Its no good in .280. Or in any other caliber, apart from the one I have got. You need to sell your R26 to me :)
bahahaha, coulda sold you a tub- but its on its way to cuz Bob in chch.Quote:

@Brian's got it out at his place. Its a Rem - I will check it out. Not sure if he used it or not.Quote:

anyone else tried 162 withe re26 in 280?
Not yet, switched from RL22 to N560 and got an extra 100 fps (now 2980 fps with the old 162 AMAXs) Have a couple of bottles of N560 to burn thru
LOL I switched from N560 to RE26, 2970fps 24" barrel. So similar speeds but find RE26 more stable of the two. N560 59.5gn and RE26 61gn. NB 280AI.
Yep 280AI, 24 in bbl. very similar load from memory right around 60gn N560
Not a .280 but a 7x64,
3/4 to 1" five shot groups with an older Sako AV.
I get 59gr R26 rem brass, 154gr SST, speed not checked,
60gr R26, rem brass 154gr SSt for 2890 fps,
61gr R26 rem brass 154gr SST for 2960 fps,
further testing in progress.
I have been sent quick load info, for the 162gr ELDX, in the 7x64, with an absolute max, of 59.6 gr R26, rem brass, 3.375 OAL, pressure 56000psi, 2914 fps estimate in a 22 in tube.
Make sure the QL info uses the H2O capacity of your fired brass. 7x64 is a ballistic twin for 280.
thanks guys
Data I have from quick load, for 7x64, interchangeable to .280 Rem, start low.
Cartridge : 7 x 64 Brenneke
Bullet : .284, 162, Hornady ELD-X 2840
Useable Case Capaci: 58.362 grain H2O = 3.789 cm³

^ thanks southernman
I'll run that with RE26 in QL.
staggering difference between RL 25 & 26 .... seems weird.
I thought Alliant stated when they introduced RL 26 & 23, that these were just more temp stable versions of 25 and 22 ?? really ?
As close as I could get with RE26 to 60kpsi with @southernman data.

thanks mate ! ^^
so finally chronod some loads .
so finally got to range to chrono me loads.
280rem Browning A Bolt- 162eldx over RL26.
3 shots averaged.
56.5g-2750fps 75fps between highest and lowest. 1 x lightly sticky extract- no extractor marks
57g -2795 fps 122fps between highest and lowest.1 x lightly sticky extract- no extractor marks
57.5g -2780 fps 23fps between highest to lowest- no extractor marks
58g - 2819 fps 36 fps between highest to lowest.1 x lightly sticky extract- light extractor stamp
58.5g - 2844 fps 69fps between highest to lowest- extractor stamp
59g - 2921fps 7fps between highest to lowest- decent extractor stamp
I am unsure if my old chrony is telling me porkies- so need to check with another newer chrony- and buy some new brass- as this stuff is 3 to 5 firings along.
2840 seems alright for 162s in 280 rem?
It sure is a please to shoot suppressed.Attachment 114409Attachment 114410Attachment 114411Attachment 114412Attachment 114413Attachment 114414

Those are some massive velocity spreads, heres hoping the chrony is misbehaving a bit or new brass helps. I'd have thought you would get a bit quicker before getting pressure signs like you are, seems like either funny reading or something else might be amiss
exactly what i thought mate- i was very methodical and finicky with powder measuring too, weigh- remove re weigh- remove re weigh ...Quote:

yah- i have to get new brass to start fresh- and borrow mates chrony to be sure. I was at the range tryn to remember the speeds you had posted for 162s in AI- .Quote:

Just the bottom one on my phone looks too hot. Play with seating depth. Then may be try a primer swap from LR to LRM or vice versa?
Ejector stamp is visible but what you don't see is your primer pockets enlarging as well, these usually go hand in hand.Quote:

thanks mate- yeah sorta wanna kill 2 birds with 1 powder
if i can :)
edit- oh i see n560 will do 7mmrm also....
You don't need a 7mmRM if you have a 280AI ;)
N560 works well in both.
I know I know- the 7mmrm is not mine- im happy with 280- killed 4 deer out to 450 :), just not happy with lack of rl26 :)Quote:

Groups and validation next.
R26 now September according to the importer.
That's good going! I get 2835fps with a max load of Hybrid 100v but in a 24" barrel. Might have to try some RL26!Quote:

No velocity increase past 60g of RL26.Happy with these figures for 60g.
Lightly flat primers- hardly noticeable- no other pressure signs at all.

Nice work @ANTSMAN
Thanks for the update @ANTSMAN
I was told yesterday they continue to tinker with 26 and it’s putting some off as there are discrepancies between batches?
Nice velocities there, I’ve begun loading up using the last of my R19.
Anyone tried 17 or 2213 or 2217 as I have a heap of R17 still.
