Why limit yourself to 500 yards? I mean nobody but a fool would shot at an Elk or Moose at 500 yards with a production magnum round. But if you do not respect the game this might be your alley. http://members.aol.com/fiftyguy/ptrd20mm.htm
That's your opinion, and it's worth just what I payed for it. NOTHING.
Why is it every time someone asks a question you get a bunch of stupid responces.
Most of these comes from the ones that just want to respond and don't have enough scense to make a halfway decent responce.
I believe that you can respect the game you are hunting and still take one at or up to 500yrds.
As for the gun. I used my Rem. Sendero 300RUM last month to take two elk. Both over 400 yrds, and both fell where the stood. The load is 200gr. Accubonds over 92gr RL25. Zeroed at 300yrds and holds 1 1/4'' groups at this distance. At 400 it's 8'' low and 16'' low at 500.
It's also still packing close to 2600ft/lbs at 500 yrds.
To say that you are not much of a hunter if you can't get closer than 500 yards to your game is not correct either. Where we were at in Co., the range was wide open and on a 7 day hunt 500 yrds may be all you get.
Having said this ,there are some irrespossible hunters that shoot outside their capabillities. I know what my gun is doing out to 500 because I practice at these distances and if one does his homework 500 is very resonable with the right equipment.
