Just thought some would like to know. I recently re-barreled a post-'68,CRF M70 to 9.3x64. The rifle was originally a .270. Modifications were limited to opening up the bolt face and adjusting the extractor hook. No work necessary for good feeding. An easy conversion!

Nice.

Thanks for the info! If that is the case, then I imagine one might get similar results converting to 10.75x68. Mmmmm....

Yep very nice cartridge. It was designed for a M98 so it will fit a lot of actions with a minimum of fuss.

I will be building one soon, already have a Oberndorf M98 and a Shilen barrel.

The barrel below, it is 29 inches long. I will have a reamer ground with a long throat so the long 9.3 bullets may be seated with the bullet base at the shoulder/neck junction, where they should be and not in the powder space. Rifle will be built "Cape Rifle Style", long barrel, iron sights and the stock correctly configured for a good sight picture.

The barrel below: The one in front is a 338 25 inches long.

Should be no problem. Could possibly even use a magnum magazine box/ follower to get an extra round in

FYI I get great service out of RWS brass in 9.3 x 64mm. Huntington's gets that in every four to six months. Simply awesome brass.

The 9.3x64 deserves to be more popular than it is. Flat shooting and powerful. The selection of bullets is improving. Barnes, Nosler,Speer,Swift along with a few imports like Norma,Woodliegh and Privi. As mentioned RWS brass is superb and Jamison and Quality cartridge now list it as well. In a pinch it can be made from 338 brass as well if you have a small lathe.

And my take is that it is offers little practical advantage over the 62 (maybe 150 fps), and yet introduces logistics issues along with it.
Not to disuade anyone from it.

Minor logistical issues aside, the 9.3X64 is arguably the best single cartridge to hunt the world. Even the really big stuff is doable with 300 grain solids.

I own quite a few nice rifles but particular 404, 9.3X64 and 270 rifles are the three rifles that will stay with me until the bitter end.

Forrest i agree with the 404, 9.3 x 64, instead of 270 i would go with my 270 Weatherby or my 7mm-08, probably 7mm-08. You've shot a lot of different calibers, so i listen to what you say.

Tom, i have a 9,3 x 66 as designed by Erkki Kaupi, the ballistician of Sako. It gives the 9.3 x 62 the oomph it should have had from the get go.

The 9.3x66 should have been a 9.5.

Such a creature already exists.

A better version is the 376 Steyr. love mine!

You would be better off getting a 300 Rem Ultra mag action and just putting a 404 Jeffery barrel on. Much easier.

A 10.75X68 may need more work on the action.
