I have a rem 7400 270win.I'm loading 130gr bullets and would like to know what your favorite powders are?

the "powder" for the 270 is of course 4831. I use 59 grains of 4831 pushing a 130 hornaday interbond and the groups tend to average about .80 out of my rem 700. I prolly could do much better if I played with bullet seating and such, maybe if I truly floated the barrel and beded the action but for me that is shooting about as good as I can ask for, so don't fix it if it anin't broke

IMR 4831.

54 grains of imr 4350 behind a 130 grain sierra prohunter bullet for fun from my rem. mtn. rifle. When deer and elk season opens, I'll use a 130 grain nosler partition instead.

I would use H-414 52 to 54 grs with a 130gr bullet, and a win large rifle, or CCI-250 magnum primer

I agree with the other two posters on imr 4831.

I haven't played very much with my 270 but I've used all the above mentioned powders. If velocity isn't a huge issue then H-414 was very consistent and accurate. My powder of choice so far is RL-22 for both accuracy and velocity with 130 gr Hornadys, it also seems to do an admirable job with 140 gr. Accubonds. My buddy has the same rifle as I do and he sees some promise in H-4350.

I loaded extensively for the 270 win with 4831 until RL-22 came out. 4831 is very good but I think that RL-22 is even better. However if I was loading for a Semi-Auto I would contact the manufacturer and see if there were any slow powder - port Pressure issues as there are in a Garand.
My 2 current loads are a 140 accubond with 60grs of RL-22 and 61grs of RL-22 with a Barnes 130gr TSX. Both loads are very warm and may be to hot in your rifle so work up slowly. Both shoot 1/2 minute out to 300yds in 2 different rifles, a Mato and a Finnlite........DJ

I still have 40 lbs of the old Army surplus 4831, sometimes referred to as 4350 data powder...Its the same 4831 that Jack O'connor used...You can get 61 grs of this stuff in the .270 case and make it sing with any 130 gr. or 150 gr. bullet.....When I run out, and thats not likely at my age I will use 58 grs. of H4831 for a couple of hundrec FPS less velocity....

As usual, I am the odd ball in life.

I do different than most everyone else with the 270. I load it with Nosler Ballistic Tips, 140 and 150s being my preference.

Since I know they open a lot better at under 2700 fps MV then above, I reload mine to have a MV of 2650 fps.

The powder I use is 44 grains of H 380, with a standard Large Rifle Primer. It is still flat shooting out to 300 yds which is more than needed for game smaller than Elk.

Disassembling a Winchester factory load, they use W 760 which is the same as H 414.

Although I carry a 6.5 x 55 or a 7 x57 more often, I load my 270 to be in the same performance neighborhood. Accuracy tightens up dramatically in mine at this velocity.

Cheers and good shooting.

HOLD IT!
Isn't the Rem.7400 a semi-auto?
Isn't 4831 too slow for this one?

My current 270, a left hand 700, LSS likes the Nosler 140gr BT over H4831

Easy question. Reloder 22, hands down.

First off, everyone on here is telling you how to load a bolt, not a 7400. I load the exact thing for a 270 with a 130 sierra. Here is what i have found. One, everyone of these critters have a personallity all thier own. What cycles well in one and is accurate, might not cycle at all in another.

Tryed 4064, from 45gr to 48gr, and wouldn't cycle reliably. 47gr showed promise, but after 3 rounds, no good.

Then tried Varget, same as 4064. Not a huge surprise.

Re22, too slow. H1000, don't even think about it.

Then tried IMR4350. Cycled like a champ from 52gr to 56 gr, I believe. 54gr puts up 1.5" groups very consistently. Won't jam in cold or hot weather. Shoots 2980fps. Now this goes against the grain with advise from Sierra and most other semi shooters. They say 4350 is too slow. But the way I figure, most factory hunting premium ammo, uses simular powder to get the velocity numbers like this. And this gun has ait factory for most of its 2000 round life.

This worked for me. But might not work for you. Might take alot of work. If it jams, you can adjust seating, and loads. I would go for 4831 to start, and see how that does.

I have had very good success with h4831 in a 22" barrel. I tried IMR 4350 thinking a bit faster burning powder would give me better speed but I was surprised to find that I was two hundred fps slower than what the book said. My load is 60gr H4831 130 nosler partition and fed210 primer I get 3000fps with the 22" barrel.

60 gr H4831 or RL 22 with a 130 gr ...

59 gr RL22 behind a 130 gr Barnes X. - Dan

I am relatively new to reloading and have tried a few combinations of bullets & powders.

My .270 A-bolts likes the 51 gr of H4350 shooting 150 gr of Nosler BT (CCI 200 primer). I get 3/4" grouping out of 6 shots.

While the Ballistic tips are much more accurate than the spire point bullets, I have reservations on using them for big game hunting. There are just too many stories out there about the BT failing. Because of this reason, I will be developing a new load using the Hornady Interbounds in the up coming months.

Cheers!

Dosen't everyone load the 270 Winchester? LOL!!!
One of my 270's likes 4350 powder with a sierra 130 grain flatbase, 54 to 56 grains. The other likes IMR 4831, and a 130 Ballistic tip. RL22 works ok as well. The key here is, what does your rifle like as to charge weight and bullet style. Some of the guys have given you some good opinions etc, but working up the loads is the only way to tell the story.

I tried some H-1000 and had jamming problems.I guess i'll have to try a few different and see what my 7400 likes.Now i have a lb of h-1000 sitting doing nothing.

guys, all you slow powder loads are for bolts don't work so great in a 7400. Maybe a bar, but the 7400, you have to find a powder to cycle correctly first, then with that small window of operation, you adjust seating depth for accuracy.

I don't know all about autos, but my Ruger 77 270 does great with 53.5 IMR 4350, Win LR primer behind a 130gr speer grand slam. This is actually the first and only combination that I tried in this gun and I was happy enough with it to call it good. Never been through a chrony with it but it shoots about an inch give or take group at 100.

I have acheived my best accuracy w/ H4831 in the 270 win. I would not load them very hot in that auto loader.

Good Luck!
