GameChanger Hunting Bullets

By Sierra Tech Team

The 2019 hunting seasons are in full swing, making them the first full seasons for the latest additions to the Sierra Bullets hunting lineup. In the fall of 2018, we introduced our new GameChanger bullets. These are also seen mentioned as Tipped GameKing (TGK), but are not just a re-do of the GameKing bullets that we have used very successfully for many years.

The GameChanger bullets are actually a new design that incorporates features from other types that Sierra make, resulting in a unique and enhanced bullet style. They do feature a synthetic tip, which serves to maximize the ballistic coefficient (high BC), allowing for greater downrange trajectory and energy performance. The tip also allows us to achieve a very positive expansion over a wide range of velocities and types of game animals. The increase in jacket wall thickness ensures very deep penetration with each shot. This special bullet style gives us a true all-purpose bullet design. Our initial offerings included:

We have had multitudes of favorable reports for both accuracy and game performance. Watch the videos below to see the bullets in action.

We have received many requests for other caliber and bullet weights, and rest assured that we will continue to add to this line. Stay tuned for further Product Announcements!

    I was hoping that you would bring out a 65 gr 224 bullet that would hold up on game like your 65 gr game king did when it first came on the market!
    I bought two boxes to try on deer and got 9 consecutive one shot kills; They were maybe just a tid-bit too accurate as I wasted most of them on targets and crows!
    When it came time to re-order, the bullets I received looked the same, weighed the same but the reliability of the first lot was no where to be found! I lost two of the first three deer I shot with the one that did drop having inadequate penetration and signs of bullet failure!
    I shelved my Savage 223 bolt gun and brought out my Savage heavy barrel .308, switched to Hornady cup and core and haven’t suffered one failure since!

    Any plans for .25 cal Game Changers ?

  3. Iamaclimber 3 years ago

    I have found these in 6.5 shot in my AR-15 in 6.5 Grendel to be as accurate as any other Bullet that I have tried. I have not been able to use it to collect a Whitetail yet. The reason I am commenting on this Bullet is I have ejected two rounds after they were chambered and found that the tip had broken off during the ride from the magazine into the chamber. I have not had this issue with tipped Nosler or Hornady Bullets.
    This leads me to believe that the GameChangers need work on the durability of the tip. Until then if I use them they will be hand chambered for hunting.

    Hi, are the 6mm tgk sent to Australia? I can’t find them anywhere.

  5. Thadeus 3 years ago

    My thoughts exactly, Jerry. Would also love to see this bullet in 25 cal. Loved it with my .308 this past season (2019). Two whitetail. One was DRT at about 180, and second ran maybe 30yds. It was a 70yd shot.

    Can you please assist us on some reloading data ons the 6.5mm bullets please, if you have something in the 260Rem it would be very nice

  7. Gary Kuykendall 3 years ago

    I and I’m sure many 25 caliber fans would love to see a .257 gamechanger bullet. I would like to see it in either a 110 or 115 grain. Also, I would like to see either a 180 or 200 grain gamechanger in .308 caliber. If not the above, then please offer a tipped Gameking bullet in the weights requested above.
    Thank you!!

    Another vote for .257 here! Have had good results with .243 version. Thinking this would be an awesome pronghorn projectile.

    Can you please supply info to use the 6.5 TMK (part 4330) in a 6.5 x 55 swedish mauser, using Hodgdon h4350 powder. I would like to shoot 2750ft/s if possible. The rifle used is a Sako, 24 inch barrel, twist rate 1:7.8
    Please also supply me with the physical data of the bullet to enable me to enter the bullet on Quickload.
    Thank you

    Do you make this in the new 6.5 PRC?

  11. Jerome N 3 years ago

    When will there be a 25 cal. Gamechanger. Would definitely make a difference

  12. Casey Vance 3 years ago

    Recently used the 6.5 at 3000fps on a whitetail doe. Performance was amazing everyone commented on the wound performance. It was as close to ideal as I can imagine. Really can not say enough good about this bullet other than I too would love a 25 caliber and maybe and this is a bit of dreaming on my part but a 35 could see some use from me.

  13. Peter O Moore 3 years ago

    Please please 150gr .308 caliber bullets!

  14. Peter O Moore 3 years ago

    150gr Game Changers!

  15. Aylward Hammond 3 years ago

    These keyhole out of my 1:10 twist .243. With several loads between minimum and maximum.

  16. Eric 3 years ago

    Another vote for a .257 bullet, preferred in 120 grain. I am still super disappointed the GKHP 120gr is no longer available for my 257 Roberts loads.

  17. Joe 2 years ago

    How about getting some of these back on the market?

  18. Michael herr 2 years ago

  19. Ha 11 months ago

    Yes I have had problems with the tip breaking off. Not a good thing love the bullet but this problem needs addressing. Now.
