I'm looking for data using RL26 in a T3 (24" barrel) 7mm Rem Mag with 162 ELDX and 160 NAB. Anyone have experience with this combo?

Is the Speer bullet a substitute for the Accubond?

Ran some RE 26 in the 26" factory 7 Rem Mag with 160 Accubonds today.

New Fed Brass, Rem 9 1/2 Mag Primers, .040 off the lands at 3.325" COAL.

RE26 VEL
64gr - 2820
65gr - 2873
66gr - 2912
67gr - 2955
67.5gr - 2974

I only shot two shots of each... and accuracy showed a lot of promise. I stopped at 67.5 because that's all I had loaded up, extraction was smooth and primers at 67.5 look no different from those at 64 grains.... I think there's still room to run. I'll load a few more up to 69 or so and see if/where we top out.

Thank you for this posting, co-incidentally I am working on similar loads. Reliable data for RL26 is not easy to find right now. Earlier this year I worked up a load with RL 25 and 162 ELD-X. The best result for my rifle (Browning X-bolt 26") was
69.0gr of RL 25 .018 off the lands at 3031fps. Of course, RL25 and RL26 aren't the same thing. but they seem to be pretty close in burn rate.

Dogshooter, you are making me feel like I'm on the right track because I just loaded a ladder from 64.0gr. to 68.5gr. of RL26 with accubond 160gr.

It may be a week or so before I can get to the range, but if it's still relevent after I do I will post my results.

My 8 twist Brux likes 180 gr. VLDs over RL-25.

I'm anxious to see what RL-26 will do with the 175 NPT and 180 VLD.

One guy on Reloadersnest was running 69 gr. RL-26 with CCI 250's, pushing a 160 gr. HPBT at 3,090 fps. He wrote that 73 gr. Retumbo gave the same velocity. I was thinking RL-26 was slower than Retumbo. According to that, probably not. These are not certified loads, so proceed accordingly.

Shot more of them today....

67.5 - 2981
68 - 3011
68.5 - 3038
69 - 3057 ** Sticky Lift **

At 68.5 the recoil got nocitably more sporty, and blast seemed to border on obnoxious. At 69 extraction was a little sticky... but this gun gets a little sticky on occasion with some factory loads. I think a guy could land anywhere between 3000 and 3100 if he leaned on RE26 a little.... just like he could with RE25, 7828, H1000, etc.

In the end, I settled on the 67.5 grain load, the extra 50fps isn't worth the additional strain on brass (and shooter). I ran it out to 560 today, drops were dead nuts using the advertised .531 BC, and 2 MOA sized rocks were in big trouble this afternoon. I'll load up the rest of the box, and I may or may not tinker with the seating depth a little.... but for now, I think I'm gonna call it good and worry about finding a bull and a big rutted-up mule deer buck to put in front of it this fall.

The test rig: 26" Stainless 700 in an MPI stock, 3-9 Leupold Mark AR (Duplex) in low Talleys (bedded)... 8lb 2oz all up...

Checking up on RL-26, it may actually be faster than RL-25.

Alliant claim it falls somewhere between RL-22 and RL-33. That's a lot of territory, big gap.

I guess we'll sort it out over time.

I loaded two each 162 ELDX and 160 NAB at 68, 68.5, and 69 grains. I'll try to get to them this afternoon. All bullets loaded to 3.290".

I know two shots each isn't much, but it should give me a better idea. Magnetospeed Sport.

160 AB results, speed only:

68 gr 3007, second cartridge wouldn't chamber. Hmmm.

68.5 gr, 3039, 3042, ave 3040.5, ES 3

69 gr 3056, 3060, ave 3058, ES 4

The primers looked great for 68 and 68.5, a touch flowy with 69. I'm going to load some 68.5 and chase accuracy. Temp is around 78 but I'm n the shade.

ELDX next.

162 ELDX results, speed only:

68 gr 3036, 3030, ave 3033, ES 6

68.5 gr, 3058, 3077, ave 3067, ES 19 (dang)

69 gr 3092, 3108, ave 3100, ES 16

Primers look good, a friend with much more experience is coming over, I'll have him examine the primers. I know primers are a poor indicator of pressure. No bolt lift or extraction issues at all.

My best load for 7MM mag was or is 73.0gr of Retumbo with 160gr Accubond. 3042fps in my Vanguard. Next best load with same Hornady cases and federal 215M primers is Norma
MRP at 67gr. for 3046fps. third best load is RL26 68.5 gr at 3106fps Winchester cases and WLRM primers. I got lower SD with WLRM primers and more FPS. Accuracy was
third best. A little over a inch at 100 yards the other 2 were under a inch.

I would say based on Alliants data [above] you are in good shape.

I have some 168 grain Accubond bullets. 26" barrel Rem 700.

I have quite a bit of Re: 26, 3 lb H1000, ~ 5 lb H4831sc.
+ faster powders.

Other bullets on hand - 162 gr Horn & 150 gr Partitions & 150 gr combined tech. 154 gr Hornady Interlicks, & some no-name seconds 160 gr bullets - has bullets 284 160 spitz by on the box but the bullets are not boat tails and the do weigh 160 gr

My son-in-law wants something more power than his 270.

I offered other cartridges but he wants the 7mm.

My point of view is if more power is requested, there's little reason to go lower than 150 grain.

So, I'm thinking Re 26 and first the Accubond then the 162 grain Horn. Then the 150 grain bullets.

Questions
No. 1 : those Accubonds are quite long, stability issues??
No. 2 : Re 26 best of my powders for 150 to 168 grain?

Thanks for the above information and the links and any positive replies.

Additional info 160 grain bullet - 68 grains Re 26 - Fed 215 primers - ok in my Ruger 77, a little warm in this 700.

Range results:

I ran a seating depth test, 162 ELDX, 69.0 gr., three shots each at 6 different OAL. I got .539" at 2.644", no pressure signs.

I loaded an identical test for my brother, he shot .3" at 2.665".

Not bad.

My long throated 7Mag seems to like RL26 behind a 175 partition. Just finished loading up a batch for WY Elk/Mule Deer.

66gr. but of course my rig is long throated so I'd work up. that's pushing about 3014fps in my rig.

That's pretty fast for a 175 NPT, maybe that long throat turns it into a "mini Wby"... wink

Nosler claims 2970 with RL22, so based on data from Aliant and Nosler it seemed within range, especially overlapping the Whizzum speeds with a 175 being slightly faster. Primers are looking good as well.

I have a long-throat 7MM Rem Mag that shoots 175 g. partitions at close to 3,000 fps with IMR7828SSC. My stock of IMR7828 is nearly gone and happen to have several pounds of RL26, so this thread is of great interest to me.

Reloder 26 has been the powder I have been using the most lately. The initial PR confused the burning rate question but for small to medium size cases 243 to 30-06 it is very close to MRP and 7828. In larger cases WSM and belted magnums it is closer to R25. In my 270 WSM the charge weight is the same for R25 and 26 but usually R25 is slower. Any 160-180 grain 7mm load is a stone cold killer at close to 3000 fps. I almost am willing to give up my 300 mags. but not quite ready to do that yet. Getting the same or higher velocity as my old H870 loads and the cleaner burning and no copper fowling is a big plus. Formerly cleaned every 20 rounds or so with H870 and now I think I could go a 100 with R26.

Have your tried Dyna Bore Coat?

If not, I'm thinking you'd get even more rounds between cleaning with a DBC treated barrel, and the clean up would be easier and faster.

Pharm, is this with your Tikka t3x superlite? I need to start working up some good loads for my new rifle. I don't know much about the ELDX, is that a match grade bullet, or are you going to hunt with it??? Thanks buddy..

My brother has a Superlite, I have a T3. The ELDX is a hunting bullet, the ELDM is a match bullet.

I got 2840 out of the 180 ELD in my 26" factory 700 using 65 grains of RE26.... I loaded up three at a pretty standard 180 VLD load to see if they'd stabilize in the factory tube..... they certainly did, and shot under 3/4".

Gonna load up a dozen more and stretch them out a little.

It dose...I`ve both cartridges, the 7 RM is throated to match the free bore in my Wby. Both have 26 inch tubes..7RM is factory take off bought from a "fire" member. Using the 162 ELD-M and RL-25, the cronie says 3190fps. Velocity matches balistic drop numbers to 600. The Wby is 25fps slower with the same powder charge and a PAC-NOR 9 twist barrel.
