I sent a non shooting 325 wsm in a model 70 to jes in oregon to be rebored to a 338-300 wsm. He said reboring would clean the barrel up this was one of the last ones to leave new haven whoever was in charge of the barrel making that day did not give a [bleep]. Why not rebarrel it to a 325 wsm again well i bought another model 70 in a 325 wsm (south carolina) Anyhow i know folks were having 338-300 wsm made thinking winchester would introduce it. Anyhow if anyone has load data for 210-225 bullets be pretty cool. I have RL 17, imr 4007, aa4350, imr 4350, h414, h4831 and imr 4831. Thanks!

Would be interested to hear your results over time with this. Sounds like a cool project.

Its looking like i will have to do the load work... Once i do i will post results as of now from what i read getting 2800 fps with a 225 will be hard to do. But most article or posts were written before rl17 and 4007 were on the scene. Most foljs were using rl15, h4831 in the 338 wsm.

very cool project......rebarreling my 325 to a 338 WSM is an interesting proposition....wonder what it'd cost

I'd personally split the difference between the .338-06,.338 RCM and the .338 Win. Mag, and also compare to the .325 WSM, that should be right in the ballpark. I looked through all my sources and couldn't find anything.

I'd start with 325 WSM, 220gr bullet data and carefully work up from there.

338/.300 WSM is listed in QuickLoad...

I don't have Quickload, maybe someone could hook the man up?

alrighty. take this knowing it is a prediction and I assume you know the rules (work up and watch for pressure)

out of your powders, RE 17 should give best speed, and a 225 gr. NAB loaded to 2.85" COAL over 66 gr. RE17 (MAX) will deliver 2870 fps from 24" barrel at max SAAMI pressure(63817 psi). this load is RIGHT AT MAX!

i'd start at 64 gr. for 2790 fps @ 57409 psi

Thanks! That was the plan to ladder load start at minimum and work up 1/2gr incraments.

I built one of these ages ago after wearing out a couple of barrels as 338 Jamison. I did it when the first 300WSM came out and merely necked those up. Much easier for cases than the Jamison. All are basically the same with the Jamison having a bit larger powder chamber. Football game starts now so give me some time and I'll post as much info as I have on loads. Don't recall any right off hand. Makes a nice rifle!

This should get you in the ballpark:

Code
Cartridge          : .338/300 Win Short Mag [WSM]
Bullet             : .338, 225, Nosler AccuBond 54357
Useable Case Capaci: 66.402 grain H2O = 4.311 cm�
Cartridge O.A.L. L6: 2.860 inch = 72.64 mm
Barrel Length      : 24.0 inch = 609.6 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 63500 psi, or 437 MPa
or a maximum loading ratio or filling of 110 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
USE ONLY FOR COMPARISON !

55 loads produced a Loading Ratio below user-defined minimum of 70%. These powders have been skipped.

hmmm. what version of QL do you use? mine is V3.6... my default case capacity (h20) for this cartridge is 66.419 gr. that's all I see different but our outputs differ quite a bit. my 'weighting factor' is .5 and the shot start pressure is 3636 psi. are those both the same default values as yours?

and how did you copy those charts here?

Same version, same weighing factor. I haven't' modified the start pressure so I assume they are the same.

I set the powder lot variation at the lowest level, 3%, and in this instance used a 24" bbl (since that's what most short mags come with) I also up the usable capacity to 110%, and set .5 gr increments instead of the crazy % default if uses.

as for copying the charts,
begin with the word code inside of []
end with [/] and the word code inserted after the slash.

Also QL gave a max pressure of just over 64k, so I back if off to 63.5K so the big list didn't show "dangerous do not use"

These are just a few things I've found to make the data more useful.

ok. looks to be the powder lot variation producing the differences. good idea there. I also used 24" barrel length.

thanks for the code lesson. i'd have had to take a screen shot and host/link that as a .jpg

210 Noslers, H414, 65g, WLR primer, 2750fps, .76" group. Water volume of the case to the mouth was 80.5g, worst batch of Norma brass I ever saw. Same brass on all loads.

215 Sierra Game King, H414, 68g, WLR primer, 2780fps, .831" group.

BEST LOADS
215 Sierra Game King, H4350 66g, 215M primer, 2785fps, .490".
" " 69g, " 2795fps .621"

210 Nosler, IMR4831, 71g Max, 2805fps, 215M primer, best group 2.1".

225 Hornady, IMR4831, 72g, 2778fps, WLRM primer, best group .495".

225 Hornady, H4831, 74g, 2744fps, WLR primer, best group 1.034".

I was using Pressure Trace equipment on these. Most of these loads were right at 65,000 lbs. Barrel was 22". Be careful! I had pierced a few primers and had extractor marks before I used the Pressure Trace. This was about the time I quit being a velocity freak. You don't see pressure signs till you're usually well over safety.

I have quite a bit more data on other powders, particularly the VihtaVouri line. Good luck with N560, not so good with N100 series.

Good luck.


Found another with H414, 210 Noslers. 65g, 2750fps, .76" gp.

Update been hard at with this thing I was getting well over 2800 fps with rl 17 but accuracy not their I was using 225gr hornady. Then switched to 210gr ttsx using rl19 accuracy was promising but stopped with this load went back to 225gr bullets. So switched to rl22 accuracy is their with 225gr accubonds and 225gr hornady sst, but my chrono broke I need to go buy another one I have no idea what the velocity is as of now.

I use 200gr Accubonds with 66.5 rl17. I’m going to give rl26 a try in it with 225gr bullets. I couple hundred 225gr Accubonds.

66 gr with RL-17 for your 338-300 WSM with the 225 accubond sounds about right.


My 22" 338 RCM using 225 accubonds: uses 61 gr of RL-17 for 2750 fps


Now if you want some serious thump you could try the 300 gr Berger OTM. My load: 300 gr Berger 54 grains of RL-17 vel 2350 fps. Fits and feeds from 3.050" magazine.
I would imagine you could get 2400 fps or more.


A poster on LRH, Broz, reported velocities with his kills with the 300 gr OTM bullet. I calculated that even with this sluggish bullet it would be quite lethal out to 550 yds or a bit more Your rifle would extend the performance even more.

Broz:


"We took two elk today with the Berger 300gr Hybrid OTM from my .338 Lapua mag. Bullet performance was pretty much identical with 1 1/4 to 1 1/2" exits."


First was at 825 Yards and a rib cage shot. Impact velocity was 1966 fps. Exit was about 1 1/4"

"Bedded cow at 816 yards. Impact velocity was 1975 fps. Cow was slightly facing away. Entrance was in the crease behind the near shoulder. Exit was far shoulder. I was kinda surprised that the exit was only 1 1/2" or so. But this exit is deceiving. Note the bone fragments on he hair around the hole. Inside was total destruction and the exit shoulder was a loss. Elk died quick and clean. I am pleased."
