Hey guys-

I decided to try out some 150 partitions in my .270. I have Noslers data, but I'm looking for your experience with accurate loads for it. What do you use? I've always used H4831 with 130s with excellent results. What else is worth trying?

Thanks in advance

Gib

In my opinion, H-4831 goes w/ 150s even better than 130s (and that's a tough combo to beat). 58 Gr H-4831 w/ 150 Nosler and Winchester brass is pretty standard "max" load. I've had extremely good luck with this load (and 150 Hornady SP) in my .270s, but as always use caution and load to max, don't start there.

Some of the newer manuals list a grain or 2 less as max. It should be noted that brass can make a difference. For example, Rem brass generally takes a grain or 2 less than Win.

Good Luck,

Lou

I meant "work up to max" not "load to max"

I shot my first deer with a Nosler 150g Partition, Oh too many years ago. Back then I read too much Jack O'Connor and had visions of Elk loads(he was alive back then). I begged my Uncle to load me some up with 4831. He only had IMR-4831, so I got 56g of IMR-4831 with the 150g Partition (hot) but it worked in my gun.

These days I prefer the 130g Partition with 54g of H-414 but I still load the 150 partition the same as years ago and haven't been able to beat it.

As always start low & work up.

I have had great luck with 58 grs. of H4831 and the 150 Noslers in my 270s...

I just picked a pre 64 up in 270 std. grade and thats the load I will shoot in it. It will be fun using it again.

I have not used the .270 in many years but I shot a lot of big game with one some years ago. Guess I'm regressing back to my roots..I know I have as I usually hunt deer with my 25-35,,,,

I think you have selected a great combination. I have settled on 150 gr. Nosler Partitions, H4831 in Winchester brass as my standard big game load for years. I have used this load on deer, bear and moose and have not had any problems. I think it was Bob Hagel who noted in his book entitled "Practical Hunting Loads for North America" (or a title similar to this) that one should not overlook the 150 gr. when testing the 270 as it provides some additional punch with minimal difference in trajectory to the more popular 130 grainer for practical hunting purposes.

I use 57 gr. H4831 in my bolt rifle and it produces one and a quarter inch (1 1/4") 3 shot groups at 200 yards. It is slightly below max however with this accuracy l leave well enough alone.

Good luck and have a safe hunting season.

Quoting from memory here, so verify against reloading manuals: 58 grs of RL22 has worked well for me with the combination .270 Win/150 grs NP. Although this load did not produce the "promised" 3K fps in my rifle, the load has been accurate enough for my hunting purposes.

As usual, work up from below.

I've had very excellent accuracy with 52grs. H4350 and 150Noslers, how about under 1 moa out to 200yds. but that's about max, so work your way up from 50grs.in half grain increments, Win. primers, and Brass, Jay

MY best 150-grain Nosler Partition load is 53.5 grains of IMR 4350, WW cases, Fed. 210 primers. This load has been very accurate in my two Mann./Schoen. 20" bbl, 1/9" twist carbines. It gives 2880 FPS in a 20" barrel.....

H4831 has long been considered to be the ideal powder for the .270 with bullets from 130 to 150 grains. IMR4831 would usually be considered to be the second best choice. I think that H4350 and IMR4350 may sometimes give a slight accuracy edge over the 4831s, but at a bit lower velocity.

Recently I'm finding that RL22 may be an even better powder for the 270, superior to the 4831s.

. . . . don't overlook IMR 7828. It is just very slightly slower -- by about a grain in most applications -- to the old original surplus 4831 that made the .270 famous.

Gib, try working up a load with a Ramshot powder and let me know what you think. maybe something like TAC or Big Boy? Good luck.

Try Imr 7828 very accurate, like Stonecreek suggested and maybe give the new Hornady -Interbonds a try. You will be surprized at the combination.

Some time ago, I decided to try 150gr partitions in my custom Ruger .270, so I loaded up some Win brass with WLR primers and 59 grains of H4831.

First group, 5 shots in .36" at 100 yards. Second group, 5 shots in .33" at 100 yards. 2924fps. Can't beat it with a stick.

Might be hot in your gun--work up from below.

If there is a perfect match between any cartridge and any powder, its the 270 and H or IMR 4831 from 130 through 160 grain bullets.

Gib--for years I used H4831 and IMR 4350-excellent choices for sure. Alas, when R22 showed up I went to that and have not looked back--great accuracy and the best fps I've found with any powder. It may be something to tap into.

From my Winchester pre-'64 FW .270 I get between 2,900 and 3,000 fps with 57.5 grs. H-4831 and the Nosler 150 partition.

Generally that is a fine load for elk up to about 250 yards. Beyond that range, I HAVE had a few problems with it. Did a few years of "control" shooting in eastern Oregon, shooting 4-8 elk cows per year. Because of the purposes of those hunts shots were often at distances I'd rather not shoot living animals at. (That's why I voluntarily quit doing it.)

Anyway, at distances of, say, 400-600 yards or more, velocity is low enough that an elk hit in upper leg or shoulder sometimes had a nice clean hole of exactly bullet diameter in the bone, but no signs of bullet expansion. Luckily shooting conditions were such that none escaped wounded, but most had to be shot several times. After two years of that, I swore off the .270 with Nosler 150 Partitions for longer range elk, and returned to using the .300 Wby cartridge with 200 gr. Partitions, and the 7x65R with RWS H-Mantles. Both kill rather more surely in my experience.

Still, this is clearly anecdotal, and is just my experience. Only reason I posted it is to remind shooters to look at more than just whether the animal dies. How quickly and how humanely are also important.

If .270 w/150 Noslers work for your hunting conditions, fine, but do some autopsies and decide for yourself whether it is really adequate for the circumstances in which you use it. If not, you know what to do...

Fireform,

That's the exact same combination I came up with and very close to the same velocity. This with a 22" barreled Remington 700 CLassic. I'm taking it to NFLD next week to try that load on Woodland Caribou.

Anyone loading these with Viht N160? I appreciate some info.
