Tried it in my 30X8MM Mag,didn't perform well at all with the 200gr Noslers.
Just isn't as consistent as 7828.
My 30X8MM Mag is very close to the 300 WM.
Buddy at work is using it in his 300RUM,says
he is having problems getting loads developed that are consistent,cannot get the same speeds that other powders are giving without the pressure signs.
He says it appears to be temp sensative.
I had high hopes,but to no avail.

I'm using in a Lazzeroni Warbird, and it is shooting very well, but I haven't used a lot of other powders in it to compare to.

I got my 338 Ultra before there was a lot of data available and tried RE-25, H-1000, IMR-7828 and to a lessor degree RE-22 and H-4831, all under a 250 grain bullet.
The Reloader 25 gave the best results as far as velocity and accuracy. H-1000 was second.
I hear that other people have had simular results with the 300 Ultra also.
It doesn't seem any more temperature sensitive than any other powder and is really consistant for me.
If the weather ever straightens out, I plan on trying it in my 8mm Mag with 220 weight bullets also.

It really makes my 7 STW shine. Now I'm trying it in the 338 Lapua. Haven't got it to the range with the new loads, but I'll post when I do. - Dan

Z I'm not sure what your Buddy is doing but I doubt RL25 is the cause of his problem.I've used it in the 7mmSTW and found it gave me the highest vel and the best accuracy . In the 300 Wby accuracy was good but velocity was about 75 fps less than I can obtain with 7828. In the 300 Rum it again gives top velocity and accuracy.I have also found all of the Rl series of powders to be very consistent and easy to light.I get better accuracy using std large rifle primers in the 7mmSTW even in cold weather.And trust me we have our share of COLD in Manitoba.

I have been following this thread with a good bit of interest because RL25 appears to be the ideal powder to use in my 22-250 AI which is set up to shoot 80 grain bullets. My question is "Should I be using magnum primers with RL25 even though my load is only 44 grains?"
My present target load consists of 38 grains of RL22 with Federal match rifle primers and 80 grain Bergers for 3110 FPS out of a 24" barrel. This load is about 5 grains less than if I fill to the base of the neck with powder, which is the reason for trying out RL25.
Initially I loaded up a few cases with RL25 starting at 38 grains and working up in 1/2 grain incriments to check for pressure signs by measuring the brass base as well as looking for signs of primer flattening. No measurable case expansion at 44 grains, which filled the case to the base of the neck. Then I loaded up 20 rounds at 44 grains to check out accuracy. At 300 yards I got quite a lot of vertical stringing, so I checked out the velocity with a chronograph. 10 shot velocity spread was in excess of 50 fps. I don't remember the exact number without looking thru the book but it seems like the spread was something like 80 or 90 fps.
My gunsmith suggested that the 24" barrel is just too short to work with RL25, and perhaps he is right. My thought is that maybe I need to go with a hotter magnum primer to get a faster burning cycle.

Reloaders web site showed pressures of around 60,000 psi for RL25 for 300 wthby. I used it with 200 gr sierras and was getting velocities as high as 3240 and SD of 60. I do not remember the charge I was using. The pressure kinda worries me. I'll stick with 7828.

i also shoot 300stw and 8mm rem mags. have a couple of each. i relly like rel25 in both guns. all have 26" lothar barrels. 180 scirroccos at 3290 fps sd of 28 fps. the 8 shoots 220 hornady at 3085fps with sd of 16 fps. i have an older batch of aa8700 have 1 pound left from 8lb keg and it shoots the scirrocco at 3370fps with a sd of 6. will shoot under 1/2" 5 shots any time i have shot in 7 years. i have new 8lb keg of 8700 and it is not same grain size and i cant get the velocity with it. accurate arms has no reason for this. 300 stw

Dan,Snowman, I load 82gr of re25 in my 7stw and get 3400+ with a 150nos.bt. I was wondering what your load is. thanks fws

Hi Toto and Snowman. I'd be curious about the other loads as well. I'm using 80 gr of RL25 behing a 175 gr Sierra. Right now I get 3050 fps and no pressure signs. With 160's i get 3200 fps with Barnes x, 83 grs. With the Nosler and fail Safe 160's I can only go to 81 grs, which gets me 3276 fps with the Noslers and 3306 fps with the Fail Safes. This is out of a 24" barrel at about 40-45 degrees F. I haven't tried it with bullets any lighter then that yet. Well Snowman, now that REAL winter has arrived (could be worse, you could be in Thompson or Churchill)how about posting some of your loads? You must have more computer time now. Take care. - Dan

Snowman,
I was talking to Joe at work about his using RL 25 today.
He told me that with his 7MM STW he was having better luck than with his 300RUM.
I do not know what bullets or wts he is using in the 7 STW,probably Nosler if i was to guess.
The 7 STW has a 29" tube vs the 26" on the RUM may have something to do with it according to him.
I don't know what the problem may be with his
rifle,but in my 28" tubed 30X8MM Mag i was not impressed with the accuracy.
I do not have to have the fastest load,just the most accurate.
I have used RL 15 and 19 with success in some
other rifles so i had hopes for RL 25 as well.
I will continue to try it with different bullets and wts,maybe something will come together.

I am getting almost 3400 fps out of 180 gr noslers in my 300 ultra mag using re-25.Accuracy is averaging 1/2".

toto & dan My 7 STW has a 28 in barrel.A max load in this rifle with the 139 gr Hornady SST is 84 grs of RL 25.Best accuracy is with 83 grs. Vel is a little over 3600 with 84 and just under 3600 with 83.About 80 grs with the 162 gr Hornady is close to 3400 with good accuracy.In the 300 Wby I had tried Rl 25 with 180 bullets and found max vel was about 3125. A max load of 7828 in the same rifle gives me 3200 with better groups. I didn't pursue that very far.This spring i would like to try a Ruger # 1 300 Wby and seat the bullets out close to the rifling. In my 300 Rum with 25 1/2 in barrel a max load of 95 grs of RL 25 gives a 180 gr Barnes X an honest 3300fps. That load groups under 1 in @ 200 yds.Factory 180 Noslers and handloads with 7828 were grouping in 3 inchs an 200 yds so when I worked up to the RL 25 & Barnes combination I stopped right there.I would prefer to save the rest of that barrel for hunting.

<Varmint Hunter>

Here is what I recently got in my 7STW w/26" Hart bbl.
82.5gr RL25 under 139 Hornady SST loaded .005" into the leade and a Fed 215 primer.
Velocity aver: 3,294 SD 25
Group @ 200yds .35"
I only had loaded enough for one group with this powder so I will have to wait till next week to determine if this accuracy can be repeated.

OK, back to the ORIGINAL question......

Yes, Rel 25 works great in my 300 Wby.

Barnes X Max of 87 gr gives 3176

Nosler Partition Max 90 gr gives 3245

Sierra 180 SPBT Max of 88.5 gives 3172

Nosler 200 gr Partition max of 83.2 gives 2940

Hornady 220 RN max of 81.6 gives 2809

All load with Fed 215 primers

Start lower and work up.
