As by popular demand I am gonna beef up my load for moose hunting and go from my 140gr Accubond load to a 150gr Nosler Partition load in 270win. I need to know if anyone has a Nosler reloading manual and would like to help me out with a starting load or data for the 150gr partitions, needed is COL and powder quantities of IMR4350.

Have you tried the IMR site or emailed them?

The latest Nosler manual I have is the third one, and it doesn't list IMR-4350.
Nosler used Winchester brass, Federal 210M primers, and H4350 to work up loads for all three 150-grain bullets in the 270.
They list 48 grains as a starting charge, with a velocity of 2530 fps, and a max of 52 grains @ 2780fps.
IMHO, that sounds awfully anemic for the .270 and H4350, but that is what is listed.
(And my manual doesn't list an OAL...)

Forget about O.A.L.

Its determined by your rifle anyways.

A moose is big and you can get close to them easily.

I would shoot that bullet seated on 51 grains to start.

My rifle wont let me go above 54 grains.

But 53.0 grains is pretty warm also.

At 55.0 grains I blew a primer so dont go that high with a 150 grainer!!!


IMR4350 is a good powder in a .270 win.
I prefer it in the 06' also.
Your brass will tell you when to stop!


Goodluck Don

I agree with Don in Idaho on col, also the choice of 4350 would not be my first choice H-4831 or AA-3100 has always been my first and formost choices in my 270 and many others I have talked with that reload.

The 150 NP would also be my choice for the moose and if your going to use 4350 52.5 grs would be max load for that powder with a starting load of 47.0grs

Use H4831 in the .270, probably 59 grains in Winchester cases with 140 grain bullet for about 3000 fps. H4831 is the classic .270 powder for the .270 and there is a reason why. It shoots well in damn near all of them. 4350 is just a bit too fast to work right.

4th edition of Nosler manual is same as the 3rd:

they only list H4350, not IMR4350.

Hodgdon 26th edition lists for 150 gr bullet:
IMR4350
start--48.0

max--51.0

270 and 150 grain bullet for MOOSE!

That sounds a bit under-powered to me, but I don't hunt moose. Elk calibers here are 300 Win. Mag. and 45/70 Govt. (Roosevelt Elk)

Seems like a moose would require something larger, and heavier. But then the military is hunting insurgents with a 223.

It is a bit small, but my guide in BC had killed a truckload of them with the .270 and a 160 grain bullet, he didn't say what bullet he used.

H-4831 is indeed the Classic powder in the 270 Win.

You might give RL-22 a try. I've used it for the last 15 years with excellent results. Good velocity and accuracy. Start around 54grs. and work up. You should get a little better than 2900' per sec in a 22" barrel and a little better than 3,000 per sec in a 24" barrel.

Nosler No. 5 shows H-4350 as the most accurate powder tested with 150 gr bullets in the .270 Win. Starting load 48.0 gr up to max of 52.0 gr. with a Winchester case and Federal 210 primer. Their max load, (also listed as most accurate) showed a velocity of 2782 fps out of a 24" Shilen barrel. Nosler showed best velocities with H-4831 max load 55.0 gr and Reloder 22 max load 56.5 gr both going just over 2900 fps. Other good powders to try would be Accurate 3100 and Vihtavuori N-165. Vihtavuori N-165 is excellent in my .270WSM with the 140 gr Accubond, both for accuracy and velocity.

If you want to use that IMR 4350, here is the reloading data from the Nosler Reloading Manual Number One.

150 grains Nosler Partition - .270 Winchester

IMR 4350

Max. -- 53.0 grains -- 2889 F.P.S.
51.0 grains -- 2786 F.P.S.
49.0 grains -- 2695 - F.P.S. -- *

* = Most Accuarate Load Tested.

Rifle- Custom Mauser
Barrel Length - 26"

Remington 9 1/2 Primers.

Good luck on your hunt!

For three years in Alaska, I used nothing but a .270 carbine with 150-grain Nosler Partition bullets, for ALL Alaskan game except the great bears (which I left stricktly unmolested!!)

My load was 53.5 grains of IMR 4350 in WW cases with Federal 210 primers. From my 20", 1/9" twist Mannlicher-Schoenauer barrel, this was a 1.25MOA (for 5-shots) load, and the MV was 2800 FPS. You can use 51 grains as a starting load. Quit increasing at the point of best accuracy, or signs of getting too hot, whichever hhappens first! If pressures seem to be going too high, drop back 5%.

(There was a doctor's wife in Faibanks at that time-mid-1960's, before the Endangered Species Act-who killed a polar bear with a 150-grain Nosler Partition bullet. I don't know what the powder charge was.)

I seat my bullets 1/10" short of the rifling origin, or 1/10" under magazine length, whichever is shorter.

Your guide in BC can shoot all the moose he likes with his .270,I consider it awfully light!I live in BC too,and I use an 8MM Rem Mag,shooting 220 A-Frames at almost 3000fps,and I've still had to wait for them to decide that they're dead after 1 or 2 through the boiler room.That's not to say that a properly placed .270 bullet won't kill a moose(of course it will!),but it would certainly not be my calibre of choice,especially since BC moose share their habitat with some large and sometimes aggressive grizzlies!My $.02-Monashee

ranger66 did you know nosler makes a 160 semi-spitzer, it also a great bullet,for your powder choice i think imr 4350 is not slow enough,better powders were mentioned above reloader-22 hodgdons 4831,don't over look barnes bullets ,or speers - (tbbc) trophy bonded bear claws, non of these will let you down,don't know if you reload at all. moose are hugh animals thats a given tastey too!!!,lots of times they will stand after a shot or 2 sometimes the caliber doesn't matter if its lite or heavy 270 or 460 magnum, great advice as usual ....regards and good luck..jjmp

Lent my 270 Win to a friend last year. He was using 140gr Sierra SBT, 59grs H 4831, Rem 9 1/2M primer. Vel for this load is 2875 ft/sec. He bagged a good sized moose at 90 yards, one shot. Word to the wise about moose.. They are a reletively easy animal to kill, but hit him wrong and he turns to STEEL

I can't help but chime in here as the 270 is probably my favorite cal.

I also agree that there are better calibers for the job, but I'll assume you either have your mind made up on the 270 or you do not have a bigger caliber.

This is what I'd do:

First, I wouldn't want to shoot a moose with a 270/150 combo beyond 250 yards, so accuracy for me is second to velocity so long as you still get reasonable groups.

I'd find the maximum charge in 3-4 different powders and which ever one shoots the highest velocity is the one I'd use. If you can group into 6" at 250 yards, have at it. A moose has a huge vital window.

With the 150 grainer, I'd want to juice that sucker as fast as I can. While I also agree that the 4831s are excellent 270 powders, I'd strongly recommend you check Re22 for that velocity factor....and while you're at it, you might seriously consider using a magnum primer.
