I never once suggested I wanted to go faster, the loads I had very well might be way too hot but the sd was single digits and it was a three shot clover leaf at 100 yards. I want a very accurate load and do want my velocity to remain up at 2950 or 3000 fps since I do hunt elk and big mulies and only need to have decent velocity so I still have good ballistics and penetration ( stopping power if you will ) at distances up to 500 yards. I'm not looking for a speed demon since I also load 130 grain sst for this rifle and they are moving at 3075, if I need speed I can get it from this load.

Ok, I'm willing to try some Alliant powder. I have no load data for RL 26, the Hornady book is showing RL 17, 19 and 22, all of which are available at local shops. I have researched RL 23 and 26 but load info for these is harder to find. Has anyone tried RL 17 or 19 or 22? If so did it perform well or should I be going for 23 or 26 instead? And if anyone has a load they're using for 145 ELD X and RL 23 or 26 at least it would give me an idea of what guys are using and the performance they are getting. Thanks for all your comments so far. Do you have Mule Deer's article on new powders in the .270Win? He used RL-26 (among many others) in those tests and it performed impressively with the 150 grain.

I have had and shot several 270 Winchester rifles over the last 40+ years. Back in the day IMR4350 or 4831 were my go to powders for a 130 gr bullet. That being said, I was only getting around 2900 FPS out of them. A chrono will either make you real happy or real sad, but in all my years of shooting, I never have heard anyone brag about how fast they missed what they were shooting at.
R26 has turned one of my 270's into an honest 3070 FPS shooter with 150 gr bullets! Heck years ago I could not get that speed with 130's. At 2900 FPS I was shooting sub .5" groups when I did my part and I have never seen a 130 bounce off anything I was trying to kill, whitetail, mule deer, speed goats, etc.
I may not be smart but I can lift heavy objects
I have a shotgun so I have no need for a 30-06.....

58.5 of rl22 seems to be the sweet spot for me and the 145 Eldx. I could push it a bit harder but don’t see the point considering everything is very healthy.

Ok, I got my hands on some RL 26, I'm ready to take the leap from Hodgdon lol. I also got some brand spanking new Winchester cases, yeah I know, Lapua and Norma blah blah blah. Anyways I will be trying the RL 26 in Win cases, CCI Br2 primer pushing 145 ELDX. I have heard a few times 60 grains but still don't have any published data on starting and ending loads for this powder/bullet combination. I only have data from Hornady book with RL 22, AND data from Alliant powder website with RL 26 but not with this same ELDX bullet. Anymore info on this configuration is appreciated. Thanks for all the great info so far folks.

60 grains seems to be the magic number. As always, approach with caution.
I am continually astounded at how quickly people make up their minds on little evidence or none at all.

I can’t get ahold of any RL26 locally so stuck with H4831 Getting 2950ish with 58 grains and the 145eld in a Fieldcraft.
Yup.

Wierd, I looked back in my notes and at 58 gr of 4831sc I was at 3075, and with 58 gr reg 4831 I was at 3020. These higher velocities was why I started questioning my pressures in the first place. And that's with a 22 inch barrel doo I should not be faster. Anyways gonna give this RL 26 a try in the next couple days and see what I come up with, I'll let you all know what I find out once I've chronographed the loads.

Thanks for all your comments so far. Alliant publishes a data manual every year online. Just download it. Hodgdon does a printed manual every year, but cartridges come and go in those, but their online data covers it all. I found data for StaBall 6.5 in the .243, which isn't in the 2020 book. Anytime you substitute components you introduce variables that may result in issues like you're having. Best to stay as close to the data as you can while you're learning. Never exceed it, and stop adding powder when you get to the published max velocity, regardless of the charge level you're at. Check your case length, and measure the O.D. of the necks on your loaded rounds. EDIT: Just checked my Hornady book, and you've substituted primers, brass, and powder (4831SC uses H4831 data, but is not identical and IMO should at least be treated as a different lot). Not a bit surprised that you have some issues. Did you work up to where you are, or pick a level under max? Primer choice alone can affect pressures by thousands of psi. Every loading manual has articles on the various aspects of the process and how they affect your results. Read them if you haven't, and re-read them if you have.

Yes, I have looked at my Hornady book AND checked the downloadable data online from both Hornady and Alliant AMD neither of them show load data forthe configuration of Hornady Eldx 145 using RL 26 for a 270. Apparently this must be some kind of unicorn load since there is no publishe info from the manufacturers, I hope that means it is a great load since they are keeping it a secret. I have now emailed both Hornady and Alliant asking for any info they could offer. As soon as I hear from them I will start loading a test up from possibly 56 to 60 grains looking sty all your posts and and depending on what the manufacturers suggest. Thanks for all the recommendations and I'll be posting what I find out from my testing as soon as I have the info.

It's really not all that hard.

60.5gr RL 26, Fed 210, Winchester case, 3.210 oal. The rule of thumb two yrs ago when most of us started stuffing rl26 into the 270 case. You cannot get enough rl26 into that case to hurt anything. Far as his load of H4831 I would switch primers, and try it again..

Then STFU. The rest of your statement is superflous bullshit with no real bearing on this discussion other than to massage your own ego. Suckin' on my titties like you wanted me.

Mainly I was trying to explain the pressure issue you have with loads from the Hornady manual. Again, no surprise that you have them because your components are different, except the bullet. I expect that the reason there's no data for your bullets is that RL26 probably came out after the Hornady manual was written, and the ELDX wasn't commonly in use when Alliant worked up their data. Takes time for companies to catch up with this stuff and testing is expensive and time consuming, so they have to pick and choose from available components. Alliant data goes from 130gr straight to 150gr, skipping the middle weights. Absent actual data, I would go with loads for a bullet a bit heavier, and work up from there, matching the other components as much as possible. BTW Mule Deer's .270 article in Handloader 322 lists 60gr of RL26 with your bullet, in Winchester brass with CCI200 primers, the same load he used with 150gr Nosler ABLRs. To the best of my knowledge, BR2 primers are the same as the 200s, just made by the most skilled workers.

I like R26...for cold er temps/hunting. My wonderful load of 60gr/160 NP in a previous 22" .270 went 2930fps. It was around .90 inch "until". Until the temps reached 80 deg here and my groups opened up to 2 1/2" or more and hard bolt lift/ejection marks on case head. Bummer. I have some R26 ( 2# ) I'm trying to trade for either R17 or R23 around here. Dang hazmat fees really put a damper on me ordering a couple pounds. It might be worth it if I needed an 8# jug of anything!!!!

Ouch!
I worked up my load for the 160s with now-discontinued W780, and have enough for my "duration". My load is mild, presumably about 2700fps, and has killed several deer, very much dead pretty damn quick, for my crew and myself. Great bullet, and the somewhat blunt profile bothers me not a bit.

[quote=Jim_Knight] I like R26...for cold er temps/hunting. [/quote Same experience for me which is a shame but could still work for winter time hunting. I would recommend getting R16 instead of R17 as you might have a repeat experience with R17 due to hot weather spikes. R16 is almost a flat liner across all normal temperatures and it loads very similar to R17 just not as dense.

Ok so I loaded up some 145 ELDX into new never fired Win cases with CCI Br2 primers with a cartridge overall length of 3.350. I started my loads at 57.4 grains of RL 26 and stopped at 60.6, knowing that a few of you had said around 60 grains is the magic number. By the way I tried to get loaf info from both Hornady and Alliant and both said they had not done testing on this bullet powder combo so they gave me no info. I have both emails if you are interested in seeing them. Lol. So street loading the rounds I went to test them. This is what I got from my basically new Magnetospeed chrono, temp outside was about 65F. Remember I shoot a Winchester XPR with a 22 inch barrel.
57.4 3035
57.6 3003
57.8 3026
58.0 3044
58.2 3050
58.4 3070
And that's where I stopped testing since primers were a bit flat and noticed harder bolt lift and on final round noticed a ejector mark on case.
So I really don't know how I'm getting these speeds and pressures with these loads. I am going to drop my starting gains to 56 and if I can get a decent node around 2975 for without pressure problems I will be very happy. I just don't understand how everyone else says 60 or what they are shooting without any pressure problems, the only thing I can come up with is possibly a shorter headspace in my rifle. Or could it be there primer? Anyways like I said I'll try to lighten that load up a bit more and try the chronograph again.
