You will.
Understand that every deficiency in terms of barrel accuracy, load consistency and scope repeatability will be greatly amplified at 1000. Add to that the ability to read conditions and compensate for them.
In other words, if you can get a 1" group at 100 meters, under perfect (and I mean PERFECT) conditions, you would be looking at a group close to 11 inches in size. In reality, it will likely be much bigger.
Milking big performance from small cartridges is terrific fun, I love it. I would just say that becoming an accomplished shooter at 100, 200 and 300M is no easy task, but it pays hugely when you do want to stretch out.
Component wise, match bullets with high ballistic coefficients are the key to bucking wind.
