As mentioned in earlier post, Midway and Hornady are not the only sources for brass. You did well picking the caliber you did, it is one of th best DG offerings out there. (subject to debate I'm sure) You would have to shoot a whole heck of a lot of 458 Win. to damage your chamber, somebody did a test (heck if I can recall who?) and they found that after 700+ rnds or so, no effects.. Yes, the sights are bulky and somewhat crude, but as mentioned they work and work well. Their biggest asset is they are very sturdy, and yes the stock is the weak link. Be sure to have it at least glass bedded and perhaps a crossbolt added.. AHR makes a fantastic trigger to replace the piece of crap set system (IMHO).. Other than that, enjoy and good shooting....
