To the OP, if it makes you feel better I am also only a novice LR shooter. I find I can make very consistent hits to about 850y even with only a 9x cheap scope and a .223 RAR.

When I go to 1000, my inexperience and mediocre gear is shown up in a hurry! Hits are much harder to come by.

Shooting at 1000+ is hard! A lot harder than some people on the internet make out, or than some of the more skilled shooters make it look.
