Powder for reloading the ol' .270...

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.

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

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.

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

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

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.

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

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!
