Powders for 270win

[270WinDude]

I was wanting rl16 but it's always out around here so that leaves easy access to rl15 and rl19. I'm wanting to try one of those for my lighter bullets and see what happens. Any opinions on which one might be better by chance? To a lesser extent I'm also curious about 4064 and varget...

I'm currently keeping/using:
h4831sc for 135match.
RL22 for 140vld and classic hunter
imr4350 for 130s also for the above 140s and 135s

I've used accurate 4350 also but it didn't quite pan out except for my 110vmax which all powders seem to shoot acceptable out of.

Funny and ironic at the same time.
Getting ready to load some 130 ballistic tips with 56gr of Rl19. Rl17 proved to be best for this particular rifle. I'm loading the runner up charge for sighting in a new scope. Saving the Rl17 to load after sight in and chrono work as I can't find Rl17 anywhere.

What else is funny is that RL17 never occurred to me nor do I think I've ever seen it. I think I'm just going to break down and do 19 for now and if the bug hits me to do a faster burn rate I'll just steal some of my step dads 4064 which he'll never use. I don't think we have to worry too much about temperature variation anyway which is mostly what drew me to 16.

If you can find some Rl17 up north.
I'm running 53.7 gr behind the same 130 bt.
Using wlrp to lite the fire. I'll have velocities after next range trip.
I found this load using components I had but wasn't using in other calibers.

I've had excellent results with IMR 4064 behind 110 Gr bullets.

I'm old school...I use IMR 4350 in my 270loads...Mike in ct

 

[Murray Brook]

Tried many of the slow burners in my 270 Win and always got the best results with IMR 4831 with bullets from 130-150 grs.

My dad loaded 45 gr of imr 4064 begins a 130 Speer in Winchester brass for years and had no complaints. I think it’s a great powder for the light bullets.

I just recently started reloading for it and am using 56gr h4831 behind a 140 game king in Nosler brass.

IMR 4350 and 130 Sierra Spitzers - expect tight groups, flat trajectory, and one shot kills.

 

[Dusty Stevens]

I think imr4831 is still the only powder for a 270

 

[Bayou]

I also run 4064...

I have a pair of 270s that are very different load-wise. I have a Ruger M77 MarkII .270 with skeleton stock that likes Nosler 150 BT's with a full case of H1000 and an old (old enough that it's gotten the nickname "Pops") Savage 110 flat back that likes 130 grain SSTs and a moderately warm load of H4831.

Not the same but similar; my Ruger M77 tang safety likes 120 gr Sierra HPBT's with 7828. Would have thought it would like a faster powder, but there you go.

I don't usually go with anything faster than IMR4831 in a 30-06 case unless using very light bullets. I keep solid stock of H4831, IMR7828, RL22, and H1000 for 30-06-sized cases. But that's just me.

I switched up and did a complete start over of my thoughts of the 270WW, after not having one in my stable for about a dozen years.

I got away from 130's. Looked around and settled on the 150SST, I have had good luck with them in other calibers in the past,ymmv.
More studying. I and a couple of buddies decided on R26.
I will say it is not a benchrest powder right off the get go. But it exceeds my thoughts on a hunting load. I get excellent speed and great accuracy. It really shines at 3-400. That is further than I actually like to call "hunting" distance. But,depending on where and what your hunting that may be an average shot.

( I made a couple of Creedmoor shooters have a big cup of stfu a while back with this rig)

My go to 270 Win load for 130gr Sierra GameKing is 55 gr IMR 4350, Win brass, and CCI 200 primers .010" off. 1/2 moa in two of my hunting rifles (Win Mod 70 SG and Ruger Hawkeye). My Rem Sendero prefers H4831.

I have been old school on the 270 with 130g what evers for a long time. Then Saw my nephew killing some large deer and hogs with the 110g Tipped tripple shock...blew me away how they hit the ground on the spot. Some of his shots were on the longer side shooting across fields.

So, I get out my old Ruger SS with the boat paddle stock, and start working with R#17 and the 110's, jumping the bullet .050. Boy, did I hit a home run around 57g with a 215 doing right at 3400 fps shooting 5/8" groups. Out of boredom, I next tried the Win 760, 58g with a 9 1/2 shot 1/2" groups at 3375 fps. I shot deer and hogs, they flopped on the spot.

On one morning, I had a heavy 8 pointer standing behind a 8" pine tree. I shot through the tree and killed the buck on the spot.

Next, I thought that I would try the 110g Sierra and 110g hornady HP for varmints, they shot extremely well (1/2") in the Ruger with the same 760 load and with the same bullet impact with all three bullets.

I don't think that I will ever shoot a bullet heavier than the 110g TTSX again. I sight in at 200 yards, and by chance, the cross hair of the leupold 3.5x10 has a thin center and thicker part. Just where the thicker part starts is a perfect zero for the 110! Stick a fork in me, I am done! The trajectory of the 110 makes me feel like I am shooting a 220 Swift!

I will be selling off a bunch of these 130-140g bullets.

I have not confirmed this in my own 270's, but I have some friends that are claiming right around 3000fps with 150 grain bullets and Reloder 26. I also read several posts and articles claiming the same thing a few months after it came out. I don't know where they were getting their powder though.....I was unable to get any until several months after it was announced.
If this proves to be true it is strange. I have used it in the 280AI and the 30-06AI and found it to be fantastic, but only with heavier bullets. As I understand it in the 270 with 130 grain bullets R26 shows no advantage velocity wise. I saw the same thing in the 280 and 30-06AI's. In fact, unless the bullets were at least up around 170 grains I saw no advantage.
I honestly don't know if I have ever put anything down the barrel of a 270 that wasn't 130 grains. My father-in-law bought out an old gunshop 22 years ago and there was 5 or 6 boxes of 130 grain Remington bronze point bullets. I am just this year getting to where I am running out of these.

I have to whole heartedly agree......

I keep hearing about this with the 110s and deer. It hasn't been hard for me to get them to shoot accurately either but will keep on trying to see what my limits are.

Hmm interesting. Thanks, defiantly worth me looking into. If anything one can not have too much variety in powder just in case.

Check out alliants Rl16, they are claiming 3200+ with 130's

I shoot AA3100 in my 25-06. I did a fair amount of development before I decided on the powder bullet combo. It was advertised as a high speed and low pressure powder for SOME cartridges and bullet weights.
Found it odd as it usually doesn't go that way. Forward a few years and they dropped it. I was told this and that powder was the same, BS, because I had used it in my load work up.
Loaded up all of what I had and that should last me a long time.
Forward a bit more lil'gun,hybrid100v,8208 just to name a few came on the scene and data showed high or higher velocities with average or lower pressure. Reloader 26 came up and it did for the 270 what the 3100 did for the 25-06. So after the initial 1lb jug was used up an 8lb keg was procured.
Read the data. Maybe my 270 has a fast barrel, along with two other guys I know. Started at a mid range load and worked up running over the chrono. Load work started in early fall and it was cool. We shot some in the spring and summer with no issues, speeds were higher but saw no pressure signs. We ran up to and over book max. Never saw pressure signs, but there was no noticeable gain either, so I am at book max for the 150.

Light bullets and speed. That gets into the discussion that more often than not turns into an argument over time of flight verses weight for bucking the wind.

I played with both in various calibers in years past, inside with the weight myself. The R26 and 150 combo gave me both speed and weight. I tell ya this thing thinks it's a 7mag now.
