I've been piddling with a Husqvarna 146 for a number of years. Working loads, with available powders and such. I have been only interested in the heavier bullets 270 to 286 grn.
I have found powders such as IMR 3031, IMR 4895, IMR 4064,VARGET, N-140 and N-540 work so well.
This cartridge is so perfect for woods hunters.
In a pinch, it will dispatch the nastiest of critters.
The number doesn't do a job on your shoulder, but crumbles big game within its range.
I must credit the Swedes for its design, eventhough, nobody really knows this perfect cartridges origin. It is a doll.
PM me for reloading data.

I thought for sure it was German origin, just preceeding the 9.3x62.

I had a commercial FN '98 action barreled with a new barrel, chambered in 9.3x57. I have shot it some, and it's as good as I expected. I haven't tested many different loads in it yet, but those I have tested, perhaps three, have all been very mild to shoot, and very accurate. It really is a fun cartridge. It was so easy to develop a load for that I haven't felt the need to experiment with it much. I just have it sighted in and a box of handloads on standby, ready to go hunting. I have a bunch of the Nosler 250gr Ballistic tips, which it shoots well, I think it would be great for deer and hogs out to 150yds or so with that bullet handloaded. It likes the Speer 270gr just as well.

I was fortunate enough to dump two deer this year with the 285 privi in a x57 , works just fine

I'm pretty sure it is a Swede design from the git-go. There were some early Husqvarna single shots and cape guns in a rimmed 360 caliber prior to the introduction of the 9.3 x 57. I believe they simply kept the .366 bullet diameter and put it in the x 57 case for ease of transition when they made the commercial Model 46 (their first commercial production bolt rifle). Although one would wonder why they didn't use the 6.5 x 55 case they were already producing.

The Germans had already produed the 9 x 57 and 9.5 x 57.

It was listed in the Mauser catalog long before Husqvarna listed it.

I tend to think if it was a Swedish development it would have been derived from the 6.5x55 case like the 8x54 KJ was.

No matter who made or designed it, it is a super little round. And the little Husqvarna rifles chambered in it are sweet.



It is especially nice in the smaller lighter M46.

Thanks for the library pic Mike. Love the looks of those two and will model my Peruvian off them.
