6mm 90 grains Game changer and Accubond

Make a small difference out past where it is important. Pretty bullet though.

Agreed on both counts

Here is a 165 Gamechanger (on left) next to a 165 Ballistic Tip.

Good lookin sleek boolits...

The Gamechanger seems to be not as stoutly constructed as the Accubond

Took them out to 600 yesterday and they were sure doing a good job of bucking the wind...

Legit question, not being snarky. What is the basis for you comment.?

Lighter, thinner jacket, hence you can make it longer and with higher BC, if that's important to anyone.

Another question: what does this bullet offer that we don’t already have a dozen of? Seems to me there are lots of tipped cup and core bullets out there. Catchy name? Wonder if Hornady will tell us that the tips melt....

look at the cross section of the bullet jacket on both bullets especially the base . Not sure that the Gamechanger should be compared to other LR bullets other then an Accubond

Bullets have a cool translucent green tip, that ought to mean something to someone. I am going to try them in a 7 mag and 06

In my case, it offered better accuracy over Accubonds and BTs both. In general, I've found Sierras to be consistently accurate across their entire line of bullets. Since they didn't offer a plastic tipped, high BC hunting bullet I always looked elsewhere for that need.

This bullet fills a niche Sierra didn't previously have any offering in. I can't say it's "better" than other offerings out there, but I'm a fan thus far in my limited experience.

Dave

This is just a question: Are those sooooo long that either: (1) you must seat them so deeply that you lose case capacity (i.e., velocity); or (2) the cartridge will not fit in a standard magazine?

Where do you see cross sections of both bullets, especially the Gamechanger? I've seen Sierra's "picture" on the ad but I don't think it's a real picture. If someone has dissected them I'd like to see the real deal.

Pretty neat vid:

Is the claimed BC on or???????????????????

They are not but if they rival the newer BT's in construction I will be happy

Looks like a nice bullet to me, especially if it is indeed more stoutly constructed than the Gameking.

Options are nice.

From Sierras site.

Fotis,

I'm by no means an expert, but from every range between 200-600 things dialed spot-on with the SWFA 3-9 and the ballistic app on my phone.

Dave

Sierra has long offered a hollow point Game King that has a much tougher jacket than a regular Game King or a Match KIng.These bullets have a very large hollowpoint and the BC numbers were not that good. But the terminal ballistics were really great. These things would expand and penetrate well.

I bet the jacket on the new tipped bullets is heavy like on the old hollow points. If so,I bet they work great.

Dave,

Which app are you using?

BulletDrop. I'm sure there are better, but it was free and I'm cheap.

I’m using the same... 🤣

If I may, how do they compare to the Nosler LRAB?

Did I understand correctly that they use a copper jacket?

Most bullets have gilded metal jackets. I wonder about the thickness of the jacket also?
The original Barnes and Swift both have copper jackets. I believe the original Bitterroots also had copper jackets.

Fotis, could you cross section a bullet and report on jacket thickness?

Substantially less bearing surface on the Sierra, that is a plus, but it's not a bonded bullet so to me that's sort of Apples to Oranges comparison.

Seems like a comparison to a Ballistic Tip would be more same same.

Mike

I tried your application and downloaded it but it doesn't work for me. even though I have all the fields, filled out it's still asking me not to leave any blanks which I have not

I concur with your assessment

Jacket thickness may not tell the entire story, In the past when Sierra wanted a tougher bullet part of their solution was a higher antimony % for a harder core.

Nosler on the other hand has some beefy jackets on some BT's and AB's.

Their video on youtube shows a shoulder bone (which was inserted into ballistic gel) being hit and the bullet retrieved looked really good.
What they did not tell you is that the bullet (fired from a 284 Win) impacted at 2500 fps only. That was disappointing to me. Most C&C bullets would react the similarly.

I have had enormous success using cup and core bullets at launching velocities of less than 2800 fps.

That is their primary Forte. Those speeds

And those speeds are pretty useful in the scheme of things.

I would be astonished if the Sierra Game Changer is even close to the toughness of a Nosler BT. The BT is about the toughest cup and core bullet out there.

Another choice, and that`s good because rifles can be fussy. I've had good luck with the 165gr GK HPs and some of their others too, but deer are easy.

Gotta wonder if, with that long nose, it'll be hard to get close to the rifling, and if it'll matter in my rifles. I'm sitting on so many bullets now, I may not ever get around to these.

Larry will report on these soon and let us all know........

Range report. Sierra GameChanger in my 240 ultralight backcountry Weatherby. 2 different loads terrible grouping from a 1 to 10 Barrel even at 3500 feet per second. For reference those are three inch circle stickers

I think any comparison should be with the Nosler ABLR. The only difference is the ABLR is bonded while the Sierra is not. Ballistically they should just about be the same. They do look a lot more like an ABLR than a BT to me.

What was your OAL?

I am something like 2.920 in my 6mm Remington and barely off of lands. Pretty sure i can't use them at 2.8" without ogive being below case mouth. If they shoot good I will just use my rifle as a 2 shot gun like I have for years with my coyote loads.

I like the different color tips of the Ballistic tips. I have 7 mags and 264 Win mags. The different color may help keep me from lighting off a 7 mag in a 264. The 7 mag may not chamber in a 264, I’ve never tried it.

Coal was 3.1. I don't think any seating depth adjustment would make that big of a difference

Odd.....I shot two groups less than 1.25" at 200 yards Saturday with the 90 grain out of a 10" twist 243. Velocity was just over 2900 fps. I'll increase my powder charge and see what happens. Hoping to get them to 3100.

Same here (liking the color difference) ut that didn't stop me from chambering a .280 Rem in my .338WM in the dark.

Damn...You think it could be my brand new 3x9 Leupold VX2 CDS I just mounted?

I broke the shrinkwrap. HUH!! got me wondering now!

Before I had a 4.5x14 Burris on it. It shot like this but wanted something lighter on the rifle.

I just hope they don’t DC the game king!!! Most accurate bullets I’ve found in two of my guns

Fotis - what group size measuring software is this? Thanks.

That's good to know, what powder?

RL16. Thinking of giving IMR4451 a chance too

Bump

Anyone toss a new Tipped Gameking into an animal?

I like Ballistic tips and Accubonds, I’m going to try the tipped gamekings. The Ballistic tips are nice because of the different color tips.

This came out of my wife’s cow she got a month ago. A 140 Gamechanger from a .270 Win. 100 yard shot, quartering too, entry in the point of the shoulder, through the big leg bone, recovered under the hide just behind the opposing shoulder. Weight retention is 52%. It was the first animal our family has taken with them but will not be the last.

Great photo!

That’s a beautiful recovered bullet.

And congrats on the elk.

I shot four deer with the 130 Gamechanger. One each lung, high shoulder, high neck, and front shot. Bullet acted very similar to an accubond in that it did not over expand, but initial expansion was faster than the accubond. I have a full write up on accurate shooter under the reviews section. Very impressive bullet.
