Hi ,
I of course agree.
9.5x52R makes much more sense to me,as noted in my last post.
Considering your chamber cast dims. I wonder why Husqvarna used the 57R designation in the first place.Other than that they loaded .366 bullets,not .375  into the 57R case as I mentioned earlier.
Also as mentioned,I recon it shot poorly and they changed the barrel dims to suit the .366 bullets.And never mentioned it.
Has anyone seen/got an original 9.3x57R cartridge?
does anyone now when the change over happened?
The mystery deepens!!
Sure would be nice to get hold of an original round from both eras to compare.

40-65tom's 22xxx rifle "lettered" to 1889 so that is probably too early to say the bore size was reduced for smokeless. I suppose another alternative would be a short case with a heeled bullet. This almost looks like one:

I just dropped in at the Husqvarna page to see about contacting them about dating my gun. I found something very interesting I hadn't seen before! They offered the Type 33 in 9.5x47R!! This would explain the .375" bore at least. But 47mm is 1.85", which is shorter than my chamber.

Yes, the 9.5x47 is bottleneck, and also shorter. Different chambering. But it makes me wonder if some of those 9.5 bore barrels got chambered with a different reamer? I just ran a bore scope down my Husky to see if the chamber looked altered in any way, and it all looks old and original. Still puzzled what I've got, but not unhappy with how it shoots, and that I can use .38-55 and .376" bullets.

Hi,
Barrel refreshing! Now that is something that never occurred to me.
Both of the guns that have the .375 barrels are lower serial #'s than the .366 guns.
The re-cutting of the  rifleing to a bigger calibre is of course a common solution to worn out barrels, and I assume cheaper than sleeving.
I think you may have solved the problem!!

Hi all,
An update on reloading the 9.3x57R.
You will recall that my Husky has a 9.50mm barrel rather than the 9.30mm.
Whilst waiting for the dies, mould etc to arrive from the US to the UK,I decided to convert some 30/30 Win cases to accept .375'' bullets that I have that were used in my Win 1886 38-56. They are aprox 250 grains from an NEI mould 4 cavity.
Basically making slightly shorter 38-55 Win cartridges.
I annealed the neck and shoulder area of 22 cases and then had to file down the dia. of the rims as they are to large to chamber. Took some time!!!!!!!Still, being retired I have loads of time to waste.
Next, try and enlarge the case mouth to accept the bullets. After wrecking 11 cases trying various combinations of expander buttons, I decides to use drill bit shanks in 0.50mm increments from 7.50-9.00mm by lightly hammering the cases over the lubed shanks with a leather head mallet. Worked great.
I now had 11 cases and decided to trim them to 50.00mm o/l to make them all uniform.
After much consultation of loading manuals and cartridges of the world I decide on a reduced load of 13.60 grains of 4198 powder,as that was a convenient lee dipper spoon at around the load I had decided on. Didn't fancy messing around changing out my Dillon measure for 11 cases.
Successfully loaded the cases and finished up with custom 9.5x50R rounds!!
Went to the range Saturday, only 25 metres pistol range that my club was using that day for a 3 gun Western Match, and shot the rolling block offhand in the lunch break at some bits and bobs, old 12 bore cases and the like. And three of us hit every thing we aimed at. It was spot on using the fixed leaf of the 3 leaf rear sight. Excellent. Very light load, felt like a 44/40 in a Win 92 rifle.
Not much of a test of the ol'girl I know. but the nearest rifle range is 48 miles/two and half hours away across to the other side of London. Perhaps I'll get to it one day.
The cases fire formed perfectly as well.
The mould arrived last Thursday, and the dies Friday. So now to start reloading proper 9.30x57R cartridges with 9.30m bullets and se how much I can lead up the barrel.
More to come!!!
Regards 
Geoff.

Sounds like you made a good choice in sights! Those are good groups for the first effort with better sights! I still haven't figured out which sights I might put on mine.
