Hi,

Don't really again know on which forum I should post this but there seems to have been bullet discussions here, too, so I'll shoot:
Any experience of AccuBonds in comparison to Sierra GameKings?

The Sierra has a reputation of being rather soft; is this so? How does it withstand heavy bone hits (moose, boar)?

I have both in 8,2mm (.323") but haven't taken game with either. Fortunately tomorrow I'm up for moose hunt; then wild boar & roe in Austria, and whitetail and boar in January so with any luck I'll be able to some some real life testing. I also have ammo loaded with the 200grs Rhino Solid Shank.
The AB and GK look very much the same, yet the Nosler weights 200grs and the Sierra 220grs. Funny thing is, they hit at the same point of impact from my rifle. The Rhino hits a tad lower; but not so much that it would have any significance within 150yds.

In my limited testing, 140gr/7mm & 165gr/30-06, yeah, the SGK is pretty soft above 2800fps impact vel. I would not expect it to do well on bone either. The NABs, being bonded, will hold up much better across a wider impact vel. The heavier wts in SGK @ lower IV should perform well.

Thank you.
A clarifying question: Is the Sierra Game King not bonded?
I thought it is!

From my rifle I expect the 220grs not to exceed 2400fps @ the muzzle.
Factory ballistics suggest 2525fps for 200grs Sako Hammerhead so 2200 for the 220grs would not disappoint me.

The Sierra's line of bullets are great bullets and I have shot them for years, but I am slowly makeing the transition to Nosler Accubonds in all my rifles beacause of thier toughness. In all the deer and the one elk I have shot with the accubonds I have seen a smaller exit hole than the Sierras and recoverd 2 bullets that were about 60%

Don't get me rong I still love sierra's line of bullets, but as of late like the accubonds more. Next year I am useing Hornady Interbonds to see if I like them also.

I think you'll find a lot of people will bash the Sierra as too soft and praise the Accubond (I happen to like both). The 220 Sierra for 8mm is actually designed for the 8mm Rem Magnum. You say muzzle velocity of 2400 so I assume you are using a 8mm Mauser. My Sierra manual specifically says it is"too hard" for the 8x57 and will not open reliably. I would go with the Accubond for this reason.

i have tested sierra 220 grain fl S&B in 8x57 . the result was excellent about 70% weight very nice mushrooming and no jacket and core separation .

Nope:

Sierra is still the only company left in the cup and core dark ages. I have talked to them several times and asked them about making a premium bullet. They said they already made one. The gameking!!!!!

Please! premium my buttocks!

Anyway as I have stated before a company in denial for sure.


The accubond is infact bonded and it will withstand huge velocities.

See here.

Scottfromdallas is correct. Sierra specifically notes that the 8mm 220 Gameking was designed for magnum velocities, which is about 3000 fps in a 8mm Remington. With your cartridge only pushing it about 2400 fps, I would go with a softer bullet.

I shoot Accubond bullets in my 338 RUM I haven't Shot any game yet with It I been to Affica, Canada Three times Three different states So I may go to another Place to hunt.

Lars,

I general, The SGKs got the reputation of being soft and breaking apart long ago. I believe the early reputation was justified from the volume for info written about it. However, Sierra increased the jacket thickness of the GKs in response also many years ago.

I personnally, have not found this bullet to be soft. I use the SGKs for deer and hogs in my 270, 308, 7,5x55 and they have always made two holes - One going in and an exit hole! I've not found any copper jacket material either that would indicate some beak-up. Now, I don't have any experience with the light for caliber GKs - As I use 150s in my 270, 165s in my 308 and 180s in my 7,5.

I skip the Accubond in my larger caliber rifles in prefence for the Nosler partition. But I did try that 220 SGK in my 8x57. My experience was not like what yes reported. The 220 SGK would not reliably expand at my 8mm Mauser velocities in deer. Some research showed that the 220 SGK was built for the velocities expected from an 8mm Remington magnum - Much higher than you can safely push the Mauser. I switched to the Speer 200 HCs and they worked well till I rebarreled that 8mm to 9,3.

If had in to do all over, think I would go with the 200 grain NPTs for an 8x57. Not saying the ABs won't work, But why go with anything other than the tried/true performance of the Nolser partitions?!

Accubonds in a 458??????

At these velocity the Sierras will perfom just fine.

The game kings are my #1 bullet for my rifles and they have accounted for a lot of game including North Americas biggest..

I whent to the .225 gr. game King in my .35 whelen because the 250 gr. Speers wern't opening well enough for hogs. the 225 was perfect.

The 117 gr GameKing has been my favorite bullet in my .257 AI for about 30 years. I've killed at least one Antelope and deer with it each of those years, plus one of my largest 6 pt bull elk, 5 sheep and one mountain caribou. Most animals were one shot kills, and except for the elk, all bullets passed through the animals, including the caribou at 250 yds. I felt the bullets worked great.

I shot 160 gr Accubond bullets from my 7mm RM on one hunt in South Africa making one shot kills on 6 PG antelope from Mtn Reedbok to Red Hartebeest. I also used one on a cow elk. I also felt that these bullets worked great.

You should get greater penetration with the Accubonds and would probably use that one on the moose. For everything else, I would use the one that is most accurate in your rifle.

Thank you all for posting!
Took the GKs today on the hunt - alas, no luck.

It's interesting to note the differing opinions about the hardness of the GKs. The ones I have are of an old batch (10 years or so? I think); I'll give them a try for sure, but perhaps I ought not judge them without trying a new batch, as well.

- Lars

GKs seem to be quite accurate in the rifles I've used them in. I took them on a BC Black Bear hunt several times, with great results out of a Rifles Inc in 300 Win Mag. If they were too sift, the Bear didn't complain. I still have the 2 bullets on my bench.

That was my mistake I should have said 338 RUM Not 458 Lott.

I used to shoot GameKings through my 257 AI and .280. I have been shooting the Accubonds for the past three years and love them. Perfect bullet performance on several of the recovered Noslers.

Yes, the Game Kings are NOT bonded!!
