Either is a fine cartridge.
Pick one in a rifle that fits you well, in a platform you like and shoot it.
As for 500 yard shots, anyone can buy a rangefinder and a ballistics program and think they have it figured. Shoot at paper at distance and you will soon find out that doping the wind is likely the most important consideration, and one that makes hunting at distance best left to the folks neurotic enough to figure it out. Otherwise you may end up with gutshot game or worse yet that pit in your stomach when you cant find what you just crippled.
Only my opinion for what it is worth.
