250 GN 30 caliber bullets.....Loading data???

[98src]

I have 100 250 grain 30 caliber BTHP bullets. I think they were for an experimental target load developed in the late 50's. Anyone have any loading data?250 GR 30 cal (1024x751).jpg

308 or 30-06?

308 or 30-06?

or 300 H&H or 300 Magnum?

or 300 H&H or 300 Magnum?

Those too. We're probably forgetting a few.

we are,

I checked my Dunlap's manual, and for all the calibers so far mentioned he used a max size of 200 gr,

Yep.....i couldn't find anything in my reloading manuals either. I bought from the same man a box of the WESTERN 200 grain 308 Match "Hand loaded" cartridges with mercuric corrosive primers. These were loaded, IIRC, for the bolt action target rifles and I think they had to be single loaded308 match-1 (1024x752).jpg308 match-2 (1024x768).jpg308 match-3 (1024x768).jpg

Probably 300 H&H.

I have a single example of a 30 cal (.308 dia) SP bullet the at 330 grs ! Someone told
me the firearm factories used these bullets in test loadings to check recoil ? Also read
that years ago there was a custom 30 cal 250 gr bullet available for hunting in Africa.

Also have a photo of a NM 7,62mm cartridge with 200gr bullet, it is on the right side of
the white tip "low recoil" 7,62mm developed for Viet Nam troops.

The 200 gr NM 7,62mm would not fit in the M14 mag and had to be single loaded.P1010042_0038_038.jpgP1010043_0039_039.jpgP1010010_0010.jpg

Probably 300 H&H.

I'll try to remember to look in a couple older lyman/ideal manuals I have,
they may show a cast boolit load, that can be used to extrapolate a starting load,

would be interesting to see how they do...



BTW, if you want a scanned copy of that Dunlap manual, shoot me an email (email in profile)

The Lyman Reloading Handbook 43rd Edition has 30 cal 250gr jacket reloading data for 300 H&H

powders used are 4320, 4350, 4831 and H570

velocity was between 2100 to 2200 fps

RCS,
Thanks for the "heads up". I think some of the early M70 target rifles were chambered in 300 H&H.
