    Everyone usually mentions IMR4831 or IMR4350 right away. I prefer an old favorite: Winchester 760. I love the way Winchester's ball powders meter.

    Under some Sierra 140gr. Game King bullets, the 760 load produced 100-yard four-shot groups of .79 and .88 inches today. And these groups were out of a semi-automatic; a Belgian/Portuguese Browning BAR. My stash of 760 is old enough that it's packaged in metal cans.

    The Sierra Game Kings are not "premium" bullets but they have never failed me as far as accuracy and performance on game are concerned. I've killed a bunch of whitetails with them.

    If you're having trouble working up a good .270 load, you might want to give 760 a try.

    I've always used 4350 for 270.I have some 760. I'll have to try that. Never tried it in my 270. Ive always used 760 in my 243

    Same here, I’ve never tried 760 but it looks like that may change. :thumbup:

    After loading up batches of 6.5 Swede I tried some Reloader 22 with 140 gr Nosler Ballistic Tips and 150 gr Hornady SST’s in the .270. These loads both shot very well in my Mauser M-96 American.

    Stay safe.

    There's a very good reason that IMR 4831 is so popular.

    worked up loads with the 145Eld-x over Hybrid100v, and 4451. Used 4831 with 150s for a friend of mine.
    Haven't tried 760 yet, if I get another .270 I will.... actually I could probably use it in something i shoot lol

    I have used a lot of H414 AKA WW760. It meters so well I see no use for IMR4350 any longer.

    My rifle tends to prefer those heavier bullets. It shoots sub-MOA groups with the factory Federal Premium load of 150gr. Partitions.

    Other powders may offer similar performance, but I don't think you can beat the way those ball powders meter.

    When I started reloading in 1983 for my Winchester 30-30, I used Winchester 748. Then, I used it for my .223. Later on, I had other calibers to load for and I experimented with other powders. I remember the first time I ran some extruded powder through my RCBS Uniflow measure... ugh! I hated working with it.

    I was a huge IMR4831 fan in my .270, but my latest load development was done with H4831SC.

    Obtained the accuracy and velocity I was looking for and added some better temperature stability. Since I load .270 strictly as a hunting round, with 50-100 rds a year for practice, I don't mind weighing and trickling charges.

    I'm sure not disputing the excellent performance of IMR4831 or other powders in the .270. I'm just happy that I found performance that impressed me with a powder that I can simply and easily meter through the powder measure.

    And, to be honest, the performance is sort of moot for me. Where I hunt in the Adirondacks of NY, my shooting is mostly at short ranges. I could easily get by using that old 30-30 I mentioned. But it sure is nice knowing your rifle is capable of whatever you might need it to do!

    My In-Laws live in New Hampshire near Lake Winnepasaukee (sp?). I learned when I first visited them that seeing anything more than 40-50 yards away is almost impossible, that New England hardwood forest is some damn think stuff! The .30-30, .35 Rem, .444, .45-70, etc. are all perfect calibers for that kind of dense-woods hunting :thumbup:.

    Stay safe.

    I never tried 760 in a .270. Might be because I don't have one......but the most accurate load I found for my .243win was Win760. Even better than my IMR4350 loads. I was surprised.....I had thought the 4350 was king in .243. Then again that was 40 years ago.;)

    I am having pretty good luck with my 270 and IMR 4350. 1" groups at 100yds, factory Ruger Hawkeye stainless.

    The new Hodgdon 6.5 Stabil powder is looking good for .270 Winchester ....I

    The standby IMR 4831 and Reloder 22 are both good powders....

    When I first started loading the 270 I had a hot load of IMR-4895 pushing a 130 gr Nosler Solid-Base that would cloverleaf 3 shots. Don't know how fast they went but 1 more grain on a hot day made the bolt sticky. I've learned a lot since them and found that slower powders worked better.
