Anyone here with experience with Alliant Reloder 25? And, in particular, with the .270 Win. or .280 Rem. It would appear to have a burn rate similar to Re26. Since it is a lower number than 26, one might expect it to be slightly faster burning than Re26, but the opposite appears to be the case from my explorations of it via QuickLoad. It takes slightly more of Re25 than Re26 to get the same velocity. For the cartridges I'd like to use it with (.270 Win., 6.5x55), the lower bulk density of 25 compared to 26 makes it something of a challenge to get enough of it into the case for top velocities.

I used to use RL-25 in my .300RUM with 200gr bullets. The burn rate is between H1000 and Retumbo. Personally, if I were you, I would forget about RL-25 and with the cartridges you are looking at RL-23 would be the ticket. RL-25 is the dirties powder I have ever seen. It is much like RL-19 and RL-22 for being temp sensitive. RL-23 is one of the most temp stable powders on the market>>period.. I doubt you could find a better powder than RL-23 for the applications you are listing..
Not in the cartridges you mention (270,280) but in 25-06. I load RL 22 in my 280 and have never looked back. I tried RL 22 in my 25-06 and pressure got high before I reached my velocity target, so I tried RL 25 and got my target velocity or within 25fps of it. No pressure indications and shoots very well in my A Bolt II. I once took that rifle after I worked up that load and over a 6 week period I would fire one shot cold bore every 2 weeks, ended up with a 3 shot group that measured .678". Which fits my requirements for deer hunting. Good luck.
I tried RL25 in my 7mm Rem Mag & 280 Rem.
Along with RL23 & RL26.
Now using RL26 for the Rem Mag. About the same velocity as RL25, but much better accuracy.
For the 280 Rem, i've gone to Alliant PP4000MR. Good accuracy with up through 150gr bullets, and good speed. Not as bulky as RL23. By a long shot!

Yes, I wondered about PP4000MR. Unfortunately, it's not included with QuickLoad, so hard to tell how well it would work with the .270 Win. and 6.5x55.
Yeah, the Power Pro series hasn't been released for Quickload to do their thing.
Too bad, as it didn't take them long to release RL23 & RL26.
And any new Hodgdon powder shows up on the next update.
You might PM @Alliant Reloading.
Or give them a call.

Brother and I have been shooting R#25 in the 26" barrel 7 mags for years with 150-154g bullets. We load at the range. When we went from a Federal 215 primer to a Winchester MAG primer, all things came together, SD, ES, Velocity, and Accuracy. SD is 9 on our load at 3250 fps with the 154g Hornady Sp. with accuracy of sub 3/8" groups! You could triple all the numbers with Fed 215's! The Win Magnum primer is a very different primer than the Federal 215 in terms of fire and incandescent particles produced by the primer.
Some years ago, I found a load for my Remington 280 right out of the nosler manual #4. 160g at 2900 out of a 24" barrel That is extremely accurate with great velocity. I found the results with the load amazing to say the least. IN later manuals, Nosler had to dumb down the 280 loads due to pumps and semi auto's.
In a 280 Rem Factory bolt gun, the IMR 7828, Fed 210, 160-168g with the 280 is a tough combo to beat!
IMR 7828 is the powder, and the Federal 210 primer sealed the deal on very small groups.
IMR 7828 with the 280 AI with 160-180g bullets worked extremely well, and I can not stress enough the use of a fed 210 primer if you are trying to achieve groups were the bullets open up a bullet hole.
A good friend uses IMR 7828 in his 270 winchester with amazing groups with speed.

Anyone have experience or comments about RL-25 in a Weatherby 257 Mag.? This one has a new barrel with zero freebore. RL-25 shows well in some of the manuals that I have, for some weight bullets, doesn't show at all for others. It was unavailable for a while, but I grabbed a bunch when it became available. Wby and Hornady brass, thus far Sierra GameKing 100 grain, CCI-250 LRM primers. I have just acquired a supply of CCI-34 primers, enough to stick with for load workups and general use. I have shot H4831 a little as part of the break-in and have an equal supply (to the RL-25) of IMR4350 that could be used. Haven't gotten serious with working up loads yet, but plan to very soon.

It'll work better with heavier bullets.
Probably something in the 115gr- 120gr.
That Weatherby case has a good bit of volume.
You might try RL23 with the 100gr bullets.
RL23 is fairly bulky, so will fill the case better, and the burn rate would be better suited with the 100gr bullets than RL25.
110 gr. AccuBond, 115 gr. Ballistic Tip and Partition and 117 gr. Hndy SST are the heavier bullets I have so far.
Those will all work!
I haven't shot any yet, but i hear not to underestimate the performance of those 117gr SSTs.
They supposedly are much stouter (hold together)than the 7mm or 30 caliber bullets.
The 115gr Ballistic Tips are my most used 25 caliber hunting bullet. For me, they perform much better than the 100gr BTs.

I tried R#25 in my 257 Weatherby with zero freebore with 100g bullets, velocity suffered over R#22. My guess was that the 25 in this caliber needed the heavier bullets, and I did not go there. My R#22 load is 3850 fps, shooting .300 three shot groups and smaller, zero freebore chamber, 26" 10T barrel.
R#25 LOVES Winchester mag primers in my 7 Mag over the Federal 215's.

The 280 load with IMR 7828 with the fed 210, 160g is real world, not fiction in several 700's! You will suck hind tit if you go off of book factory loads for the 280, they ham string the cartridge for reloading right out of the gate with low pressure loads for pumps and semi auto's.
With the 7 Mag with R#25, 150g-154g bullets, Win Mag primers shoot groups so small you will not believe it, 700's, Browning A Bolt, and one Savage! The accuracy node is a HOT load. I had my cousin shooting 1 3/4" clay pigeons at 300 yards with his Savage/wood stock bedded with bbl freefloated with a junker cheap Bushnell 6x18 scope.
All other primers SUCK with the R#25 in the 7 Mag. Brother shoots 168g Berger vld hunting with R#25, around 69g. It was a come to Jesus moment when brother changed from 215's to the Win mag primer.
In the 7 mag, the R#22 with a CCI 250 has a single bullet hole node at 2850 and with R#26, 3030 fps, 175g Nosler long range accubond.

I would think that in a proper twist, 257 Weatherby with 131g Black Jacks, that R#25 with a Win mag primer would be a great combo, but there are several powders that should be exceptional.
R#23 and 26 are not to be found, Win Mag primers have not seen in years on the shelf.
Reloaders are on one heck of a mess at the moment with the lack of availability of components.
