I'll have to check to see if I have some. It seems like load data--what little there is--is all over the map for the 25, usually the assumption seems to be what's good for the 6.5 is good for the 25. I'm not so sure about that. Enduron powders and especially Alliant's reloders have been missing from the market for a long time, unfortunately--I really have a critical lack of reloader 22, 23 and 26. I did buy an 8 lb'r of 4000 MR and am curious about how well it works.

Yes--I have plenty of ram magnum, as you can see by one of the random test loads above it seems to shoot very well with it. I'll come back to it at some point, I just want to try some other powders since I have other magnum "gas guzzler" cartridges that I also fuel with ram magnum.
Was anxious to get out today to do some testing--but we got ten inches of new snow last night so I think all I'm going to do is rezero my HD5 since I put a new Warne 20 MOA steel rail on my rifle.

I'm thinking the Alliant PP4000MR may be a touch fast burning for your likes.
Some burn rate charts putting it in the 4350/RL17 speed.
It does seem to do well in cartridges with capacity in the high 40gr to about 56gr. (Read 284 Win & 280 Rem)
Go larger capacity, or heavy bullet weights & the velocity really drops off.
Hybrid 100V is my go to for the 257 Roberts with 100-115gr bullet weights.
Used in my 7mm Rem Mag with 150-168gr bullets, accuracy was good, velocities nothing to write home about.
Does, just ok in my 257 Roberts AI.
On the subject of burn rate with 25 caliber.
My 250 Savage seems to like a faster burn speed powder than what i would expect.
I'm using Alliant Varmint with 75 and 90gr bullets to good effect, with good velocities.
RL17 with 100gr & 115gr bullets isn't showing the velocities i was hoping for. Nor was H414 (W760).
I may have to play with a faster burning powder on those.

I went out today and tried out the 4000MR--decidedly mediocre results, only one charge was slightly under MOA at 174 yds, though conditions are less than ideal and the rests tended to slide around on the hood of my truck. The good part was the muzzle exhaust did a good job of blowing off much of the stubborn ice clinging to my hood.

Absolutely true--you're not the first to remark that. When conditions get bad I tend to be selective on erecting my full set-up. Where I shoot is an active quarry so any leave-behind is not an option. Further complicating the situation is heavy equipment and piles of product change every day, so I rarely even have the option of setting up in the same place twice. So I adapt.

You think report sound inside a house is bad? Try shooting in a truck bed--especially one with a camper top.
It's a big one, so I can usually find a corner where nobody is working. I'll pack up and leave if his guys want to work wherever I am, happens all the time. It helps that the boss of the company is a friend. : )
Yeah that would be badhttps://www.uline.com/Product/Detail/H-9134/Folding-Tables-and-Chairs/Plastic-Seminar-Table-30-x-20?pricode=WC1245&gadtype=pla&id=H-9134&gclid=EAIaIQobChMIldrOsv-l9QIV1sfICh1Q_gPUEAYYByABEgJafvD_BwE&gclsrc=aw.ds with a cap on. Would something like this help you out?

I can't tell you how many different versions of portable shooting bench I've tried--long story short--if there is ANY movement in the table/bench/rest--that is going to translate into where the successive shots are going to go. Centerpoint support plastic table--no way that will be stable consistently without lots of modification. Leveling legs on anything other than a flat level terrain is a big issue also.
I'm itching to go out and test fire again--but our weather has gone truly haywire--after getting dumped on with snow we were hit with a rain storm--and now an arctic front is cascading in which will drop our temperatures down to around zero by this evening. Going to be a glacial mess and a long night vigil if the power goes down.

Hopefully you'll get over the virus without any deep complications--I think I've already had it--twice (hospital refused to test me due to test shortage).

I know people who have died from it too--in fact a friend of mine got sick about the same time I did in early 2020 when it still hadn't really spread in the US and testing wasn't really available except for emergency responders.--neither of us knew what we had at first but we compared notes and we both had similar symptoms--except I got better and he didn't, unfortunately.

Trying to decide if shooting today is such a good idea--6 degrees above zero and wind chill well below zero. Got these cartridges using ramshot magnum and another pistol cartridge using H110. But the forecast says it's going to blow stink after today.

Maybe--depends how motivated I am and if I can get the labradar set up and stay up.
Just did a recon--it's already too windy to hassle with putting the stuff up and getting good readings (aka I'm a wimp) but I think I may try the PCC at close range. Currently it's 4 above zero and windchill is almost 20 below.
