Making .351 Win brass, educate me.

[koger]

I have a buddy who has one, limited amount of ammo. It throws brass every where. I have heard of folks making it from .357 mag turning the rim down, and or from .223. If you have done this, educate me please. All replies appreciated.

Hey, koger. I'm in the same boat. My friend has a .351 Win and he is facing the same question. I'll be following this thread closely.

Found some old reloading data that may come in handy:
10.0-11.0/Unique/180 gr. Jacketed, 1501 - 1587 f/s
17.0-19.0/2400/180 gr. Jacketed, 1597 - 1793 f/s.
17.0-19.5/IMR-4227/180 gr. Jacketed, 1400 - 1751 f/s.

12.0-12.5/Unique/171 gr. Lyman 350319 w/GC, 1692 - 1751 f/s.
17.0-19.0*/2400/171 gr. Lyman 350319 w/GC, 1861 - 2020 f/s.
17.0-19.5*/IMR-4227171 gr. Lyman 350319 w/GC, 1658 - 1904 f/s.

All the load data from this edition of Lyman's manual is on the hot side. It might be a good idea to revise the max loads down by 0.5 - 1.0 gr. The manual says accuracy with all loads was fair at best. Best results were obtained with the cast projectile and IMR-4227. Gas checks were .348". Loads marked with asterisks are compressed.

NOT that anyone here asked for my advice, but I think I'd look for a load that gives reliable function, and stop right there. I hope these data help.

While I can not tell you how to make .351 brass, I have used large shallow open boxes positioned near the ejection port to catch brass. I doubt that anyone makes a brass catcher for the .351.
On paper the ballistics of the .351 compared favorably to the .35 remington. on paper is said to be: 180 gr (12 g), 1,870 ft/s (570 m/s)

.35 remington is said to be: 35 Remington factory load (200gr bullet at 2,080fps)
The above data is for factory loads and could be optimistic.

40 + years ago I made some but don't remember the exact details. My cartridge conversion book says use the 357 maximum case, turn the rim to .407, cut a new extractor groove, trim to 1.58", size and chamfer. The book recommends a 180 grain .351 diameter bullet and 15 grains of 2400 powder.

Hope this helps.

If you check the archives, someone mentioned that he used the catcher intended for the AR platform.

They make a brass catch that has a Velcro loop that you can just Velcro around any gun…I use it for AKs and 30 carbines….not the HKG3 it tears holes in it

This is how I turn down heads.
The driver just fits the primer pocket.
Pusher rod is center drilled and a slip fit into the neck.
Cutter made to fit.

I watch U tube videos by Logcabinlooms, and he had some videos about shooting and loading the .351. One showed a brass deflector that he fashioned from a piece of heavy leather, similar to the tin ones on the Remington .22s, that let them land closer too your feet. Video was several years ago, maybe you can still find it.

I was lucky enough to meet a guy on Facebook that sold me some 351 brass 46 cases he had laying around. Yesterday I went to a shop looking for primers. I ended up walking out with 11 more he said he had no use for them and gave them to me. I got ahold of a few 350 legend cases. They cycle in my 351 so I loaded up 5. Put them in the mag and tried to cycle them and they worked. So I’ll fire them when the weather breaks. I’m resizing .357 to .351. The ogive is off from factory so I have to seat them further. Currently the load is 17 grains of IMR 4227.

Another tid bit for measuring purposes. Rims are same .38 Super, 35SL and .351SL. I've made alot of 35SL from 38 special brass. 9mm Lee carbide dies work just fine for me. YMMV

[No3steel]

I just started reloading mainly for the 351. I’ve been reading everything I can find on reloading it. This is the first time I remember seeing about the 38 super. 9mm to resize the case? Being retired this is a good way to keep me busy.

I joined this group to answer questions on the .351 some years ago.

I just trim .223 or .350 legend cases to length my gun runs the rimless version very well .
There is a slight difference between .223 & .350 L cases the base of the case is .02" wider on the .350 L . It does not seem to harm a thing as the .223 case holds the pressure well . The trimmed .350 cases have a slightly lower case capacity then a .223 case .
I do have 351 WSL load dies but normally use .357 magnum dies to load EXCEPT I use a universal case belling die to expand the case neck. I also use a Lee Factory crimp die to set the crimp .
Bullets either cast or jacketed can be sized with a push though sizer and the right lube (case lube works) If you get you peak leverage point set correctly .I have also found a one ton arbor press has Enough push to size a .357 jacketed bullet to .351" .

I tried to get the Hornady 140 grain FTX (SIZED AT .351") to shoot well in the .351 WSL using little gun I did get them to 2000 f/s but accuracy was poor . The 140 FTX is the same length as the original Winchester 180 grain bullet so powder capacity is not great .
I have gotten the Speer 160 half jacket the Sierra 170 JHC and a cast 162 grain Lyman Semi wadcutter to shoot well . Often I find top end .357 Magnum reloading data works well as starting point only small rifle primer is used not small pistol primer .

BUFFER !!! You really need to see if the buffer in your gun is good mine (1916) was toast There are posts here on this and how to check it . Some 5/16" (8mm) steel rod is needed to get gun back together.
The buffer is .67" across with a 5/16" hole in it I forget the original length but made a new one at .4" and it works well (.376" may be the factory new one if you can find one ) . I cut up a rubber hammer for material it seems to work well and I do not feel a sharp recoil like before which can crack the receiver.
You can find more on other posts and if you would like P.M. Me .
