Sierra tipped gameking (gamechanger) feedback.

The 165gr Game Changer out of my 308Win is the most accurate bullet i've shot. It shot slightly better than the old 168gr SMK. I tried them in my 7mm Rem Mag and they didn't do well but better than most any other bullet that i've tried shooting from it. It's a problem child so I don't discount the 7mm Game Changer.
I tried them in my 270 Win and so far they are working well. I need to fine tune them a bit but I think they will be very accurate.

I did shoot a Cow elk with the 165gr 7mm last season. Head shot so nothing to report on terminal performance. Any bullet would've done the same.

Where did the seating depth tune on them? Long jump or closer?
 
I loaded the 22cal 64gr for a guy this summer in a Bergara 22-250.

They took a little tweaking but I got them to shoot around .6-.8 moa for a 3 shot group which is as good as I got it to shoot anything.
 
I use the 165's in a 7.82 Lazzeroni Warbird at 3505fps. Loaded to a sako's short mag length and shoots great. Shot a mule deer in nebraska at 826 yds. I was happy with the terminal performance.
 
Sounds like these bullets may do well with longer jumps to the lands. That doesn't surprise me with the jacket being thick & tangent ogive. Not saying that someone couldn't like wise have good results closer to the lands.

Tangents are very jump tolerant. Hornady's love to jump.
 
I have tried both of the 6mm's & they grouped well in the 6x47L I was testing them in. I do think due to their length a fast twist barrel may help. Mine was a 1:8 twist. Just my limited experience. I may try the .30 cal. in my .300 WSM in the near future.

Yea, I haven't measured them but the thicker copper jacket has to make them longer for their weight. I'm guessing they will like a faster twist for their weight than some of the other low drag bullets of the same weight.
 
I don't think they have thicker jackets at all. I think they're the worst bullet I've ever shot thru my 264 win mag. Running them through my milk jug test at 100 yards, they only penetrated to the 3rd jug, and all that was left was dust and tiny pieces of copper jacket. My 257 Robert's with 100 grain bullets even makes it to the 4th jug and retains about 70% of weight. I bought a box of 100 to try. Loaded up 3 rounds with same load as I load swift sciroccos. Shot 2 to see if they were about the same poi as the swift's, which they were, and shot the 3rd round into the jugs. The other 97, I gave away. I'm done with sierra anything. For hunting, I'll take swifts any day over anything. Killed a 300 lb boar hog last fall with my ruger no 1 in 25-06, and 100 gr swift a-frame. Dont get any better than that.
 
Just wanted to see who has shot the TGK (game changer) and how was accuracy compared to other bullets.
The 165 in 308, not well at all in M700 308, shoots fine in Armalite AR10, but probably not as well as 150 SST, no reason to buy anymore for me.

Send them all my way. I'm glad we all have opinions but the fact is, for me, they are some of the best shooting and performing bullets I shoot. Pretty on par with many other hunting bullets. Just shows how everyone's experiences are different. Of course I don't run them at the speeds of a 264 win mag. Killed 3 whitetails and found 85% of the jacketed bullet mushroomed under the hide on the opposite shoulder. That is text book hunting bullet performance IMO.
 
I'm currently shooting the 180s out of my 300wby at 3250mv. Just got back from a goat shoot (audad and catalina) . Shortest shot was 300 yards and the longest was about 650. They performed well. I didnt recover a single bullet. Most animals were DRT.

Haven't reloaded them yet, but out of the box factory 90 grain rounds in my out of the box .243 Winchester XPR shot 0.5" groups at 100 yards. If I have them measured correctly, the factory rounds have the bullet seated 0.030" off the lands of my gun.

Shot two deer with them this year. The doe I shot at 120 yards dropped where she was standing. The buck I shot a week later at 60 yards ran 40 yards before dropping 10 feet from where the doe died.
