I have also used the game king for years in my 30-06 (150 gr) and .270 (130). I have taken many deer with them. They are accurate and the deer die when hit. I went with game kings simply because I picked up a half box at a tag sale and found that my rifle liked them. They work for me but this is not to say another bullet would not work as well. I suspect that all modern hunting bullets work pretty well. Just choose the one that your rifle likes and you are ready to go. Don't agonize over the decision.

I used 180 grain GKs in my .300 WM for many years, but IMHO they expanded too quickly, i.e., I rarely got an exit hole (which I like because it leaves more blood on the ground).

Five years ago I switched to Accubonds and have never looked back.

Buddy of mine took out a grizzly in his pasture with a 250 grain game king from his back porch with his 340 Wby. One shot done deal. They work great. The Speer is also a great bullet.

I agree with you to a point BTM. I shot a bull moose a couple weeks ago with 180 gr GKs out of my 30-06. The first shot was a frontal shot and the second and third were broad side. The 2 broadside shots were complete pass throughs taking out the lungs. The first shot entered high in the chest and from what I could tell, fragmented, the core lodging in the left back strap, and from what I could tell, a large piece taking out the left lung, traveling down the body cavity slicing through the liver and diaphram and ripping open the stomach then exiting out the belly. It acted about like that mystery bullet that killed JFK!!

LOL!!! Never heard that term before. Thanks for the laugh.

Sierra Game Kings (and Pro Hunters; GK's are boat tails, PH's are flat-based versions) are notoriously accurate, and work just fine for deer, pronghorn all the way up through elk and moose. The trick to Game Kings (and Pro Hunters) are to keep impact velocities under 3,000 fps. Above that speed, as someone else pointed out, bullets tend to come apart, shed their cores, limiting penetration. As a rule of thumb, if you're shooting a magnum caliber, premiums are never a bad idea. For standard caliber, they aren't necessary. All in all, I suppose it boils down to what your rifle prefers and shoots best with.

Exactly what j23 said! Very well stated!!

I've used the 165 gr SBT for years. Never had a problem with it.

I've used 165 gr GKs in .30-06 and 300 gr GKs in .375. Will they kill an animal? Absolutely.

At typical impact velocities between 2500-2700 fps I've never NOT had one disintegrate. They're accurate and they do kill, but I prefer not picking fragments of jackets and cores from my venison.

I've only shot one whitetail @ a little over 60yds w/ a 243 and a 100g SGK. Didn't recover the bullet, results were about a 40yd death run and one dead deer.
Now ive read more than a few times where folks seem to feel that the pro-hunter is a tougher bullet than the gameking........any thoughts on that?
