Might want to give Greg Tennel a call at Gre-Tan rifles . He Konws a great deal about rifles , machining , gunsmithing and accuracy ! He's also a real nice guy to talk to .
Here's a link to his site :

Even if you don't choose to have him do the work for you , you can get some good information from him . This man DOES know what he's talking about .
And , out of the calibers you mentioned . I feel that your best bet at getting a one hole rifle would be a tight necked 6BR .
