    Does anyone have any real word experience with their performance on game. Will be shooting Whitetail, Axis and possibly something as large as a cow Elk. They shoot very well in my 280 Ackley with RE 23 powder. My go to load on these small southern whitetails a 140 grain ballistic tip. Thanks for any input on these.

    Put one of these slugs in where they burn thier fuel at any reasonable distance and you will be filling your tags in no time.

    I certainly understand that a 140 grain bullet in a .284 caliber rifle will be more than adequate for most large game at medium distance. Seems I'm wired in a way that makes me shoot the most efficient bullet for caliber. Meaning basically heavier for caliber bullets. So if I'm shooting a 140 bullet, it'd be from a .264 or .277 rifle. Again a .284 caliber rifle is a great caliber to launch a 140 and harvest game with. I guess I need to buy some 140s for a few of my 7mm cal rifles and rewire my process. I'm the same with all caliber rifles I own. Maybe the exception is varmint rifles where I will shoot the lighter weights in .224 or .244 at times on the smallest critters at closer ranges. I do have game king experience on deer with a .270. They perform very well for me and being I shoot them from a BAR, they are very accurate for an auto loader. Don't think I've had a white tail deer go 5 steps after being hit with one. Haven't used them in several years as newer bullets have filled their place on my bench.

    I shoot them in my 7mm-08. I have made shots on whitetail out to 250yds. they still opened up well doing lots of damage but still a pass thru. I haven't recovered one yet to see what they look like expanded. It is one hell of a killing machine. I wouldn't hesitate to shoot an elk cow with one.

    Elk are big critters, that bullet is designed for medium game.
    If everything is perfect, it might work on elk. Personally, I would opt for something a bit less frangiable designed for smashing through heavy bones.
    Partitions and bonded bullets for heavy critters works for me.

    Thanks guys for the replys, looks like I may opt for the 160 BTSP Gamekings. These also shot very well in my rifle. Couldn't get the Partions to shoot as accurately as I would like. I built this rifle with a 10 twist, the long bonded bullets just will not stabilize.

    Maybe give the 160 HPBT #1925 a try, its a tougher bullet. I imagine that 280 Ackley will have them going fast enough for Sierra to call it “Magnum” velocity.

    Did you try the 160 Nosler AB ? You didn't mention which 160 bonded didn't stabilize, the AB has worked in 1-10
    If not since you use the 140 NBT I would try the 140 AB, they are tough for a 140 and should ("should") shoot similar to the 140 NBT.

    Sorry I am a little late to the party. I have had great results with the 160 gr HPBT Game King and the 160 BTSP. If my memory serves me correct they were running 3065 fps out of my 7 Mag. They are both tougher than people give them credit for. The bullet that was the most surprising in my experience is the 154 gr Hornady. Not quite as accurate as the Sierra but it's terminal performance was fantastic on several whitetails ( I know, you are shooting elk, just throwing it in.).

    Regarding the Partition I was shooting the 150 gr and their accuracy was on par with the Hornady. On my 250 yard range I was consistently shooting 3" 250 yard 5 round groups with the Partitions and Hornadys, The Sierras stayed closer to 2-1/2". The rifle was a Tang Safety Ruger 77 made the first year they put laminate stocks on them. It had been bedded and I put a Timney trigger in it. Nothing fancy, just a factory rifle. My next new barrel will be another 7 Mag. Great caliber, a 160 gr 7 mm bullet has physics on it's side. No need for expensive projectiles to make it work.

    Good call,
    I have never seen a partition hang with an Nosler AB or SGK for small groups, however thay will hold minute of elk for 300-400 yards in my experience if your case has the boiler room.
    I will add, I have never seen DRT (Dead Right There) on elk as consistantly as I have with Nosler Partitions. They just work!

    Drop Port, I’ve tried both of the Accubonds and they just didn’t shoot very well in this rifle.

    I'm a firm believer in using enough gun. But, elk are not hard to kill. Put the round in the chest, not the shoulder and just about anything will get the job done. I have killed 4 or 5 elk with a 7mmBR and 130gr bullets, a few of them were dead in their tracks.

    gamekings are great bullets--put more emphasis on where you put it, rather than what kinda slug you are using

    I have to disagree.
    I have witnessed several good shots made on cow elk with frangible bullets and the cow was on the move! One was a shot from a .243 with a SGK, another was from a 7-08 with a SGK. Both hit the boiler room and shredded at the ribs. The youngster with the .243 hit the cow three times in a matter of 2 hours and you could have covered the three round group with a dollar bill. The last shot got a fragment into the heart and he harvested his first elk.
    Bullets are designed for a specific purpose, medium game are not near as solid as large heavy game. Elk can be BIG.
    Please, do not hear me say Sierra makes poor bullets. Quite the opposite is true, they are masters at their craft. Light weight SGK bullets are not designed for heavy game. Keep in mind, all bullets have a range of velocities they are optimized for. I have observed solid hits on elk at stupid yardages and the bullet did not perform as the hunter would have liked because the bullet was traveling too slowly. If you have questions, ask them about their bullets and what your plans are, they will be happy to make a recommendation.

    I asked sierra about a better bullet for elk for the 7mmBR, they told me it was light, but they don't make anything bigger for pistol velocities. In fact they don't make that bullet anymore.

    If you want to say that elk are hard to kill and BIG, why start with a 243? You did not mention what weight bullet in the 243, so I am guessing it was on the lighter side. My experience with Sierra bullets is that they do not stand up to bone well, regardless of whether it is whitetails, or elk. A rib exploding a bullet, must be a VERY lightly constructed bullet, the ribs are only about 1/2" thick or less and about 1.25" wide, hardly heavy bone.
    I shoot elk mostly with a bow, but I have killed them with a 270 winchester with sierra 130's, 7mmBR with 130's at 2200fps or so, 405 winchester with slow cast bullet, 45-70 with slow cast bullet, 475 wildey 400gr going maybe 1000fps, 300wsm, and probably some others that I don't recall. I have never had one go any distance after being shot.
    The 270 with 130's put one through the chest, it exited leaving a 1" exit hole, the next round went within 2 inches of the first, he never moved other than falling over, that was at 40 yards. One of the 7mmBR elk was at 360 yards, it went maybe 60 yards, the bullet exited. The farthest an elk traveled after being hit with the 7BR was about 100 yards, it was a 200 yard shot that removed the top of the heart, I recovered the poor performing bullet. It was bent in the shape of a banana. The 405 punched perfectly through the heart, it went maybe 50 yards.
    I have killed many elk myself and have "guided" many friends, with a total of dead elk probably around 60 or 70. I have only seen one elk take multiple "good" hits and keep going. That was with a 338.
    An average cow rocky mountain elk is going to go about 400 to 450, an average raghorn maybe 500 to 550. It takes an older bull to get over the 700 mark, the stories of 1000 pound bulls are just that, bull, unless you are talking about 380 class bulls and up.
    I will take a 270 for elk anytime. I have a moose hunt next week, I would use the 270 for that, but I'm taking a lever gun.

    No offense intended, just offering up my opinion.
