Old Data Needed

padd54 · Posted: Wed Dec 31, 2008 12:17 pm Post subject: Old Data Needed

Greetings all,

I am trying to work up a load for my 256win mag. I have a 117g round nose that I hope to work up a load for deer.
The only data I can find is limited to 60g, 75g and 87g bullets.

If someone out there has some old reloading manuals from the 60's I am hoping they would have more data.
If not, where would be a good place to locate some of the old manuals?

Thanks,
Ray

.256Win mag? It was fist revolver cartridge. .357 Mag case neced down to .257 bullet. Twist 14". 117gr g
bullet shall to keyholes! Or do you have custom made barrel for T/C or some rifle like Marlin lever action rifle?
I think, you cant to find reloading data for 117 gr bullet for this obsolute caliber. The heavist bullet, I think is 87gr. I can also to be wrong?

Thanks KW,

I have a Marlin Model 62 and I have dies to convert 357mag cases to 256win mag.

I am going to stick with the 87gr bullets. It was just an idea.

Thanks again,
Ray

I did some quick math and I think it would end up under 2000 fps. If that were the case you might find some cast lead loads that would work a la 30-40 krag. if your sticking w\87g's did anyone ever use aa1680 , I would think for velocity sake that may be it. it sure soups up the old .218 bee w\ 35g's

Padd, a friend here shoots a .25-06 for deer and hogs, I'll ask him if he's interested in the bullets. Give me an idea what you want for them.

I consulted a 1970 sierra and ackley's volume 2 and cart o the world 11thed nothing sorry. I remember seeing some cast lead loads in an old hodgdon manual if you ever get a flare up of that bug again. this disease sometimes reoccurs at odd times like at relatives weddings, long sermons. etc. anytime the mind seeks refuge from boredom.

Padd54, I looked in my manuals. No load data for 117gr slug for 256 win mag..They did list the 117 for a 25-35. It is a low pressure cart w/max of 38,000cups. The max cup for the 256 win mag is 43,000cups. If you have a chrony, I would use the start load for the 25-35 minus 2gr.then work up from there. The max mv for the 25-35 /w 117gr slug was 2200fps..The book says the 256 win mag is just a little faster than a 25-20..If ya want my data, email me or pm me...Hope this is helpfull...Dave

Thanks fireball,

I do have a chrony and will take you up on your offer.

I may just as well try a few loads and see what I can get.

Do you all think "nickel plated" cases would help with an increase of pressure?

Thanks again,
Ray

Very cool little cartridge! I had a TC contender barrel in this caliber but sold it for what ever reason...I cant remember.
Good luck with this adventure.

I an finding that the spire points won't allow me to stay within the max OAL.

Right now I am content with the 60g FN that I have found. But will keep looking for a little heavier bullet that I can use. I am hoping to find an 80-87g bullet that will aloww me to stay within the max OAL.

Thanks again for all the great responses.
