Let us know how they shoot, I was turned off by the low BC number they initially quoted me prior to release
Sierra Gamechanger a good attempt to compete with Nosler Accubond but failed at the bonding attempt.
They're not bonded so I'm not sure how they failed at something they didn't try to do.
I killed probably 12-15 elk with 160gr Sierra Game King our of a 7mag. Never an issue of dying on the other end. My good friend and his dad killed probably 25-30 combined with the same combination.
I want to say that my experience with the Sierra Gamechanger in .30 caliber has been outstanding. I'm a deer hunter from Oklahoma and have always reloaded my ammo, mainly 25-06, typically Sierra Prohunter or Gameking. I just returned from an African Safari and used the Sierra Gamechanger in my 30-06, a gun I've had for over 40 years, but rarely fired. Honestly I used the Gamechanger because it was about all I could find. There just weren't any Accubonds or A-frames to be had. Having never been to Africa before, I spent a lot of time researching bullet recommendations, but without availability, my choices were limited to the Gamechanger or the Barnes TTSX. Since I was building the ammo for myself and my partners rifle, I fired over 300 rounds prior to the trip, just checking accuracy and consistentcies. Also, I had to learn to shoot off sticks since I was told that our shooting would all be from a standing position, out to 300yds. Anyway, I chose to take the Sierra because it was just so reliably accurate. However, I took the time to section a Gamechanger in both directions and actually compared the thickness of the copper jacket to other 30 caliber bullets I had and it is very clear that the Sierra Gamechanger is a very tough bullet. I took 15 animals while I was there and had exits on 14 of the animals. Not one required a second round. I harvested Zebra, Kudu, Hartebeest, Wildebeest, Gemsbok, and smaller animals. My load was 56.1gr H4350, with a 165gr Sierra Gamechanger, CCI primer. My longest kill was just under 300 yds. Unfortunately, when shooting a Blesbok, at 175yds, the bullet passed through and killed a second animal that I hadn't seen come in at the last moment. I've come to understand that bullet placement is the most important factor, in a clean kill. Shoot the bullet you like, for whatever reason, just shoot it accurately. We have lots of really good choices, Gamechanger's, being one of them.
I’m currently using the 165 gr Gamechanger in my .308. 3 whitetail deer so far, each a one shot and drop. All have been pass through shots with some bullet fragments found in the exit wound. I’m leaning toward these being a great deer/antelope bullet, but possibly a little too explosive for elk and bear. I’m not sure the penetration will be adequate on tough critters.
Just my initial thoughts, but I’m seeing large chunks of copper in the exit wound and in the body cavity.
With .300 Win or 6.5-300 Weatherby you’ll see fantastic range results. 3” high at 100yd and you’ll have a 400yd+ laser. Performance on game with the Accubond may be better or maybe that’s just advertising. Because I think a reconfigured GK is what we got here. And the original GK was no slouch. Whereas the Accubond was a more accurate bonded bullet because the Partition was perfect in every way at hunting distances.
Not sure if I can add any value to this thread but I bought 1k of the 165 GC this spring and have loaded them in 308, 30-06 and 300 WM. Admittedly I ordered them as 2nds but extensively measured and sorted by weight, BTO, OAL and even measured from start of boat tail to the end. I’ve tried several different powders between the three cartridges but the only one I could get to group was in my older neighbors 30-06 with H4350. My 308 and WM are newer, higher tolerances and much higher end barrels, actions, well everything… but the 06 is the only one I could get them to shoot well enough on. Very common to have 2 touching with the third a half inch ish away… the node I settled on is also very conservative even for an 06. He’s elk hunting with it this week so no report on terminal performance yet. I am also loading for my nephew’s 6.5 needs more (Creedmoor) currently and am considering loading the 130s for it. I’ve got a couple great loads for the 130 gr Berger’s I’m hoping will be close…
