Husky 9.3 x 57 mm to 9.3x62mm

I'd go one better and go to 9.3 x 64

The 64 will need mag modifacations. But the first thing is there enough meat in the barrel to support the high pressure cartridge.

When I spoke to Ralf about going to the brenneke chambering he advised against it. The 62 was designed to run in similar pressure to the 57 case.

The 64 Brenneke runs a fair bit higher pressure. Of course it depends on the barrel. The rifle I wanted to do this too was a Husky 146. The barrel tapers down not far ahead of the reciever and therefore would not have enough "meat" to withstand the Brenneke.

As fun as it would be, the brass is harder to find for the 64 and more expensive. Having played with the 57 and 62 so far I wouldn't be afraid to go back to a 57. A 250gr bullet at 2500fps is nothing to sneeze at.:cool:
 
Hopefully Pete stops by to let us know what he has for a reciever. The X62 should fit the mag box but no guarantees with three plus different mauser actions, if his is even a 98 action.....

Republic's COL for example sure won't fit a standard mag. Bummer.
 
R of A, what action do you have? The longest COL I can manage to feed reliably is 3.270" with an M98 Husquvarna in 9.3x57 and 250gr TSX. I thought about rechambering as well, but the bullet base is already right at the shoulder so powder capacity increase would be minimal. Looking at you COL compared to one of my reloads though, it looks like you could likely get in an extra grain or more of powder without much trouble.

One challenge is the Barnes Bullets are much longer. You will gain a bunch more space just by using a conventional jacketed bullet.
 
I have looked at what you have all stated, and with the data on the 9.3x57 vs the 9.3x62. There isn't that much of a gain. Cost would be too high and frankly there are a few rifles out there already in this caliber.

BTW the rifle I have is a model 46? possibley a 146 Husky.

I compared the 250 TSX to the 250 Nosler Accu-bond at Epps a few weeks ago and the Accu-bond was nearly an 1/8" longer than the TSX. I didn't think to compare them to the 270 Speers or the 286 Partitions while I was there, maybe next time. I don't think they had any others in stock at the time except the 286 TSX.

I think it is a Husky, done up by Martini and Haggen. I bought it used off the board and don't know much about it.



The discontinuation of the 250g Ballistic tip chaps my ass. I haven't used it but it may be one that I really like as it has the qualities I look for in a bear bullet. Lucky I bought one box and can try them out, to bad I wont be able to get more. There is always the 270g Speer for that sort of thing I guess.:D

Will try the 250g Accubond as a replacement for the 286g Partitions. I cannot imagine it not penetrating deep enough for the game I shoot around here.
 
Republic,
I tried to read up on the ballistic tip you mention, it was liked by alot of folks. I never got any to try, to late joining the nine-three club.

FWIW the 250gr Accubond has near identical attributes as well as a cannelure. It has held up well in the basic tests performed, going as deep as the 270gr Speer everytime. They make a great balance of big power and yet give a trajectory that is better suited to the open country.

The new Hornady will be fun to try as well.
