Right on. I have the 3rd, 6th, and 12th editions. Load data is generally sparse, but a good starting point. I do wish that their measurement chapter included water capacities.

Good info. My FN Supreme 7X57 has excessive headspace. I hadn't used it in so long that I forgot that and was puzzled by cratered primers that were still rounded with what should have been mild loads. I imagined a too long firing pin, among other unlikely scenarios. Gunsmith checked...

My 20-inch barreled 9X57 is well suited to that. Frankly, I am more a theoretical hunter than an actual one. Several hunting rifles but few hunting outings. My pathetic collection of antlers is meager at best.

An avid Jack O'Connor fan back in the day, it struck me that the .256 Newton probably had a similar bore capacity to the .270 Winchester, which Jack claimed to be ideal. It very much seemed to me to be a cartridge that shouldn't have died. In the early '70's, I had to pass on a $220 Buffalo...

I'm not sure what it indicates, but with the Kapok wad in place, I was seeing velocities at the low end. Others have mentioned velocity gains. I plan to single load from now on. Shooting 139 grain bullets at 2100 fps is very pleasant. I got a one pound bag from Bean Products via Amazon. I...

Kapok is a natural fiber, so it isn't going to melt like synthetics are alleged to do. I've just begun tamping 1 grain of Kapok over a half-case of powder for an 8X60S Mauser. I noticed single digit velocity ES until the last round in the magazine. My guess is that recoil eventually dislodged...

The 1914 M98 Oberndorf Sporter's barrel is marked "9,0 H." From what I hear, that indicates 9X57 Haenel. The thing slugs 0.358", so I'm set to use US 35 cal projectiles.

The barrel slugs 0.349/0.358" 6R rifling The 9X57 ammo I bought from Buffalo Arms has 0.356 bullets. I'll be able to reload it with U.S. 35 caliber bullets. They used 35 Whelen cases, shortened. I use 8X57 PPU brass. Once through the sizing die (& expander ball) and, presto, I have 9X57...

I am using PPU 8X57 brass and I bought some 9.3X57 Norma brass (!) at Sportsmans Warehouse. Both work fine for 9X57. My 1895 has a .358" barrel. I don't know yet about the Mauser sporter's barrel, which I haven't laid hands on yet. The 1895 has a receiver sight. I'm looking forward to...

Funny, but my 256 Newton was rebarreled from a Ruger 77 in 257 Roberts Ackley Improved that I got at Cabela's in Lone Tree, CO.

Okay. Please PM me (assuming that's a thing on this forum).

Are you willing to counteroffer?

Hell of a dust storm, that!

9X57 factory ammo is not a thing I expect to find. I do have some new 9.3X57 Norma brass to establish a starting point, but I'm stuck guessing at the meaning of the expansion numbers.

I'll try to tread cautiously. I have not read P.O. Ackley, so was not aware of any extreme tendencies, but I suppose his hot-rodded wildcat cartridges should have given me a clue. I have had one experience with feeding issues from a 7X57 magazine with 358 Win ammo. Every once in a while, the...
