Any reason not to chose this bullet for all uses in my 7-08 and 270?

If they are accurate in your rifles then they should be great performers. Their reputation as performers is beyond reproach, accuracy maybe not.
Myself I've not found Partitions to be accurate in any of my rifles, my son has a 30/06 that shoots Partitions adequately but not great.

My old .270 shot well with the Nosler 140, averaging around 1.6 moa. That’s plenty for most hunting, don’t be fooled by the Internet warrior requirement for sub-moa-only loads. The reality is that most who claim sub-moa only have one or two groups that size...if any. An average is what matters, what you can count on, not the very best when the stars align. Either bullet will work the same, only 0.007” difference in diameter and the same construction. Find the right powder and go kill something!

They are fantastic. I have not had any trouble getting the 270 version to shoot well out of several 270Win rifles and a couple 270Wby rifles. Pretty easy to achieve MOA in a good rifle and in some cases quite a bit better. I have only loaded for a savage and 700 mtn in the 7-08. Both rifles shot the 140 into an inch or better. On game they are as advertised. A lot of penetration and good early expansion. You may get some bloodshot meat hitting shoulders at woods ranges, but you will still get plenty of penetration and an animal that knows it's just had it's ass kicked.

I have the 140's out of my 7-08 shooting right at an inch and I haven't worked on a load for the 140's in my 270 yet.

As far as accuracy goes and in bench style rifles I found partitions were best at the heavy end like 150 in 270, 160 in 7mm (7mm Rem) and 200 in 30 (300 Winchester) Those weights all shot extremely well.

I think it might relate to where the partition is located relative to the whole bullet. The heavy one have more shank behind the partition.

Well soon I will know if either of my 270's likes them.

Some research has suggested that impact velocities over 2600fps, along with good penetration, produced more dramatic kills and less follow-up. For the 270 and 7-08 that is easier to maintain with lighter bullets. The 130 grain bullets usually give 100fps more muzzle velocity and Nosler offers such in the Partition for the .270.

My wife's 270 shoots 1/2" groups with the Barnes 129gn LRX, and that would be a load of choice for her up to elk. With that accuracy it would work as an all-around load.

In addition, for deer-size game a person can go down to 110-120 grain in the monolithic bullets, e.g., Barnes and GSC.
She shoots a 110 gn TTSX at 3450fps for sub-MOA, too, which is lights-out on deer with full-penetration/exit. (In Africa she uses a 200gn GSC in 375Ruger at 3100fps.)

I run 140 Accubonds in my 2, 270 Wins at 2950 FPS. Manuals say the bullet can hit 3000fps.

I never needed 3000fps. I have had dramatic one shot kills with giant exit wounds after striking heavy bone on game up to 220 pounds live weight.

The Partition is considered strong in design than the Accubond. Go without fear.

My Remington model 7 with it's skinny 18 1/2 inch barrel will put three of the 140 gr. Partitions into just over an inch. At least four four 3 shot groups in a row. Now I let the barrel cool between shots. It actually shoots better with 140 gr. Ballistic Tips. Both of my 270's will break MOA with several loads. Nowadays even off the shelf rifles that don't cost much can beat MOA, a lot of them anyway.

My 270 Win loves the 140gr Accubonds.
I am not sure why one would chose the Partitions ahead of Accubonds as they should have similar performance.
Also, the Accubonds should be inherently more accurate than Partitions, but I stand corrected on that.
Perhaps others can comment.

I too prefer Accubonds to Partions. But, I can’t tell someone not to shoot Partions.

Both are two answers to the same problem. Both are right. I do happen to think the Accubond is more correct answer.

I came to the Accubond via the Ballistic Tip. I like the Ballstic Tip. I love the Accubond. Looking at it on paper, I did not see an advantage to the Partion. Others, maybe more, will have the opposite opinion. That is fine.

The bottom line 140 Grain Nosler (Partion or Accubond) in the 270 Win will serve you most well. If you want 3000 FPS you can obtain it with book loads. That is nice, but not needed.

Go forth and hunt.

Oh, if anyone wants to see a group with 140 grain, 270 Accubonds pm me email or iPhone number. I got you a 20 round group.

It is a little big bc I tried to draw a smiley face. I almost pulled it off.

I traded my way into a bunch of the .277 140 Partitions and there were 87 of the .284 variety. The 7MM is a 7-08 on a Rem model 7. The Partition is not as long as the Ballistic Tips or Accubonds so it will take up less case capacity. Otherwise I would use some of the many 160 grain Partitions and Accubonds I have in 7MM. I don't shoot past 250 yards where I hunt this rifle so a high BC bullet isn't needed. But what I need is a bullet that will penetrate deep and make a good hole. If the either of the two 270 rifles I have don't shoot it well I will use some of the 150 gr. Ballistic Tips I have. The 270 has plenty of room for long bullets.

I have rifles in various calibers that shoot the Partitions well, <3/4" CONSISTENTLY over time as long as I don't change the powder, seating, primer etc. When that happens I have to adjust one or two of the parameters...and others that spit them all over the place. I depends on the rifle, the shooter, the powder, accuracy requirements etc. I weigh/ogive measure/sort all the bullets in the box BEFORE beginning load development and bench prep the cases.

I shoot whatever bullet gives me the best accuracy and sub MOA is THE requirement....but I DON'T toss bullets that do worse...I just put the outliers in an other box for other uses. Out to ≈300 yds pretty much ANY bullet will handle even the largest game if it's placed correctly...so accuracy is a must BEFORE pulling the trigger.

If the Parts concern you, wanna throw them my way????

Good Hunting and Merry x-mas.

I just seated the 140 Partition on top of 46.0 grains of IMR4350 and primed with CCI 250 primers. COAL was a recommended 2.750 and instant good shooter in my 7-08. I haven't shot the rifle 40 times yet and that includes 16 factory loads. Anytime I get groups near an inch from a hunting rifle, especially with Partitions I'm good. When the weather nices up a bit I am going to start with my old Tang safety Ruger 77 270 and the same powder.

My only problem with partitions is the cost. from a 7mm 08 or a .270 just pick a bullet your rifle likes and get a good hit !
I like Speer hot cores. But Sierra and Hornady are fine too.
I like partitions and accubonds too , but they are not needed...

I agree that Partitons are a bit expensive but the trade I made got these for around $10/50 and I got some 400 bullets. I do think they shine when deep penetration is needed and in hunting thick areas. Not for bucking brush but to have the penetration needed for not so perfect presentations. I have been buying Ballistic Tips from Shootersproshop for a long time and feel these bullets are excellent also. I like Speer and Hornady bullets but after stocking up on various Ballistic Tips over the years I don't need to buy them anymore.

Im sure they will work on most animals, but I would prefer the heavy end of both for Moose and the big Alaskan bears...160 or 175 in the .284s and the 160 in the 270...That's my choice, what others use is not up to me....I don't believe in one bullet for all hunting. I like as many options as I can get. The .284s get the nod on this..130 gr. Speer to a 175 gr. Nosler covers a lot of acres.

For hunting Moose and big bears I would take a bigger gun that either a 7-08 or 270, starting with my 35 Whelen. I doubt I will ever hunt moose or bears larger than Black bears.

bears larger than Black bears

Considering now days a fair number of Black bears are killed that out weigh a lot of grizzlies.

(500 to 800+)

You might want to rethink that if size is the determining factor

You claim that most only have one or two groups Sub-moa or better is a crock of BS. If a modern bolt action with a decent scope from a bench won’t shoot Sub-moa I’m not interested in it unless I’m going too be hunting an area where only close shots are possible.
Ive shot less in the last few years than at any point in my life. If I can’t take any newer manufacture bolt action rifle I own and shoot sub-moa then it’s either going too get some tweeking or it’s going down the road.

Here is Nosler's explanation as to the difference between the Partition and the Accubond. It is cut and pasted from their FAQs.

What is the difference between the AccuBond® and Partition®?
The AccuBond® and Partition® are very similar in terminal performance, but they differ greatly in internal structure. The Partition® bullet is the original, controlled expansion, design created by John A. Nosler over 65 years ago. Long before the invention of bonding technology, the dual-core, partitioned jacket design of the Partition® bullet created the perfect blend of controlled expansion and deep penetration. The AccuBond® bullet was designed to mimic the on-game performance of the Partition® in a sleeker, more aerodynamic design by taking advantage of modern impact-extruded jacket design and bonding technology. Internally, where the Partition® features separate front and rear lead cores separated by an integral partition, the AccuBond® features a heavily tapered jacket and a single lead core which is permanently bonded to the jacket. Externally, the Partition® has a flat base and lead nose while the AccuBond® has a boat tailed base and a white polymer tip. Both bullets are designed to be general-purpose hunting bullets suitable for all game animals. Both bullets are designed to expand into consistent mushrooms while retaining 65-70% of their original weight with proven performance over a wide range of velocities and game. Partition® users will not see a gain by switching to AccuBond® unless their particular firearm shoots them more accurately.

If I needed an high BC boat tailed bullet I would pick the Accubond, the LR version. I will bet the Accubond is easier to make than the Partition.

That little statement goes a long way for understanding and comparing bullet choices.

Take 140 grains x .7 and you have a 98 grain final product. The penetration will be a partial factor of the momentum of that 98-grain projectile.

For comparison, let's give that 140-gn bullet a 2600 fps impact velocity, something produced by a 3000fps muzzle velocity at around 200 yards for reasonably sleek bullets. Momentum for penetration will be 98x2600 = 254,800 (grain-feet/s) units. (We can call that "25" for a comparison index.)

Now let's do a monometal bullet to see what happens, for example a 110-grain TTSX at 3400 fps muzzle in a 270W. These will regularly retain 105-grains of weight. Impact velocity at 200 yards is about 2900fps, resulting in a penetration momentum of 105x2900= 304,500 units. (That is "30" on our index.)

This is why monolithic companies like Barnes and GSC recommend going to a lighter-than-traditional bullet for similar-sized game. We have only been using the 110grain in 270 for the past three years. So far, three mule-deer and NO recovered bullets, all pass throughs, whether broadside or angled. That is not a lot of statistical evidence, but it is suggestive that the general approach to bullet choice is sound.

Personally, for all-around I would go a bit heavier, like the 129 grain LRX at 3100 fps. It's momentum units at 200 yard impacts would be 125x2750fps-impact = 343,700 (grain-fps) units. (Again, "34" on our index.) That bullet would be my all-around choice out to 500 yards where 10mph wind-drift is approaching 15-16 inches.

For deer-size game all of the premium bullets above would be fine. However, as angles and big bones on elk sizes come into play the monometal provides added insurance on penetration. Yet, be that as it may, the biggest criterion may be the old "accuracy" parameter: which bullet shoots best in a particular rifle. Flat-base, boattail, all-copper and lead-core can affect potential accuracy in any particular barrel. If a 1/2-3/4 MOA advantage can be found, that would override all of the above, IMO. The bullet can only do its work when it arrives on target.

Full disclosure: When and if I get to chase elk, I would prefer to carry something with a significantly larger diameter, e.g. 225gn at 2825 in .338" or a 200gnGSC at 3100fps in .375".

I have used a 130 NP in my 270's for untold years. Winchester brass, fed 215 primer with 61.5 gr RL22. +3200 FPS even in a 22" pipe. Never any signs of pressure in 3 different rifles.
Extremely accurate at 1/2" or less load in all my 270 rifles.
Outstanding deer load. Never had an hit that was not a pass through.
Good luck with your 140's.

I run 150g Partitions out of my BDL in 270 Win and have gotten just over 3000 fps for too many years to count. A more conservative load easily gets them to 2900 fps. Great bullet for the 270.

Ive found the Accubonds outstanding on elk and deer, as good as the partition..They have proven themselves super accurate in my rifles of various calibers, why then would they not? they are just a Balistic Tip with a bonded core, whats not to like about that...but the gun they are shot in will always be the deciding factor on accuracy..

I just got back from a deer hunt in Texas and used the 140 gr. partition in a Sako M85 in .270 WSM. The bullet worked great on a buck, 2 does, and 2 small (cull) aoudad. They were all 1-shot kills.

Still waiting for a Partibond or an Accutition to come out...

I know Swift makes the Aframe a bonded portion bullet for the 270.

I am not sure on weights, but that would be a tough bullet.
