I just traded for an 8x57 rifle.
I was shopping for dies and found that RCBS makes a die to form the 8x57 from 30'06 brass. Imagine my excitement as I have 500 pieces of brass and no more '06.
I will be loading for a Mauser 98/22, where is a good place to start with powder and bullets?
I have in house IMR 4350,4064,4895 and RL 19, BLC2, W760.

I'm just going to be punching paper if it matters.
Is this a relatively easy case to load for?
Why no data on the loading page?

8x57 is easy to load for, all of those powders are excellent in 8x57. Never formed brass from 06, I just buy bulk winchester. 4064 and 4895 will be real easy to find an accurate load. I use 48gr's of 4064 with a 170gr Speer.

Loading for it is pretty sraightforward once you get past the whole bore diameter issue and load to European specs. Maybe start with 150gr bullets and see what happens. Finding loads for some of the heavier bullets can be tricky. I have some load data if you're interested. Also, IMR 4064 is the ticket for the 8x57.

Someone said the 8mm is like a big .223, perfect.

I have sized and trimmed '06 cases for the 8x57. It is a good way to save money if you got a bunch of '06 brass laying around. Trimming is very time consuming and there will be a lot of brass shavings. Then there is the thick neck thing too. The military stuff will need to have the primer pocket reamed cuz the primers are crimped. I found that spending the money for some new headstamped 8x57 brass was well worth the money. Now I Save that '06 brass for my 338-06. I tossed all that military crap too. There is just sooo much once fired R-P '06 brass laying around the range after the deer rifle sight in. I pick up several hundred every year.

There is a danger involved in making 8x57's from 30/06 brass. Some 30/06 chambers (Springfield, win 95's ect)
will accept an 8mm. Someone will put it in the gun it's headstamp says. The danger isn't the oversized bullet.
The neck, shoulder junction of the chamber holds the bullet in the case.
Brass for these guns is so plentiful, why risk it.
Good luck!

The danger irv is speaking of exists only if a novice gets a hold of some of your loaded ammo and tries to fire it in their '06. I believe irv is speaking from personal fears rather than logical thinking.

You may deny the risk but the reason that Winchester stopped making the Mod 95 was that
Too many "Novices" blew them up with 8mm ammo. Go ahead it will only improve the gene pool.

I've never fired an 8 x 57 with anything other than reformed '06 brass, and I've never owned any special "forming" dies, either. It's silly-simple to run '06 through an 8x57 FL die, then trim to the right length. As a previous poster noted, you may sometimes get wrinkles at the shoulder if you don't keep your lube to a minimum, but any inadvertant wrinkles iron out on the first shot. It would be an unusual lot of brass or an unusually tight chamber neck that would require neck thinning of re-formed '06 brass.

One of the advantages of getting older is that it's too much of a strain on your eyes to read headstamps. This can keep you out of a lot of trouble. Even poor eyes can see the difference between the length and profile of an 8x57 and a .30-06 cartridge; besides, if I had an '06 with a chamber so sloppy that it would accept an 8x57 cartridge, it would be long gone from my ownership.

MLC, I shoot 4 different 8mm's and all with resized 06 brass. All my 06 brass are once fired from my local range. Couple of things: you don't need special sizers - any 8mm sizer will do, better to trim back the longer 06 brass before you run it through the 8mm sizer or else the longer case will go up into the resizer die and "bugger up" the case mouth, 4064 and 4350 powders are the most accurate, most 8mm's are more accurate with the heavier 175-180 grain bullets rather than the 150's. I don't see how a 32 caliber 8mm mauser case can be chambered into a 30 caliber 06 - I know the 06 is longer but when I tried this the larger diameter bullet prevented the 8mm round from chambering ..Gary D.

The neck diameter of a .30-06 chamber would have to be at least .020 oversize to allow the 8X57 to enter the chamber far enough to close the bolt.

This dimensional error is extremely unlikely and the ability to crush the 8 x 57 round .020 in diameter for about 1/8" of length is also something that is extremely unlikely.

I'd downplay the potential of shooting a 8 X 57 in an '06 chamber.
