Nosler partition speed

[Girlsfishtoo]

Loading for a 270 win and shooting a 150gr nosler partition, great grouping with only a muzzle velocity of 2770 fps. Is this a good speed for the bullet to perform well on deer and moose. Thanks.

That will kill either real dead..should be relatively gentle on the shoulder as well......care to mention the load? ..I made up some for my son's bull moose last year...........Harold

Sure, I'm loading a federal large rifle primer, 55.5 grains of h4831, 150 gr nosler partition. I actually went above book max to 57.0 grains and the speed did not change so I went back to the 55.5 grains and a COAL of 3.320. It gave me a 3/4 4 shot group at 90 yards.

Did you shoot that across a chrony or using book velocity? That's quick for a 150 out of a .270win

Yeah I used my crony, so it says with that load I'm getting 2770 fps muzzle velocity, but the book says I should be getting 2905 with 55.0, but it's accurate

Yes, it groups well now go hunting...
Oh yeah and those partitions will punch through anything from moose to mouse!

[bulletman]

I use 56-H 4831 SC in my .270 Win. with 150 Nosler ABLR'S. Very accurate!

[bobinthesky]

2770 is a good speed for the 150 grain bullet. If it groups well then I'd leave it alone, another hundred feet per second isn't going to make a lot of difference.

Of course, you can always experiment some more in the name of science....

Don't take the velocities listed in loading manuals too seriously, it is common for the actual velocities in a given rifle to vary by 100fps or more. Due to variances in chamber/barrel dimensions, and lot to lot variances in components, the velocity of a given load will vary from manual to manual as well.

If it shoots well and you are comfortable with the recoil, I would go hunting with it and not look back. Trust me, a deer won't be able to duck that 2770 fps bullet.

[Girlsfishtoo]

Ok thanks everyone for the input. Never shot the partition, always shot the tsx but the partitions caught my eye for my 270.

Partitions are one of the oldest premium bullets. Over the decades, many companies have somewhat copied and made something similar. In spite of that, they do remain as one of the best bullets around.

Shoot that load with confidence.
Partition's are the golden standard in bullet performance. Everybody compares bullets against the standard set by the Partition.

You traded up for sure you will like the way they perform

Shot in the dark are you shooting a rifle with a 22" barrel by chance? Load data is usually published with a 24" test barrel. Could explain the difference.

Also 2770 fps will be more than adequate for anything you mentioned. Happy hunting.

Totally agree.

That's good you are further ahead than most! Too many folks don't use empirical evidence as information.

I agree the Partition is a top notch, premium bullet. Only thing to watch for in the 150 Partition for the 270 specifically is punch throughs with no expansion. I have had partitions in 30 calibre, 7mm, 338 and 375 all work absolutely excellent. 150 grain in the 270 didn't open up properly on deer, bear or moose. Got a 270 hole in, 270 hole out. Check over your first deer real close and examine the wound channel. I went back to Interlocks in the 270.

[Girlsfishtoo]

Yeah it's a 24 inch barrel. Punching though without expansion? Yikes!, that's why I was kinda concerned about velocity.

Dean2 what was your muzzle velocity?

The partition is my first choice if available.

About 2850 fps. 24" barrel. Very similar load to yours 58 grains 4831 (Gov surplus before it was tagged H or IMR but made by Hodgdon), WW brass and a CCI 250 mag primer. I don't think the velocity is the problem. Most of the other Calibre and weight partitions I used were around 2800 fps and they expanded perfectly. I don't know whether I got a couple of boxes of 150s with too thick a jacket, poorly made or whatever. Only ever happened with the 270. That is why I say pay attention on the first thing you shoot.

Nosler makes great stuff so I would bet they will have fixed any issues the 270 bullets used to have. My problems with their bullet was almost 30 years ago and I haven't hunted with a 270 in at least 25 years, not since moving up to the .284 calibre cartridges, so never retried Nosler Partitions in one. Will be interested to hear how these new ones do on game.

i hear people say that all the time but i was not very impressed with their penetration in the last animal i shot with them.

the penetration was no different than an a-max. the front of the bullet evaporated and the button ended up not going very far at all (never even exited on a deer)

this was a 165 out of a 30-06. so then i kind of thought to myself "if i'm not going to exit why not just cause as much damage as possible"

so now i'm working up a load for the eld-x

There musta been a drop of water in your barrel.

I have run these bullets in multiple calibres and only found one taken inside the hide from a distant shot that was disformed but killed. Distance, less velocity etc tributes to this but 300 yards or less your partitions will mushroom at 270 velocities. You got a great pet load for your rifle so go out and hunt. You might retrieve a bullet from a game animal but I dought it as pass through are the norm.

[Pathfinder76]

There is nothing on this continent that that load at that velocity will not kill.

Here is a bit of a read you might be interested in. I believe her load consists of the 150gr partition.

Or that condensation trapped by electrical tape!

[Tactical Lever]

Never heard of one not opening or not penetrating. Kind of the way it was designed, was with a soft point that would completely get peeled off if driven too fast and hitting something hard close up. With the 60% surviving no matter what.

I guess with enough examples there will be a few anomalous performances.

Back in the days before we had a gazillion component bullet choices, I loaded and hunted either with Partitions or Grand Slam bullets and never experienced a failure of any type. Mind you, I never disect an animal either to do an autopsy to find out how much a bullet weighs after the fact.

I should add that knowing of a lady who not only has such passion for hunting but also rolls her own ammunition is cooler than cool.
