2000 rounds of 22LR would be 15 pounds in just ammo and over 20 pounds with the rifle included. If you're on the move permanently without supply caches, you'll need extra "other" type of gear to carry. That's a lot of weight.
Even 2000 bullets would eventually run out. You pretty much have to plan on resupply at some point. Save yourself 7.5 pounds by stashing a brick so you know you can come back to it later, rather than carry the extra brick on foot for a year.
In army basic training, I did a 15 mile road march with 60 pounds. That's really not very far and I was wiped out.
