I would recommend a freebore/leade/bore/groove/case mouth slug rather than a chamber cast.

It is the bit between the case mouth and the start of the rifling that is key not the chamber.
Read Texasmac's article on chamber casts and impact slugs in the library for how to. Impact impressions give far more accurate results than casts with cerrosafe and the like.

Ah yes my mistake I wrote chamber cast thats not what I meant I dont do the cerosafe thing.
I meant a impact cast I did one before on the AIA the results of that one was quite surprising. It enabled me to purchase a suitable mold from NOE that works well.
