Anybody loading for the .35 WSM (AKA .35 Sambar or .35-.300 WSM)?

I know someone else here has built one already, but try working carefully up from .358 Norma loads (not that there's a lot of that data either)

Thanks. I've already been looking at .358 Norma loads. The .35 WSM has about 95% of the case capacity of the Norma, so I plan to reduce Norma start and max loads by 5%. However, I've not yet seen any .358 Norma loads using RL17, which is what I want to try next. Since RL17 and IMR4350 are alleged to have very similar burn rates, I've loaded up a series using RL17 and the 250 Speer Hotcor, starting at 63 grains and going up in 1 grain increments to 68 grains.

Any opinions anyone, before I go to the range next week?

My Bansner built rifle works very well with 75 grains of RL17 and a 225-grain Trophy Bonded bullet. I use a Federal 215M primer and Winchester brass. I get 2,950 fps and excellent accuracy. I have used it on elk, antelope and whitetails all with great performance. Of course, start lower and work up as this is a max load in my rifle.

Thanks for the info Bryce.

And Lawdwaz, I appreciate your asking your friend.

Also, I received QuickLoad projections from Toad via PM. Thanks again Toad!

Anyone else have any suggestions?

If I succeed, here's a pic of my MRC barreled action fitted into a Winchester Featherweight stock (lotta work there):

in the full screen reply there is a toolbar right above the box you type into. it has an "enter an image" box to click on and then paste the url of your pic.

or hover the mouse over your pic in photobucket and there should be "[img/]" tags already attached to your picture that you can just copy and paste that into your reply directly.

but i have a SS M70 Classic WSM that i would love to do the .350 WSM with, but alas i've had an "unexpected intruption in disposable income" so i'll have to do without for now...

Here's what I got....my friend started out with some VV N550, didn't get great accuracy and found it to be temperature sensitive. He has had some better results with Varget, starting with 66 grains and ending with a MAX load of 68 or 68.5 grains. Bullet used for these loads was the 225gr Accubond. I'm sure I don't need to say it but....use caution!

My 35-300 WSM is a Ruger 77 Mk II. Its favorite light bullet load is 73.4 gr of Reloader 17, Barnes 200 gr TSX, Federal 215 mag primer, and Winchester brass. MV is about 2950fps and accuracy is very good. I started at 66.9 gr of powder and worked up.

I am running 74.0 gr rl-17 with a 225 Nosler Bt using necked up 325 brass. 2835 fps. This done on a Savage long action. So I can seat the bullets out. Shoots 1/2 moa

Interesting wildcat. That originated in Australia didn't it? Named after the Sambar deer? Sounds like it can do some heavy lifting but with acceptable recoil.

I've been up to 72 grains of RL 17 in the .358 Norma with 250 grain Speers for 2875 fps.

what is the difference between necking a .325 wsm up to 35 caliber and a .300 wsm necked up to 35 caliber.

PM SENT.

Jerry,
That powder has a "burn rate" that is too slow, for the 358-WSM.

Today, I was working with some 250 Hornady RN's (Not Regestered Nurses).
Having worked with a lot of loads and several 225's (Swift A-Frames. TSX, and Partitions), so, I had a clue as to where to start with my 250s.

I started load development in 2005 for my 358-WSM, and burned a lot of the slower powders such as 4350, 4831, and RL 15..., They are all too slow for optimum performance out of that cartridge.

I sent you some load data for the 225's that show them easily doing over 2900fps.

Check your mail box.

Shot some 225 TSXs over 65 grains of H-4895 today as well as some of those 250 grain Hornadys...

The load for the 225 TSX was one I did up in 2005 for a Moose load at possible long range.(ended up going with 64 gr. under the A-Frames)

Admittedly, it is a bit warm, and 64 grains is much perfered.
(well within an inch for 5 shots - Thank You Pac-Nor))

Anyway, I put 2 of those TSX loads over the chronograph that were slightly above 2980 fps.
Backing off a grain, things were looking much better as far as primers and bolt lift go...but was still firmly in the mid 2900's.

Working with the 250's...

Since I has such good results using a 250 Partition out of my Whelen at just under 2400 fps this last fall, I was inclined to see how they were in the 358-WSM.

I ran 5 over the chronograph today with 61 grains of H-4895.
-2659
-2658
-2661
-2677
-2651
-------
2661 avg. (all 5 clustered within an inch)

My avg from the previous load using 60 grains of powder was 49 fps behind.

I imagine that there is a sweet spot somewhere around 62 grains, which will put me in the 2700's.

358, what barrel length are you running? those are some pretty good numbers!

TOAD

My barrel is 24"
(...and I have given serious thought chopping 3" off)

It is a Pac-Nor. I was recently told here on the fire in an unrelated discussion, that the lapped and polished barrels will often give us a free 100 fps. I believe this could be part of the reason I am getting such good velocities. When I first started loading I noticed that I was a bit ahead of other 358-WSM numbers, but always attributed it to the H-4895 under those 225's.

I will say that with 250's 2800 fps is probably the realistic velocity ceiling.

ALSO, allow me to back up a step and say that every bullet and every bullet weight responds differently with different powders.
I previously stated that powders in that burn rate area which are near 4350, 4895, RL 15, and the like are too slow on the chart to give best velocities in the 358-WSM, "with 225's." I have tried them.
Again for them, H-4895 is "THE" powder.


As for the 250 grain bullets, they 'might' respond differently to RL 17. (Notice the numbers Bryce posted)

He shows 75 grains of RL 17 pushing 250 at a respectable clip. Now, I dropped 75 grains onto the scale last night and if I charge the case through a 12" drop tube it still requires me to compress the load with 250's and a 2.925" C.O.L.

Although I have not had a chance yet (maybe tomorrow I can report), I am expecting 62-63 grains of H-4895 to give me excellent accuracy and acceptable pressures. With 63 grains, I expect to be knocking on the door of 2800fps.

Personally, I would accept any 250 grain numbers in the 2700's fps. as long as I had the accuracy.

Remember - A bullet of a B.C. above .400, when zeroed at 200 yards will only show one inch differance in tradjectory at point of impact when it reaches 300 yards, when velocity is 200 fps slower/faster.

In other words, 100 fps will only allow me 1/2" flatter tradjectory at 300 yards with a 250 gr. Partition.

100 fps. give or take doesn't excite me much with bullets of this weight and caliber.

what is an eye opener, is you guys are getting the near the speeds from 250s that i can wring from 200s in my .350 RM. i also agree that 2800 from 250s would seem to be the upper limit (QL sez 71.5 gr RE15 should give 2801 fps from 23" barrel). that's a significant step up.

i gotta get one made...
