To expand on the difference between hunting scopes and target scopes. With a hunting scope, you are typically going to need to put the bullet into a roughly dinner-plate-sized area to kill a deer or elk. For most of us, we are talking 200 yards or less. You sight in your Leupold (or whatever brand you like) scope on your modern bolt-action rifle and you probably have a ~2 minute of angle rig - maning that the point of aim will wander 2 inches at 100 yards. That still gives us -- (I am just guessing here, but that's really the point) -- what? 6 MOA to stay inside the dinner plate size with wind and distance estimations.
So....Hunting scopes are designed so that you sight them in once and stick with it regardless of windage and elevation.
Target sights and scopes are designed to adjust for windage and elevation on the fly. You are trying to hit a very small X-ring to beat other shooters. You also usually get "sighters" to see where you are hitting before you shoot for record.
I suggest you get a target scope and use it for hunting. Competitive shooting will get you a LOT more trigger time than hunting - which is a GOOD thing.
Check out the F-Class in high-power shooting. It's basically unlimited and allows for a nice scope and a bipod rest.
IMHO, $900 should buy you a VERY nice rig. Rem/Win/Ruger/Savage are great. ALso be sure to check out the CZ Varmint in .308. Claw extractor, set trigger, integrated scope mounts.
If you are leaning more toward competitive shooting, check out a Garand, AR15 or M1A for Service rifle. The Ar15 can't be used very well for hunting, but it's a blast to shoot...and you can just buy a $300 open sight 30-06 or 30-30 for hunting deer and elk.
As always...my bottom line recommendation is to get an M1 Garand while you still can.
