I just had my CZ550 9.3x62 rechambered to a 64. It has a 20.5" barrel and i will be shooting 286 Nosler Partions from RWS brass. Any help would be great as i need to get this sorted out and continue work on two other rifles. Thanks!

I've searched here but didn't see much data.

Hi,
unfortunantely, I wonder if you will get much more velocity from that short 20.5" barrel than you got with the original 9,3x62 chambering.

But I might be wrong

Where did you find brass?

I stick with IMR 4320. snowman, has done far more loads, he's even made brass from .458 Win. I'm sure he'll be happy to help.

Nosler has loads listed in their latest manual.

I don't have my 9.3x64 back from the stockmaker yet and haven't done any load work.

But I plan on having three loads.
250gr TSX
250gr Banded solid
250gr Accubond

I also have some factory RWS ammo coming in 232 and 293gr weights.

If I ever get the Afica Cape Buffalo thing worked out, then I may work up some 286gr loads.

JimD, i found it at Natchez shooters supply a couple months ago on sale for $17 a box so i bought 5 boxes. I should be set for awile.
