You will need to reload with the same size Berdan primer, and there are alot of diff. sizes, hard to find most sizes. I would shoot the shells and throw them out, buy new boxer primed empties. I would only mess with Berdan if you can not get or make cases any other way.
 
I know for different size for primer,
My question is :
I have to make Berdan Primer or Classic Primer Is Ok,
I want to be sure if I put classic primer on the brass no Accident for me
I newbie in reload
thank you
 
Boxer Primers cannot be seated in a case designed for Berdan primers. The anvil is built into the case in the Berdan system, and it has 2-4 very small flash holes, whereas the Boxer system incorporates the anvil into the primer itself, and the case has only one central flash hole. Additionally, Berdan primers come in several diameters, none of which correspond to the boxer LR size of .210" or the Boxer SR of .175" Regards, Eagleye.
 
Pick up some 30-06 brass. Cut a 1/4 in off and use your 8mm dies to reform them. They will work quite satisfactory for you.

Works great but what a PITA it is.

Did you have the exact size I need to cut Please

Easiest way was first expand the neck but don't reform the brass. Then use a Lee Case Lenght Gauge and Cutter. Put in an electric drill (drill press works even better) and cut down. Reform brass and re-cut to the proper lenght.

You will eventually break off the threads on the gauge but they are only $8 at Higginsons.

I've got a few hundred done this way and they work great. But as mentioned was a major PITA to get to the point to shoot them.
 
Buy some new 8mm brass or some once fired. It is available. You can also buy 7x57 mauser brass and expand the neck.

Reloading berdan is only done if the brass is not available withthe Boxer (Classic) primer. 8 mauser is available.
 
You can also buy 7x57 mauser brass and expand the neck.

This you cannot do safely!!! :eek: The Headspace dimension for the 7x57 is considerably shorter than that of the 8x57, and will get you into serious trouble, quick. To use 7x57 brass, you would first have to expand to at least 35 cal, and then neck properly in an 8x57 die, leaving a new shoulder to headspace on. Regards, Eagleye.
 
8x57 Brass

.
I just checked the Wholesale Sports Catalog. Bulk Remington 8x57 brass is only $2 more for a bag of 50 than a the same amount of 30-06 brass.

You can buy 100 Remington or Winchester 8x57 brass, reloadable, for only four bucks more than the 30-06. Therefore, is it worth the PITA to go through the hassle of cutting and trimming the 30-06? Also, when you trim the longer 30-06 brass, you end up with thicker case mouths, and possibly a pressure problem, unless you ream them.

The $4 extra you spend on the correct brass would certainly be a lot less than the more expensive cost of Berdan primers and a RCBS Berdan Priming Tool was about $60 last time I looked.

With the more common cases, it it a lot easier to buy the correct ones and reload with Boxer primers. It is a different story if you have some exotic calibre that takes an odd or almost non-existant case. Sometimes you HAVE to use a Berdan primered case so that you can fire your rifle.

Another thought. Were the 8mm cases you used and want to reprime, are they older Military loads? If so, there is a good chance that they are corrosive primered loads. If they are, you really have to wash out the inside of the brass.

Reloading berdan primed brass is more trouble and expenseive than it's worth. 8mm Mauser brass isn't terribly expensive nor difficult to get.

Yes, sorry. I should have said more. It came to mind because I just did this because I had a pile of 7x57 brass and needed some 8mm. I seated the bullets long and shoved them firm into the rifling, to control the headspace.

Don't foregt poor headspace due to ammo is not a problem. Not the same as a shallow chamber causing headspace.
