9.2 x 57 Husquvarna Sporter

[Ganderite]

The following are loads that I have worked up in my M96 9.3x57. All the brass is 8x57 Remington necked up in 1 pass through a Hornady die. All primers are WLR.

A note on H335- I have noticed increased pressure signs ,on loads in other calibers, developed at cooler temps when shot on hot summer days. It's not an "extreme" temp insensitive powder and is something to consider.

235gr Speer (.375 resized to .366) C.O.L.=3.005"
51gr H4895=2411fps
57gr H335=2566fps

250gr Accubond COL= 3.180"
51gr H4895=2358fps
52gr H335=2392fps
54gr R15=2316

270gr Hornady (.375 resized to .366) 3.166 COL
48.5gr H4895=2266
50gr R15=2152

286gr Hornady COL 3.166
47.5gr H4895=2173

Are those OAL based on bullet / lands? Or dictated by magazine length?

I think I will try developing a load with N150. I have a scoped M98 rifle and a M96 with irons. I will choose the most accurate load with the scope that does not have a pressure problem in the m96, so the ammo can be used in both.

With my old eyes, I will do the iron shooting at 50 yards.

N150 is too slow a powder for tha 9.3x57, even with the heavier bulets. My favourite load uses Leverevolution. I have achieved 2250;fps with a 286 Prvi bullet, with no pressure sign. That is in a M98 action ( Husky 146).

They are dictated by magazine length, except for the 235 loads. My notes indicate the 286gr COL of 3.166" is .228" from the lands.

Thanks. For sh!tz and giggles I will try both N140 and N150. I prefer to try a Viht powder because it happens to be the cheapest powder I have. N140 should about right.

Thank you. I load the M98 at 3.250" The M96 has a shorter box.

I have brass I made from 30-06 cases and I have 8x57 brass inbound, too. I guess I will use the 3-06 brass in the M96 and load the rounds shorter. The different brass will help keep track of which rifle the ammo is for.

I have a case of Berdan milsurp 8x57. I guess I could use that brass to make ammo for situations where I won't recover the brass.

N140 should be a good choice. BTW, beware that many of those rifles have long chambers. Often,, if you make brass from 8x57, you will get stretching and case head rupture after two firings. To avoid that, I make all my brass from 30-06, making sure that it is just short of a crush fit in my rifle’s chamber.

140 works pretty well, I have used in in both the 9.3x57 and 9.3x62. - dan

I always bed the old rifles (and most new ones, too). It may improve accuracy and will help maintain a zero from one day to another. Important for a hunting rifle.

Also, in older rifles, it re-establishes the recoil lug connection to reduce tang splitting.

I use Devcon F Putty. Very strong, easy to work with and low shrinkage. Some wood is removed so the Devcon has some depth.

The interior is also treated with some Tung oil, to protect wood when hunting in rain.

Nice bedding job. Great advice.

Good job on the bedding. Kudos. - dan

Looked rifle. Can't lower scope. Bolt barely clears now.

A gunsmith can bend that bolt down for you in order to accommodate lower rings.
