I vote for a 375 H&H in a CZ 550 with kevlar stock. They are a bit heavy which I like in this caliber and hold one extra round over others. In terms of finish, no CZ doesn't have stainless models but with your mentioned budget you would have more than enough to purchase the rifle and send it off to get a fantanstic finish much better than stainless steel IMHO. Also, CZ rifles plain work and like a wide variety of reloading recipes and in my experience are not at all finicky. Good luck and have fun with it.
