Nosler Partition Stories

The Partition is a great bullet. The concept of a 2 part bullet with a partition wasn't original with John Nosler, the German H Mantle preceded it by a bit.

In practice they tend to shed 1/3 to half of their weight and usually exit. Final expanded diameters tend to be right around 100%. All in all it's a good compromise between fast killing and the closest thing you're likely to find to a guarantee against total bullet blow up. The soft frangible front does the real work of blasting big wound channels and the expanded base is along for insurance against inadequate penetration which occasionally happens with total blow-up. You'd make a bigger hole if you blew the whole thing up, but compromises sometimes have to be made.

You know what else sheds 1/3 to 1/2 of its weight and ends up at 100% expansion while exiting most the time? A Hornady Interlock. Or a Remington Core-Loct. Or whatever they shove in blue box Federal. Or; horror of horrors whatever standard factory ammo is on sale. Those makers of factory ammo aren't as stupid as some think.

What you really get with a Partition is the ability to say "all of the time" instead of "most of the time".

hmantel is the best bullet for leopard and lion but and this is a big but you need to know what they re doing ...
 
You generally don't recover them. Really, when you consider the concept is 1951 tech, really still the bullet most are measured against.

Meant to retain 50-60% original weight, front of partition peels back and the harder rear core punches the mushroom through.

My problems with the partition are first price. My 375 rum likes 260 partitions, had one box of 300gr. X reload price $150/50. Secondly, the exposed tip is prone to deformation. Thirdly, while I've yet to find a rifle that won't shoot them decent, I've never found them super accurate. A little above or below MOA is normal. Not worth it to fuss and try for 《1/2 moa. It's a hunting bullet.

My problem with them is the price, they are incredibly expensive bullets, particularly for being 1951 technology. TSX/TTSX are cheaper(which saying something) so I usually just buy those instead.

No question the Partitions work though, which is doubtless why they are so wildly popular in spite of the price.

1948 for the partition ... created first for the 300hh after a failure bullet on hunt on moose. i spoke with the grandson nosler that loved the accudomb still prefer the plain jane partition most of the time.
 
I have been using Nosler Partitions since 1965. I have killed over 100 head of big game with them.
They are a very reliable bullet. Most exit... I have recovered about 24% of Partitions shot at game.
As for accuracy...the older, bronze jacketed design with the groove in the jacket were not particularly
accurate, in my experience.

The revamped design that is common now has been much more accurate, and easier to develop an
accurate load. In a couple of my rifles, they are the most accurate bullet I use. From the 60 grain .224
partition to the 260 grain .375, all work similarly.

There are many very good bullets out there today, but that venerable partition is still the bullet I
compare all others to. Dave. Recovered Partitions below.[1-TTSX, and 3 bonded bullets also]

In my .338WinMag my favourite bullet has been the 225gr NP. Shot a lot of big bull moose with it.

I had 1 big bull that my buddy called in, shot it at 40 yards, all broadside shots, and all 4 went right through. Left 4 really cool little 'vapor trails' of blood and lung tissue on all 4 shots. Oddly enough those are the only NPs I've ever shot into moose that I did not recover.

I've also played with the 200gr NP in .30-06. Whacked a nice bull broadside 150yd (2) shots. Both bullets were recovered.

The Nosler Accubond is a better bullet than the Partition.

Dollar for dollar you cannot beat the simple Hornady Inlerlock, and if I could ever figure out where to buy them I'd order a mess of Remington Corelokts in all calibers.

I use Hornady Interlocks in more calibers than any other bullets.

My favourite Premium bullet is the Woodleigh Weldcore. I love that Woodleigh actually designs them for cartridge/caliber specific velocities.

This may be...I have shot several animals with the Accubonds, with complete success, but I will not be able to shoot enough animals to prove this.

I do not concern myself with cost, since how many bullets does one usually shoot at game? I would qualify the above with the caveat that the Hornady Interlock be flat based, and limited to speeds under 3000 fps. The Cor-Lokt is a good C&C bullet, but high velocity is it's nemesis also.

My favourite Premium bullet is the Woodleigh Weldcore. I love that Woodleigh actually designs them for cartridge/caliber specific velocities.

The Woodleigh is a well-designed [and constructed] bullet, but can be very finicky to get to shoot well. None of my 8mm rifles will shoot the 220 Weldcore acceptably, and my 303 absolutely hates the 174 grain for some reason. Dave.
 
Old technology for the day they were competent they have fallen behind even there own brothers the accubond bullet is far superior higher bc better design as far as controlled expansion much more accurate
 
I have been working with a couple of other bullets lately. The Norma ORYX, and the Swift A-Frame and Scirocco II.
The penny-pinchers will object to the cost, but so far, these are proving to be very good premium bullets.

I shot a nice bull Elk 2 years ago with my 8mm Rem Mag and the 220 A-Frame. Basically DRT.

This years Bull Elk was with a 196 Grain ORYX from my 325 WSM. Dead within 10 yards.

I've been using Nosler bullets for reloading since 1982, they have never failed me. However, they have become ridiculously expensive. My son is the only one who uses the partition bullets, 85 grain for his 240 Weatherby, we usually utilize accubonds and ballistic tips. Slowly, I have been accumulating Sierra Gamechanger for my two newly rebarreled rifles, a third one being built in the near future. Because of cost, I'm slowly weaning myself off of Nosler.
 
Love seeing that I’m not the only one that appreciates Partition. For a bullet to be around as long as it has and is still continually considered THE bullet to compare others too, is hats off to Mr. Nosler!

They seem to be hit and miss on availability. I’ve easily acquired a collection by looking at the smaller mom & pop shops around the country. Prices seem to be fair for a reliable bullet.

Accuracy wise I’ve found that they do respond to switching primers and powders more than other bullets and do like to be pushed a bit.

I stumbled upon the partition attributes merely by accident. I was looking for a short bullet the would perform reliably at all velocities and suit the 284 win in my Borden Apline Magnum action and not push the bullet into the case past the neck/shoulder junction, and the 140gr Partitions did just that!

Let’s keep the stories rolling!!

Swifts are great bullets in that they always do exactly the same thing. In my experience they are the best buffalo bullet. For lesser game there are faster killing options, but for those that value penetration highly while still wanting impacts that make a mono look like 22 LR they are as good as it gets. I haven't bought any for awhile; but when .458 partitions hit 6 bucks apiece and Swift A-frames were 80 bucks for 50 I wrote them off. Winchester factory loads with Partitions were cheaper than 25 Partition component bullets.

I honestly think that Nosler is trying to price their slower selling Partitions out the market in favour of the Accu-bond
 
I just checked my Partition stock out of curiosity;
6mm: 85, 95 & 100
.257: 100, 115 & 120
6.5mm: 100, 125, 140
7mm: 140, 150, 160 & 175
.308: 150, 165, 180, 180PP, 200 & 220
8mm: 200. Canadian Tire had a blowout sale on these a while back [$35.00 per box of 50] I bought all there was.
Think I'm OK for a bit.

30-06 and 200 gr are one of the best combo for most of the na game.
 
I’ e used them lots in the past in my 30-06s factory ammo, then moved away from them to use either TSX, TTSX or GMX(I as really happy with the first 2). Then I got a 9.3 and decided that the Partiton would be more adequate for the velocity so I started loading them and got my moose last year with my first reloads! Medium Yukon Alaska moose at 106m somewhat frontal shot, entering the left side between shoulder and neck, reaching the heart, punching a rib at the front on the opposite side finishing its trip in the far leg deep in the muscle! That moose didn’t even move a hair and dropped on the spot!
But I also loaded some Swift Aframe that are similar in design but different in construction(the front end is bonded) and that is what I will use in two weeks for bisons!
 
I can understand the reputation they have gained, but have a hard time understanding why someone would use lead when there are non-toxic substitutes available that do the job. What really shocked me was a study I read on lead in processed game meat. Wouldn't want to eat it or feed it to my family.
Edit: if you're Eagleye's age, you probably have nothing to worry about!

woodleigh are great bullets and i do like them in the 9.3s.
