Hello,

Wondering if anyone has used any of Alliant's new RL26 in their 7RM? If so, what kind of accuracy and velocities are you seeing with 160-168grn bullets?

Plan to give it a try in my Sendero (26" factory tubes w 1-9.25" twist) and wanted to try something besides H1000, 7828 or RL25.

Any help appreciated, have some berger 168's and amax 162's on hand.

Thank you,

SD

Fotis,

Thank you sir!

SD

You bet!

Fotis can you post similar data with RE23? I am shooting a Shillen 26" barrel on my model 70 7mm rem mag. In particular, 160 AB, 168 ABLR and Berger VLD, and 175 ABLR.

Thank you so much.

No 23 data on Q/L and I do have the latest version. BTW I heard that 23 and 26 will replace 22 and 25.

23 & 23 may replace 22 & 25 in the RL product line, but Alliant was quick to inform me that the data was interchangeable when I contacted them with question regarding 23. Just an FYI.

Odd that Q/L has data for 26, but not 23. Any idea how long ago the 26 data was added?

I was thinking that 23 would be a hair slower than 22.

In my 7 wsm, this is not the case. With 120's and 160's max charge wt with 22 = max charge wt with 23.

120's were 50 fps faster with 23, but that could be a quirk.

Testing some 26 next with the 7 wsm and 300 dakota.

Alliant,(Duane), confirmed the burn rate of 26, "it is slower than 25 but faster than 33". I inquired about 23 too, but have not yet received a reply.

SD

I bought the update a week ago.

According to Q/L 70 gr of RL 26 with 160 gr AB in a 7 mag produces a minute amount of more pressure than RL 25 loaded in the same way.

Reply about 23 from Duane at Alliant.

"Reloder-23 is slower than Reloder-22. The load data for the two of them is different, it is NOT the same. All of the Reloder series of powders has anti-copper additives with the exception of Reloder-17. Reloder-23 will be pretty much used in the same places as Reloder-22.

Thanks

Duane"

I disagree. I'm almost done with my second pound of 23 thru a 7 WSM and it's basically the same as 22 (maybe a hair faster).

Fotis-

Would you run a 7 wsm with 23 ? 120 ttsx and 160 NAB?

2.860 oal and 24" barrel.

Thanks-

Judd

Fotis you are a kind person. Thank you for the help and the data.

FH

Fotis that's an interesting table to read through.

If that's what a 7mm Rem Mag looks like at 65,000 psi I suspect I've never loaded that hot. Anytime I saw over 3100 fps with a 160 gr from the cartridge I'd stop and throttle back a bit.

But it does show how much better some of these modern slow burners can be in the cartridge.Can't help but wonder how they'd hold up in real life. That first load with V N570 grabs my eye.....77 gr for 3253 fps at 65,000 psi, That's a lot of velocity from the cartridge with a 160. Ditto for the RL33 load for 3238....Good to remember this is for a 26" barrel.

Interesting.

Anyone know how does QL arrive at its figures anyway?

When I did have one I saw 3100 fps with H1000 but that was long ago.

Please be advised. This is only a simulation, although I have found it to be very accurate in most applications! YMMV

I have worked up with 3 powders in this group and just did a comparison for velocities generated on my Oehler 35P in a Model 70 with 26" barrel. Using Federal 215 primers, my results were:

Quickload
72.3gn H 1000 = 3149fps
67.9gn Rel 22 = 3148fps
73.7gn Retumbo = 3111fps

My loads Chronographed
73gn H 1000 = 3011fps
67gn Rel 22 = 3134fps
73gn Retumbo = 3057fps.

Interestingly, my Rel 22 load averaged .602" during testing. The Aussie powders were 1.5 - 2.5" by comparison.
John

AGW: Interesting.

I've found RL22 to give good accuracy as well.

Fotis-

Thank you very much. Your predicted speeds are very close to what I measured.

I've got to get that software.

Thanks again-

Judd

it is priceless!

I'm pretty sure if you put the quickload data between [code][/code] it'll show up on the 'fire as much more reader friendly.

much better in code

Hello guys!

I'm new in this forum but I've been reading your posts for some time and I was wondering if any of you could run the QL so I can have an idea of how this powder (Reloder 26) works on a 7mm rem mag with 24" barrel, using hornady sst 154 gn and hornady sst 139 gn with federal 215M primers...
Thanks

Another +1 for RL-26. Tried it last weekend for the first time in my 7mm WSM with 162 A-Max bullets. Really good accuracy! Loading up a bunch more and will bring the chrono next time.

Try some Re33, also. Works great with 160s and long barrels.

Bob,

I got some Vv N-570 to try in my 26 Nos, hearing it was a good one for that round. I saw a QL print out that showed it as top performer in the .300 Win Mag with 200 gr. bullets.

It's a real coarse stick, just about won't work in a powder measure. I had to remove the RCBS Uniflow drop tube, stacking was so bad. I drop a charge without drop tube in my scale pan, adjust to weight, then funnel into the case.

It's a high energy powder and doesn't over fill the case, at least the Nos. Haven't dropped a load in either .300 Win Mag or 7RM.

RL-33 is a favorite among some LR .264 WM shooters with 140's.

DF

I just scooped 65lbs of '26. I'm banking on it working good lol

You better hope it works...

DF

http://www.alliantpowder.com/reloaders/powderlist.aspx?type=1&powderid=40&cartridge=73

If I can find some of the stuff I wanna try it in the 7mm Mashburn with 175's. My rifle does well with H1000 and 175 PT's at 3050, but it seems like RL33 might free up a little speed. It is hard to mess too much with the current load as it shoots really well, but I can't resist giving it a whirl..



Retumbo looked pretty good as well, but around me, RL33 seems to be easier to locate.

Scotty: Not shabby....





Dirtfarmer: Those VVN powders are the beotch to locate around here....

I tend to stick with the local available stuff and am ready to try some of the new Enduron 7977 in the 7 Rem Mag. Bought 2 pounds.

Powder Valley had 570.

http://www.powdervalleyinc.com/

DF

That V570 is some awesome looking powder in most of the QL profiles for the big jugged 7's. If I saw it locally, I'd bite the bullet and HAVE to grab a pound..

I got three pounds, just to try it out.

Big cases consume a bunch, a pound doesn't go that far...

DF

There are 6,000 grs. in a pound.

At 90 grs. a pop, only 66 rounds out of a can...

Long way from my Hornet...

DF

7000, but yeah...

Close...

DF
