300 win mag?

[knightrider]

Never owned one before, will the 180 grain soft point hold together under 100 yards or do I need a bonded or all copper for up close? Thanks

 

[DaveB]

You mean a lead cup and core bullet, in the Nosler world what used to be called a flat base spire point?
Like a core-lokt?

No, it won't hold together. It will however kill the deer dead.

I had a 40 yard shot with my 300 on a pretty hefty mule deer. 3 cow elk and 1 5x5 bull were killed also but distances were up in the 100+ range. The Muley was unhappy about being shot but not for long. Died in sight.

Two years ago I saw ears running up the gulch and swung around to get a shot. Doe came all the way up instead of the easier path and broke out 12 measured yards from me. As she swung her head to look at me I squeezed off a 3,000 FPS Accubond from my 30/06 A-Bolt.

There was no bullet remnant inside the deer. Nothing. A clean hole in a clean hole out. sliced the left half of the heart off from the right.

Accubonds and Partitions hold together. So do Barnes.

I have shot a truckload of deer with a 300 Win. Mag and it really depends on what bullet your talking about. A Sierra Gameking or Prohunter is thin jacket/soft lead bullet and will basically explode leaving small pieces of lead and copper scattered around inside, the older Nosler Balistic tips would fly apart when they hit also but I have been told they have reworked them so they stay together better now, a Remington Core-lokt is much more sturdy and I have found a few from deer shot head on within 50yds and most were mushroomed but did lose a good percent of their original weight. If you want to shoot deer most any of them will kill a deer out of a 300 win mag but if you want a decent exit hole without having to worry about small pieces of your bullet scattered around in the meat you will want to go with a bonded or all copper bullet.

Thanks.guys looks like I will be going Barnes , not a fan of chewing on lead.

I've shot several deer with my win mag using 180 TTSX, and they've all made reliable holes. I recovered one that went in a mature buck's shoulder and came to rest in its offside ham. It made a perfect mushroom that you'd expect.

I had a buck ,that weighed 209 lbs field dressed , in Ky come in under my stand one morning and I shot it straight down between the shoulder blades from 15 feet high,,with a 180 Nosler Bal Tip from a 300 RUM with enough RL25 for 3415 fps,,it broke the deers spine and there was enough pieces of bullet to grenade the heart and lungs that it all looked like jello,,but the bullet did not exit and the only piece I found was the solid base of the jacket in the spine,,

I was in the edge of a big field where I could see 700 yards and I shot that deer with the bbl sticking straight down through the floor of my Loggy climber,,

bullet performance was sketchy but the deer never took a step but it did soak up 4800 ft lbs energy at 15 feet,,

My experience has been that in most medium calibers, including magnums, that when using bonded or barnes solids to take shoulder shots when under 50 yards because vitals shots are like thru and thru with little expansion. That said, I would rather hunt with a bonded or barnes because they work well at all ranges. A 180 or 200 Accubond over a max load of RL22 is real deer poison in a 300WM

I've heard this theory before, but never understood or experienced it. It defies physics and logic, as the higher velocity and momentum causes more disruption and expansion. I have shot numerous deer with bonded bullets from under 50 to over 200yards, behind the shoulders or through them, with caliber from .270 Win - .300 Weatherby, and have yet to have a deer take another step, or a bullet not exit after good expansion.

 

[DaveB]

Accubond performance is something I was very concerned with. I had decades of Partition experience and was quite cautious moving into the Accubond arena. Here are early results and based on these I have made a near 100% conversion to Accubonds.

this is a pic of a small doe shot at roughly 85 yards with a 150 gr Accubond at 3,000 FPS.

The entrance wound is that little disturbed area of fur. The deer's backbone was dislocated and it died without a twitch. The exit would was not much larger.

The bullet drilled through the should blade. Wish I kept it-it wasn't a perfect round hole but it was not a smash through.



This buck I shot at a little over 100 yards same round. This one went about 30 yards and died with his legs folded up under him. Again, very little entrance wound, exit the same. incredible internal damage but not much bloodshot flesh.




This is a pic of the exit wound of a doe shot at 12 paced yards with the same round.



So, a close up shot with a 300 should probably perform pretty much the same.

 

[EastTNHunter]

Keep in mind that the Accubond is designed to expand readily at all velocities but shed between 40-60% of their weight with the shank drilling through. This is is the same performance design as the Partition and is what causes the similar entry and exit wound appearances.

 

[jlanecr500]

Most of the deer I kill are taken by 40 and 45 cal smokeless muzzleloader so that is the performance I am accustomed to. I only killed a few deer last year with hand loaded Accubonds in 30-06 and 300WM. All but one were shoulder shots with no tracking involved. Shot one doe double lung at about 40 yards (200 AB at 2950fps) who ran about 50 yards but ran up, over, and into some tough terrain. Lungs tend to.function at a reduced rate when a small hole is punched. Deer are resilient animals with a will to live. I like to eat them and hate to waste shoulder meat so this year I have some 210 bergers tuned up for those double lung shots. I built the 300wm in case I get an elk tag but just had to draw blood with it a couple times . The 30-06 has the same Criterion barrel that loves 165 AB's and 165 bergers. It kills just fine and is really all is needed. Ive never killed with a berger but plan to this year.

All in all, it really is hard to beat a good ole core loct or a hornady BTSP.

I think you are mistaken there. Isn't the Accubond supposed to retain well over 90% of it's weight compared to the Partition losing about half as you stated?

He is mostly correct. Both bullets are supposed to retain 65-70% of their original weight. Here it is straight from Noslers website. https://faq.nosler.com/index.php?sid=10 ... artlang=en

 

[Hunter 257W]

OK, I stand corrected if Nosler themselves state the same expected weight retention for both. I was just going by what Accubond users have told me about high weight retention. I've never used them since I have so many other controlled expansion bullets already on hand that need to be shot up before buying more. I don't know if this can be proven or not but I think the Partition often kills faster than a lot of bullets because the nose grenades doing a lot of damage then the base punches on through to do deep damage. I've had several deer drop without a step with behind the shoulder shots that would normally result in a 50 yard wild run 1st.

 

[EastTNHunter]

I thought that Nosler used to state a general 60% retention, but that sometimes varied by caliber and weight. Of course I could be misremembering, but I guess that they are going to a blanket 65-70% now if that was the case...

 

[DaveB]

I think the Nosler retention numbers reflect the propensity for people to sue one another. I have a few partitions I have recovered and % was in the 80's.


So far, every Accubond I have fired is bye bye baby.

 

[Hunter 257W]

80% for a Partition? That can't be right, Dave?? Around half the bullet is in the front end core. I've recovered several of the .257 115 and 120 grain Partitions and they are more like 50 - 60% retained weight. Don't read that as a negative slap against Partitions though as they are one of my favorite game bullets.

As far as "Bye Bye Baby" for the Accubond, you are meaning they went on through and you didn't recover them, right?

 

[DaveB]

Yep, through and through for every Accubond fired.

Most of the Partitions are the same. However, some of the Partitions I have recovered have a lead mushroom spread out across the copper petals. If that mushroom is gone, yeah, you get that 60-65% number. When it is present. you get the higher 80%.

I have a few someplace, will hunt them down and get some pics and scale them on my 10-10.

 

[Hunter 257W]

OK, they probably behave differently depending on caliber and of course what cartridge is firing them, i.e. velocity they impact the animal. I've only used the two .257 Partitions mentioned above and all of the ones I recovered totally shed the front lead core. I'm not doubting your word as I've seen that you keep good records and aren't prone to exaggeration!

 

[mike243]

I would look at some charts that show energy and drop and compare them,then shoot n see which 1 is the most accurate, then just shoot them and no matter how bad your bullet is if you try to save meat and not shoot spine/shoulder shots you will have runners.I have had less runners with my 243 than any other caliber as long as I didn't use a premium bullet that passed thru,the core locks out of my 300wm have broken into 3 similar size pieces and passed thru the heart/lungs of a 180lb 8pt shot at 75y broad sided.works for me and the accuracy is decent,

 

[DaveB]

257 I exaggerate all the time but on some stuff I tend to be careful. Now, why would I recall Nosler Partition percentages.......read on

I nailed a huge bull elk on the plains north and west of Craig Colorado. 30/06 corelokt 150 grain. Bull fell to his knees got up and ran like nothing was wrong. Shots ring out. 3 guys with 7 Mag put the bull down. I want my elk. they laughed, called a game warden. I lost my elk.

Ever since, 300 winmag in elk country. 180 partitions on top of Nosler Book Max load of IMR7828 at 3000 FPS. For first two cows, i took out front shoulders, no running anymore. Then next one I went behind the shoulder and turned out they were just as dead.

I shot a nice muley with my 300 and recovered the partition, first one. I was all eager to see the retention. It was low-no lead mushroom. Zapped a Calilfornia muley at around 200 yards quartering to me, got that one back, lead mushroom, retention was I recall 82%. I killed a deer in Perry county with a 150 gr partition and that one was also mushroomed. I recall this one clearly because Perry county had no deer at all and I took a LONG shot to get the one i did.

When hunting Elk or Mule deer out west or whitetails on big fields the 300 with 180 partitions is the medicine I choose to carry. To this day the picture of those 3 standing over my 6x6 monster haunts me.
