Well, Since 8mm Mauser Boxer Primed Brass... - The Firearms Forum

gandog56 · 05-25-2009, 03:33 PM

...is hard to come by, I converted some 30.06 brass to 8mm. Just ran it through a 8mm Mauser full length sizer die and trimmed the case length down to specs. Shot at 50 yards and iron sights on my K98. (The flyer was a 7.62X54R from sighting in a new scope on a Mosin Nagant)

Sweet, I have often wondered it that would work. Nice work Gan...

I have been doing this for a number of years now. Since about 1979 actually.
I shoot far more wheel-weight cast gas checked lead bullets than jacketed.
My loads in .30-06 converted cases are as follows:

1. 170 grain gas checked Flat Nose 100 yard target and small game loads get 1550 f.p.s. with 16 grains of Alliant #2400.

2. The same bullet for a 250 yard deer/target load gets 2056 f.p.s. with 29 grains of Alliant RL-7.

The pressures are really low, and the accuracy is exceptional in both of my Yugo M-48 rifles.

Nah, I like max velocity jacketed loads.

Deacon · 07-18-2009, 09:01 PM

In that case, you might want to try my jacketed bullet load.
This load is made on reformed Winchester .30-06 brass and pressures are fine in both of my guns but remember to work it up in yours.

Hornady #3232 150 grain SP Winchester WLR primer AA 2520 @ 52.5 grains.

M-48A = 3022 fps

M-48 = 3005 fps

Well, seeing as I just (and finally!) got 8 pounds of IMR4895, it would be a while before I try AA.

Hank45 · 08-05-2009, 05:41 AM

Does any one know what the original bullet (head) weight of the 8x57 that was issued to the troops was? Was it 150 - 196 - 220 grain? Thanks for your answer Hank

Hank45 · 08-05-2009, 05:44 AM

Sorry I forgot to put the correct cartridge number It was the bullet for the 8x57SJ Hank

Snakedriver · 08-05-2009, 07:09 AM

I'm pretty sure for 8mm it was the 196 gr. bullet. Mausers excel in accuracy with heavier bullets.

I use 160's and 175's in my 7mm Mauser.

Edit: Well I was wrong, I researched it a little and as it turns out the original round was a 227 gr. bullet, but in 1905 the "JS" was introduced as the standard bullet using a 150 gr. projectile. The bullet diameter also was increased from .318 to .323 in the "JS". Sorry about the wrong info. in my original post.

Hank45 · 08-05-2009, 10:32 AM

To Snakedriver, thanks for geting back to me. The reason I wanted to know the weight of the bullet is that I like to start at the original bullet and then build up to what works the best in my particular rifle. Thanks again Hold center Hank

hank, you can figure out what your rifle will shoot best simply by measuring your barrels rate of twist. Then a few simple math problems using the greenhill formula and you will be able to find out the biggest bullet your rifle will shoot accurately.
