Sorry guys but I left out that info on purpose. Asking as a general question not any gun/caliber specific as I shoot several calibers, .223, 6.5, 7mm, .308. My local club range has me limited to a max of 300yds so what I'm getting at IS,... can a shooter be effective with loads developed at 100-300yds if they move on to a range that will go up to 1000yds. Some of the locals say it's best to develop loads for 100yds then 300yds then 600yds and then 1000yds. Seems like a lot of rounds to keep track of? A few around me shoot different weight bullets at different length ranges, like for the 308 they are shooting 155gr up to 300yds, 175gr to 700yds and 200/210gr to 1000yds. This seems excessively complicated as my thinking is just make one round shoot well all-around, maybe I'm wrong?
