This is the same velocity that I run my .270 Win/150 gr. Grand Slams, and they work very well also.



But for a high BC tipped boat tail cup-n-core, w/ that much expansion and retention?

Impressive.

interesting

That penetration/expansion is easily accomplished by many bullets. Pretty bullets though.

Looks unremarkable to me. Typical nonsense YouTube feel good video. What’s going to happen if he shoots the bullet into a deer and the expected results of the recovered bullet are not the same? Hilarious that the 1/2” group raised his confidence in his Tennessee deer rifle. I wonder how far his average shot is on deer there.

I love Sierra bullets for accuracy and I have shot quite a few critters with the 30 cal 180 and 165 BTSP gameking. The cores separated about half of the time so I was surprised that they stayed together for him.

The 150’s work well in a 308. They are great bullets.

I’ve not yet shot game with them, but my 6.5 likes the HSM loading with the 130s and 140s and my the -06 the 165s.

Yeah these bullets have quite a high failure rate. Not even on my radar, but buy whatever you like I guess.

What do you consider failure?

In this case core/jacket separation and fragmentation.

I don't have a SINGLE green box of bullets in my stash !
There are reasons for that.

Did it kill the animal?

More accurately, your expectations didn’t meet reality.

Really?
Just because a bullet kills an animal does NOT mean it lived up to design performance.


Some things just won’t go away.

So true, however if the result in question is not a claim made by the manufacturer then its not a failure. For example, I don’t see any claims made by Sierra that the GameKing is designed to retain its jacket, therefore if it looses its jacket, it’s not a failure.

I’ve got some 165 SGK sent to me by mistake but they shoot well, actually close to my hunting load POI. Never been a fan of boolits known to come apart. We’ve got a cougar hanging around and they have his name on it…..Sylvester

Ive hunted quite a bit with Pro Hunters and GameKings. Frequently they have lost jackets but they always worked well for me. Great CC bullet I think.

Exactly. Gut shooting an animal with a 22 will kill it. That doesn't mean it's an effective and humane means of hunting.

Similarly, the wounds from frangible bullets will eventually kill and animal. But the animal may go a very long way. The whole purpose of a well though out hunting bullet is to maximize the chance of an expanded straight-line pass through. That way you damage whatever vital organ(s) and support bones you lined up your shot on, and have a good exit wound blood trail to follow if the animal doesn't go do wn immediately.

The SGK is a failure at this basic task. There are plenty of bullets that do it much, much better. Now, people can shoot whatever the hell they want within the game laws, but a smart hunter will use a better bullet. The cost is trivial compared to the benefit.

Just a failure to meet your expectations.

Dead is dead. Been using Sierra bullets for many years. They are accurate and will work on game.

Only "failures" I get from em is the deer fail to live.

Yeah they separate and yeah they are hard on meat but they kill like lightning.

Been around Sierras more than any other bullets in the last 40sh years. The sumbitches flat ass kill critters.

Sure I kill deer w Partitions, Interlocks and several others but I can't see that they work a lick better than Sierras on little old whitetails.

Y'all need to be glad. I am not competition for Green Box bullets. There's more for you.

If you are using a heavy-ish for caliber bullet at a moderate speed, I think Sierra GK bullets are great for deer. It's when they are used up close and cranked up near 3,000fps or are lightweights with low SD that things get dicey with them coming apart. Not much different than other cup/cores like Powerpoints, Speer BT, Core-Lokt, etc. Cup/cores like this are great killers in the 7mm-08 and .308 and often exit.

I use em at 15 yards out to max range.

55 grain Gamekings in .224

PH and GK 80, 85 and 100 grain in the 24 calibers.

GK 90 and 100 in 25s

PH 120s in 6.5s and 7mms.

PH or GK 150s in 30 calibers.

They work for me.

My favorite Sierra bullet is the 160 grain 7mm Gameking. Perfect for the 7x57.

I made a (crappy) youtube video on the .277 140 Game Changer a few years ago when it first came out. It's very accurate in my Mod 70 Ranger.



My wife tested the expansion and penetration as well on them but her test media was very large cow elk shoulders.







2018 Report on this bullets

The next year she used a 130 Nos PT. This year she is using a 150 Horn SP. The 140 .277 Game Changer worked great for us but so does a bunch of other bullets.

Good luck and thanks for the post.

Todd

Nice looking family, Todd... Thanks for the report.

When you say "these" bullets, are you referring to these exact bullets, of SIERRA bullets in general?

And, if these bullets specifically, from what source?

Your reputation here proceeds you, and it doesn't call for a bow.
