257 Robertsx6.5mm Arisaka Rounds ?

[DoctorBill]

Well that is the whole thing, isn't it ?

".....you just didn't notice it."

As one scientist said (I cannot remember who), "Everything, all of nature's
secrets and laws, are right there in front of your face for all to see.
Nothing is hidden - it is all there to be seen, you just have to look."

I guess I am not doing a very good job as a so called "scientist".
I get an "F" for the day !

You have me looking in all my Manuals now for 6.5mmx57 (Mauser).
I recall now that others had mentioned this round...

I have lots of data for 6.5mmx52, 54, and 55mm.

Nothing that I have has any 6.5mmx57 reloading data.

BUT - I have the SPEER Reloading Manual for Wildcat Cartridges"
No. 4 Edition.....1959.

..and it has data for the 6.5mm x 257 Roberts ! Holy Makeral !

I never considered that to be a "Wildcat Cartridge" !

It has data for the 87, 120 and 140 gr Speer Bullets
in 3031, 4064, 4198, 4320, 4350, 4831, 4895, HV-2, H380, H570 powders.

The rounds were fired in an M98 with a 24" barrel with Remington cases.

I do have 3031, 4064, 4198, and 4320.

The 4320, 4064 and the 3031 were recommended for the 140 gr.

I want to load with my box of LEE Cast GC'd 170 gr Cruise Missiles that
I have ready to go.

Has anyone reading this ever done that cast bullet in this round ?

Give me some suggestions.
How about 80% of the above min loads for 140 gr to start - with the 170 gr CM ?
Am I on the right track ?

I am going to try Trail Boss, that is for sure - anything else ?

Doctor Bill,

Sorry for sounding snotty in my last post. My reason was to get your attention, since you had referenced the 6.5 Arisaka load data a couple of times. We need to be looking at the right data, not just any data.

I have looked for a copy of the Wildcat Cartridge manual at every gunshow I have been to since I heard about it, with no luck.

I didn't think you sounded snotty, Mk42gunner.

I came upon the Wildcat Cartridge Manual from advertising on Craig's List
for "Wanted - Any and All Reloading Manuals".

I got quite a few responses - mostly from young guys who wanted to sell their
Dad's or Grandfather's Reloading 'stuff'.

The kids weren't into it, didn't know what it was, didn't care.....SAD.

So I now have several quite older Reloading and Shooting Manuals and some old CATALOGS.
Many smell musty from being in a box in the basement for a long time.

As you said - I looked right at it, but didn't "see" it....

If you are looking for any particular Wildcat data, I can scan it and PM
you with it.

I have a thread about that Wildcat Manual on this Forum.

http://castboolits.gunloads.com/show...5&postcount=26

I listed the 'Table of Contents'.

Several people have asked for particular Wildcat data - I sent it to them.

PS - Now with this shooting of the Senator and others in Arizona, watch all the
'Gun Control' freaks come out of the woodwork...especially the "American Media" !
and all the Hollywood hypocrites who make their living as 'Shoot-Em-Up' action stars,
but turn around and support gun control.

Has the world always been this crazy ? What is next ?

As young people, we all have done stuff that we regret later. Some of those young men will regret what they did later. By buying those manuals, you are helping them learn a lesson that will serve them well once they are old enough to know better.

So, in a way, you are doing them a favor!

I'll see if I can scan some loads for you. Give me a while, I haven't had the scanner set up in a dog's age.

In the mean time, don't be afraid to call Sierra's or Hornady's help line.

The world is definitely getting crazier.

A reprint of the spper 1959 manual is available from cornell publications.

Abby does great work. Just be careful as there are a lot of good reprints in her stock.

Have you folks been watching the Media about Conservative People ?

MSNBC (never watch it normally) is freaking out in an obviously orchestrated
performance - what Hypocrites and Liars.

I wonder who owns these major media outlets ?

The Left wants to squash our free speech - but just for Conservatives !

Thank God the November elections changed the composition of the House
and Senate. Who knows what travesties would have been passed in the
last couple of days by the previous regime.

I cannot believe what I am hearing and seeing !

Rabid. They want total control of everything. Like in Russia just before
the Bolshevik Revolution....

Old thread, but I wanted to throw my $.02 in.
Using 6mm Rem brass it only lasted 2 firing before getting close to having head separation. Because I own a 257 and a 7x57 I didn't want to use that brass. Going to 8x57, the headspace spec is longer so the brass is a bit tighter, and it kept the cases from stretching.
Set your die up to barely tap the shoulder if your headspace is on the long side.
Mine threw patterns with 120 gr bullets but with 140gr Core-Lokt 3 shots went into 5/8" with a 19" military barrel!

anybody looking at one of these it is not that hard to find jacketed data for.
hornady has it right in their manual.
compare that data to the 6.5X55 to get cast data.
