These are great rifles. One of the best kept secrets in the rifle/shooting/collecting world. I have two; one in 8x57 and one in 9.3x57. Mine are both commercially made Husqvarnas on the 96 Swedish Mauser action, models 640 or 648 or 46, I can't remember. One of the above model numbers is actually the 98 action, I believe, but I'm not sure which. Anyway, I can't tell you anything about the serial numbers, but these guns are very nice, smooth, strong, well made and accurate rifles. Swedish steel is among the strongest steel. And they are usually very reasonably priced. As far as ammo goes, I make it from 8x57 brass. Just run the 8x57 brass through the 9.3x57 full length sizing die, and presto, instant 9.3x57 brass. There are several web sites that have some reloading data for it. So, if you don't reload, finding ammo can be a problem. I think Normas still loads some, but it probably is not cheap.
If jpattersonnh would chime in here, I believe he can offer more info than I can.
Were to start!!! I love 'em. I bought my son a M46(1932) I have a M46a(1943).
Both are 9.3x57. Ammo is expensive if you don't hand load. My 46a hated 232gr Norma, my sons did fine. Now 285gr gas checked cast lead or 286gr partitions are awesome. 270gr speer are also excellent. I load over IMR4064. There is quite a bit of data as Cotton said, but for 3031. I love the 23" barrel, light weight and the bone crusher it is. Yours should have express sights. They are sighted for 150 yards. Your only about 2" high at 100 so it really makes no difference. The actions on the ones we have are as smooth as glass. As Cotton also said Swedish steel is among the strongest, even by todays standards. In its' day nothing came close. Even the Oberndorf M96's that were made were from Swedish supplied steel.
Thanks guys for the info. I inherited my husky from my father. It came from his uncle who I am named for. Unfortunately I don't do my own reloading. I guess trying to find ammo will be tough. All I want to do is fire it a few times. Maybe I should think about starting to do reloading. Hopefully I will find some at some gun shows. Do you know of any places i could try to find ammo from. Thanks.
