When pondering a new rifle last year and wanting a magnum my research landed me on the .325 WSM. I have to say it has more than impressed me with medium recoil and power enough to hunt Dinosaurs. I have settled on Nosler 200gr accubond as a good bullet but am tossed between RL-19 and H-4350 powder,any suggestions?

Welcome to the "Nest" TX Steve.

If you want to milk the most FPS out of the rifle then go with RL-19.

H4350 is more consistant across all temperatures.

Have fun,

Bobo

txstevel,

Welcome to the 'Nest.

Both would be good powders. H-4350 will have a smaller load, slightly less MV, but a tighter window between the Max Pressure and the "V1" progressivity index (it's a good thing...). RL-19 will use more gr of powder, give you about 65 more fps of MV, but have a slightly wider "Pmax-V1" window.

The 6th ed. Nosler manual has a load range for H4350 of 60.5 gr starting, 64.5 gr Max. For RL19, the load range shown is 65.0 gr starting, 69.0 gr Max. They show H4350 being the most accurate powder they tested, too.

I'd say start with H4350 and see how your rifle likes it...

Thanks guys,the H-4350 has been my favorite in my 8X57mm with the Nosler BTBT 180gr bullet. I only recently tried it in my .325 after trying other suggested WSM powders like RL-17 which was accurate but nearly relocated my shoulder. Not in it for the hurt as I get older you know. Another question,has anyone tried Speer 200 gr.bullets?

I've been playing with that caliber all summer!, same as you - 200 accu, imr4350, rl 17 & 19, and 4007ssc..... after 400 rounds trying every possible combo i could put together, the winner for accuracy was 4007, spit the 200 out at 2950 and the most accurate, 3 shots is a ragged hole at 100, and my best at 200 was 1.2" with a light breeze... velocity (another 50fps) went to rl17 - but not as accurate as 4007. settled just under max load in both 4007 and rl17.....I played with 4350 and rl19, but just not the same performance and/or accuracy in my gun.... tried 200 sierra hp's and couldnt group them...same with the 175sp sierra - used all above powders... good, but not like the nosler...too bad tho as the noslers are $$$...was gonna try ramshot hunter, heard its good - but now that i have found that 4007 load, 'im thinking i'm gonna play shoot for a while and not focus on making any new loads!!!

Also, i found the COL played a big factor - i tried the 20 thou to 50thou off the lands, and my shots were all over - then seated all so COL was 2.86" and viola! they all tightened up big time. fyi my gun is a "m70 all weather ss"

Thanks I will double check my COL. My rifle is a Savage 16 fhss,my first Savage and impressive so far. My best group so far was .75in at 100 yds.consistant groups in all weather conditions is my overall goal.

I have no info on the brass life for the 325 using Winchester brass yet, But I do have some 325 reloading info. Recently I worked on a HS Precision custom 325 and found it to be difficult to say the least when trying to produce an ultra accurate load for it. The rifle had all the bells and whisles and a 24" barrel. The end result was a 3/8" group measuring from center to ceter at 100-yards.
Here's the load recipe:
Trim: 2.090
Case: Winchester
Primer: CCI large rifle magnum
Powder: IMR-4831, 67-grains
Bullet: Barnes 180-grain TSX, *** I moly coated them in a tumbler using Lyman's super moly. When seating the bullets I used a roll crimp.
OAL: 2.844
Velocity: 2,856-FPS

RL17 the BEST balance of short magnum powder!! I have never had a short mag, but if I did it would be that one. I load for a 270 wsm but it ain't the same, other than case. Still, if you are looking at those two powders, go get a pound of RL17 and you can thank me later.

By the way, Speaking of the .325 WSM Is the fact that I have a box of 200 grain accubonds and a few other various 8mm bullets lying around with no use for them a good excuse to go find me a gun to go with them??? I just saw your post Chrism With my results with 17 I am surprised you had any accuracy issues. I have been gettin extremely low ES and SD numbers like 3-5 and 1.2-3.1 with it. But not in a wsm, havent played with a wsm yet, gonna play with that .270 WSM in a couple weeks getting it ready for hunting season, I will see how it does.

cfvickers I have tried RL-17 and have a word of caution. When I loaded the .325 WSM just under max by 10% and pulled the trigger it pushed my chair back on 2 leggs with my big but in it. Thinking perhaps I messed up I tried again with the same results. My load info was: 200 gr accubond,both 63 and 65gr RL-17, CCI 250 primer , Win brass. Accuracy was good and this might not reflect the results with a smaller cal. Would like to know how you do. Good luck

In case anyone out there still checks this site I settled on my keeper load for my Savage 16 in .325 .
200 gr Accubond over 62.5 gr of H-4350 with Fed. 215 primers. I know there are faster loads but this
one with 3 shot groups had 2 holes touching and all 3 in a one inch square at 100 yds. I also enjoy
being able to shoot 23-30 rnds without a tired or tender shoulder. My kind of magnum!
Thanks guys

Glad to see the load work came together for you.

I load H4350 in my fathers 8 x 57 Mauser with Hornady 170 RN, 195 Spire Points and Nosler 200 grain Partitions with good success.

Have have,

Bobo
