I saw this article posted on another site and thought I ought to carry it over.  It covers some interesting details on very very very very very precise bend rest shooting along with a story about an big storage warehouse that was used for shooting a while back.  I'll give points if someone can explain what some of those cartridges are that they are using. 



Here is where I picked up the article.  They have a fairly active buy/sell section which keeps me coming back.

6mm PPC- I think is based on 7.62x39 necked down, body blown out/straightened with the shoulder angle changed- I think. I've never seen one, but I do see a lot of 6mm BR and 6.5x47 at the local club in F-Class Open class rifles.

Cool article though.
