Home Forums Reloading Big Game Rifles Sierra Gamechanger

Are any of you using these bullets? I’ve heard the accuracy is awesome, just wonder how they perform on game?

I used the 90gr 6mm in my 6mm/284 with a good dose of Retumbo on Mule deer, whitetail and antelope. all broadside, complete pass through with ecellent accuracy.

The only way I will post about poor bullet performance on the campfire is to......never do it. One reason I have seldom posted here in the last few years. There are more tolerant firearm forums around where the propensity for character assassination is not a prerequisite to join.

I plan to put a 130 through bear shoulders soon, I’ll post here again if it happens.

I would also like to hear about this bullets on game performance. I loaded up some 165's for My .300 WSM Subalpine and they shoot 5 shot 1 hole groups @100yds so they are definitley some accurate bastids......Hb

The 130gr 6.5's with 38.5gr of RL15 has accounted for a bunch of 1/2 3 shot groups from my Bergara 6.5 Creedmoor. Will likely use them on mule deer this fall - unless I draw an elk tag. If that happens I'll most probably work on a 140gr load.

Wow...seriously? Not doubting you at all but, while I am a "new member", I have lurked for years and never really noticed it. Some of the other sites where you find numerous basement-dwelling operator types preparing for "SHTF" and trying hard to out macho everyone make this place look like a church social. And God forbid you even attempt to defend yourself from an attack by the pets. JMHO

What twist? I am wondering if 1 in 10 will do.

U shot JB?

Bad boy!

It's like Thumper the rabbit said, “if you don't have anything nice to say, don't said anything at all”. I follow that wisdom as much as I can.

Shot a nice doe last year with 130gr 6.5 creedmoor, worked as expected.
Accuracy at 100 yds is .5" Not sure of the velocity.

3 years ago I put a 165 "Game Changer" Tipped Game King through a 9pt mulie at about 265 yards with a 300WM. MV was slightly over 3130 FPS and it grouped sub MOA. Hit was a double lung and he jumped, ran about 30yds and piled up.

About the same effect as Nosler BTs.

So they seem tougher than the 100 grain ProHunter or Gameking? Looking at some of the cartridges shooting them it would seem folks driving them pretty fast.

I have used the 175 TGK in 6.8W. So far shot 3 coyotes which blew big holes in and one very large for my area boar hog. Dropped the hog and shot through both shoulders and exited. Pretty stout bullet to do that. 180 hornandy IL and 162 IL out of 300/7mag respectively have not exited for me on similar shots. Tgk have a big hollow point but also a thick jacket along shank. Not tried in lighter weights but the heavy 270 seems pretty stout

I've posted this before, I shot a pronghorn a couple of years ago with one of the no-longer available .30 cal 125 gr TGK's, MV averaged 3227fps from a .308 (lotsa TAC). Antelope was about 150 yds, shot him through the ribs, got the topical death run. Examining the insides and the exit, my impression is that these are "tough" bullets; I wouldn't hesitate to use them in a magnum.

Sierra has changed these to make them better suited to the .300 Blackout, but they shoot really well in two .308's so I stocked up on blems of the originals when I was in Sedalia, probably have enough to last me the rest of my life.

If the other TGK's are constructed similarly, they are great hunting bullets.

Supposedly a harder core which is what keeps me from trying them for whitetails.

I have shot two deer and one hog with the 100gr 6mm GameChanger and it worked just fine from a 240 Weatherby.
All three shots were at or under 100 yards. All pass-through.
