A couple more ideas;
No need for a target if you just want to see the splash. Pick a nice large flat area where you can see dirt being kicked up. If there's snow on the ground the bullet disappears, but if it is thin then it's perfect. Brown dirt splash on a white background. Sand dunes are perfect too, especially if they are steep and facing you, You use the previous splash as the aiming point for the next shot. Dried-up clay lakes etc. If you are a land owner you can level a clean spot to see the splash or even push up a bit of a berm which presents a slightly more vertical target.
Or, if you have the time you can make a poor-man's electronic target with three pieces of plastic Corflute signage and two pieces of metal (aluminium) fly screen. One piece of signage acts as the insulator and as the bullet passes through it completes the circuit. You can use it to turn off and on a flashing light which you will see through the scope at that distance during the day, or with the naked eye at night.
