8 X 57 mm plain base

[KHornet]

The 06 once fired that I formed was from RP brass, and opening it up from 30 to 32 just thinned out the necks a bit. Great brass. Think I will form only from Rem brass. I also have been partial to Lovern molds. Don't have many but those I have are all shooters. Know it is a waste of lube some times, but I like to fill all of the grooves, looks cool with hard red or blue lube.

Ben,
That sounds about what mine came in at...I guess I got carried away while neck turning. I haven't had to do it in years and just jumped right in without a constant check.
Learned a good lesson the hard way! Also the cases were freshly annealed so the necks cut like butter...easy to go to far.

I have a few different batches of RP commercial 8 mm brass Some are marked "8 m/m maus" and some marked "8mm(8x57)"
The only thing I find strange is that they all are short in the neck (case length about 2.22") The neck thickness is .012"

IMO, the expansion of commercial 06 brass to 8x57 (Rem or Win) thins the dia a bit to the point where it is just about perfect. That said, I formed a couple from LC brass, loaded them as dummies with .325's and they would not chamber in my rifle. Might have with .323's, but as I know I have no problem with the commercial Rem or Win brass, will stick with that and not have to mess with neck thickness.

KHornet,
Yes I have found the same thing. Reforming commercial 06 brass to 8 mm; no need to touch the neck afterwards…at least not the R-P, Win, and Fed cases I have reformed.
But I think that old military brass is thicker in the neck to start with.
However it will chamber in my GEW98 but it has a tendency to squash down my PB boolits ( probably more spring back after neck sizing & expanding because of the extra thickness.)
Was trying to get the whole batch closer to the commercial neck thickness ….unfortunately I overshot the mark. Fortunately they work great for light PB loads

I had some 30-06 military cases that had been reformed to 8 X 57 mm.
That brass had a lot of cases with thick necks ( up to and including .017 " )
I " outside " neck turn my brass.
I ordered a Hornady , 8 mm mandrel for my Hornady Neck Turning Tool.
Today , I turned my military necks to .012 " which is similar or identical to my R-P, 8 X 57 mm , commercial brass neck thicknesses.



They chamber smoothly now . ( With .017" thick necks, they chambered hard ).
As we all know the bullet in any cartridge has to have " release " . With the thick necks on my military brass , I didn't have that, so I would not fire them in that condition until the necks had been thinned to offer me the needed " release " that is necessary for safety.

My load to test these will be :

8 X 57 mm brass from reformed military 30-06 brass.
250 gr. NOE plain base 327331 RN cast bullets
Cast bullets sized to .325 "
Powder charge will be 8.5 grs. of International.

Pretty easy to see the necks where they have been turned.
They are uniform now.

Ben,
That is a great neck turning tool! I just have the attachment for the Lyman Trimmer machine (Not really precise) now that is a nice trim job! I believe I still can see the 06 neck shoulder junction on yours....I think my mistake was I used that as a basis for max trim thickness that is why I got down to .009"
Those missiles look awesome! What speed do you think that load of International will make?

I got some new stuff to write about but I have to wait until later today I'm cooking & doing chores right now. I think I did some good shooting this morning
I will report soon!
Thanks for posting your progress

Speed.........I'm thinking about 1,000 fps or maybe 1,050 ? ?
Like Brad said in another post, slow to get up to speed and it will be slow getting it stopped.

250 grains of anything at over 1,000 fps is a killer.

Don't recognize the headstamp PS74. Who made that brass?

 

[JWFilips]

I found these listings"
PS Giulio Fiocchi S.p.A., Lecco, Italy
PS Pirotecnia Militar de Sevilla, Sevilla, Spain
PS Poongsan Metal Manufacturing Company Ltd., Seoul, Republic of Korea (probably at the Angang Ammunition Plant)
PS Povázské Strojárne, Povázská Bystrica, Czechoslovakia (now Slovakia

Jim,

Here is an NOE, 326407 , 8 mm , Plain base, Loverine that I'm experimenting with right now.
So far, so good.
These have the bottom 4 lube rings filled with Ben's Red and then the cast bullets are rolled in BLL. Bullets are sized .325 ".

 

[KHornet]

Thanks JW

 

[kenneth]

hello. i'm the new guy here. i'm curius how this experiment goes?
i have an old german civilian hunting mauser m.98 and i'm trying out the heavy 8mm lee mould. before i tried out a lyman168gr. rn. that worked ok but i like the heavier bullets.
Thanks for a nice forum. i think i like it here!

 

[Ben]

Glad that you're here Kenneth ! !
I need to add that the " 407 " NOE you see above is 190 grs.

Ben

 

[kenneth]

thanks. this seems tho bee a friendly place !

 

[Ben]

Very friendly.

I've been on other cast bullet forums.
This one is the BEST in my opinion.

Ben

 

[kenneth]

i've been on the cast boolits of course and some other sites.
this seems to bee a most friendly place.
I might stay here.
did you have time to try out the noe 8mm boolit and did'it work out ok?
this is not my language and there might bee problems in spelling and such ....

 

[Ben]

Yes, I've shot the Loverine 8 mm plain base bullets you see in the photos above.
They are very accurate out of my 8 X 57mm.

 

[Ben]

this is not my language and there might bee problems in spelling and such ....

I'm not certain where you're located, but I think you are doing well with your spelling , etc.

Kenneth:
I have some testing to do on some heavy weight 8mm PB Bullets from both Ben and KHornet. Should be writing up some reports in January.... I will be firing them in my GEW 98 8 mm Open sights
I will add my results to this thread
Jim

 

[Ben]

This isn't with a plain base bullet , but the IDEAL / Lyman 323471 is really a shooter out of my 8X57mm Scout rifle :

The rifle barrel is free floated. The rifle has a Timmney Trigger set to 1 lb.
I really enjoy shooting this rifle.
