Was just wondering if anyone has any experience with casting for this caliber. I'm trying to reach about 2000 fps. I have heard of people using IMR 3031 and H4350. I also have 748, Varget, and AA2400. Any idea of charge weight for any of these powders for 185 gr cast boolit.

I found some heavy target barrels for Mosin Nagant. What are these from or are they aftermarket? I was thinking of a mosin chop cut rebuild project this year and if these barrels are a nice upgrade then I think I will get me one. http://www.tnguns.com/shop/index.php?main_page=product_info&cPath=...
