Daryl,

I'm also using BLC-2 with great success in my 9x57R double rifle. It's barrels slug out at .358", so I'm using the 250 gr. Hornady round nose. Also CCI-250. My brass is formed from .444 Marlin. I don't remember the powder charge and don't have that info available now.

In a similar vein, I have a No. 3 Ruger originally chambered in .375 Win. that has been re-chambered to .444/.375 and it eats BLC-2 likewise.

That powder seems to work great in relatively large bores with moderate size cases. I would think it would be great in the .35 Whelen or the .358 Win. but I have never owned rifles in those calibers.

One great advantage: it meters like silk.
