RVO-70 RELOADING POWDER
I have about 45 lbs. of RVO-70 powder (also known as HC30) that i purchas to reload for the 30/378 weatherby mag. that i no longer have.
I was told that RVO-70 is a very slow 50 cal. powder.
Is anyone familar with this powder and if it is to slow for the 300 weatherby mag.
(unale to get in touch with RIVER VALLEY ORDNANCE ITS DISTRIBUTOR FOR ANY INFO.)
THANKS FOR ANY REPLY

264 Thor. The Thor is a strongbelted case of good capacity, basically a necked-down, sharp-shouldered 8mm Remington Magnum. It gives impressive velocities - like 3700 fps with 100-grain bullets, up to 3500 using 120-grainers, and almost 3400 with 140s.
The author used a load of RVO-70 in that case.

The slowest powder I found usable in this cartridge is called RVO-70 by its distributor, River Valley Ordnance Works, in Harvester, Missouri. This extruded RVO-70 (also known as HC 30) was manufactured for 25mm ammo and is slightly slower burning than most lots of IMR-5010. A heavily compressed load of 87 grains of this powder under a 140-grain Nosler in the 264 Thor produces about 3265 fps, but extraction is sticky. RVO-70 is also good with the 155-grain Sierra match bullet.
