I do for all other brands of bullets combined that I use for hunting. One 3 hr silhouette match can easily consume 100 bullets. I don't ever buy Sierra Matchkings in anything but the 500 count boxes. I do use Sierras a little for hunting as well and have found them to work just fine for deer. All I'm saying is that I am not sure they are in such dire straits as you suggest. I think there will always be a market for an affordable, accurate bullet and target and varmint shooters put a LOT more rounds down range than a guy who just hunts big game.
You are undoubtedly correct about the target crowd using a lot of bullets, but where there are tens of millions of big-game hunters, there are relatively few shooting target competitions. Any company whose product line is gradually reduced to just a few profitable items risks going out of business with just a small change in legislation or consumer sentiment. If the anti's get their way, the entire nation will follow Kalifornia on this absurd track of lead-free bullets, and if that happens, Sierra is a thing of the past. If they were part of a larger corporation they might survive, but being a privately owned company, they are potentially at risk if the market changes.

Perhaps more on-topic, I love Sierra bullets and will always use them for some of the shooting I do. They were the first bullets I handloaded and gave the kind of accuracy I had only read about, previously! Also, they used to be much more commonly used by other companies who were making ammo. To a lesser extent, they still are, but I really wish they would take what they know about making accurate projectiles and combine that with the modern technology used for making tough bullets. That way, they could offer a product with better terminal performance to compete with the likes of Nosler, Speer, Hornady and Barnes.

Don't take this personally Chief Rid, but any 22 centerfire would have dispatched a deer that size, in roughly the same distance. What was it, 8" across? Deer aren't the best means for testing penetration of a big game bullet, because of how thin-skinned and lightly boned they are. In fact, well-constructed bullets often don't expand much at all on a deer, though they surely kill them just as dead.

Were you shooting a 30-'06 or a 308 Win for that hunt? He looks like he'll be great table fare for the winter! Good job putting him down quickly. :)
BT, have you compared the Accubond and HPBT, "over long shot groups"? Also, have you shot a representative number and variety of animals with the Accubond, such that you are qualified to state that it does not offer better terminal performance on game than the Sierra bullet you have had so much success with? Do you also feel the Sierra HPBT offers better performance than the Nosler Partition, irrespective of their relative accuracy? The problem with blanket statements is you sometimes get smothered in them...and I would know! :)
The Accubond was only released 9 years ago, so I'm presuming you are combining your Partition and Accubond experience into one big pool. The Partition isn't a "bonded bullet", but is definitely a very consistent performer, even if it's not often one-hole accurate. In my admittedly limited experience, the Accubond IS very accurate, with 1" groups at 100 yards not too difficult to attain.

Shooting southern deer with 300 Magnums may not be the best test of terminal performance because, as you stated, every single one is a pass through. No surprise there, but I do wonder if you were to be fortunate enough to harvest a like number of elk, or nilgai, what the results might be. As Nick stated earlier, Sierra did some testing and came to the conclusion that whatever differences might be quantifiable, they aren't enough to justify changing their extremely accurate bullets. For light, thin-skinned (CXP2) game, I'm not sure the bullet matters much at all, so excellent accuracy is something to consider as a defining characteristic.
