I don't know what kind of MV you would loose if you cut the barrel down to 24" I've went the Sendero route intially. Changed barrel to shilen, new HS precision stock, jewell trigger, bedded, trued/blueprinted. The only original piece is teh action. Talk about the long way around. HAHAHA but it was fun and an experience. If I had to do it over again I'd try a used action, HS precision stock, Kreiger or Broughton barrel, jewell trigger
The easiest is to get the Sendero. Mine last three shots from my barrel break in were .6MOA so don't ask why I started changeing things. I blame this site whole heartedly
If you do get the Sendero I would get it bedded immediately. I was less than impressed with the fit of the action in the stock.
