Blaser - don't do it.

And if you do, you better make sure that you're in love with it - if not, you'll never get your money back.

Merkel, Searcy, Chapuis, Heym... handle them all and pick the one you like best. They're all good guns, but the Blaser is IMO too far removed from "traditional" for serious double rifle buyer to consider.

Good luck.
