I have no interest in shooting past 500 yds. My rifle range only goes that far and my hunting ground only goes out to 400 yds. My longest kill was 327 yds. So, since I've always reloaded my ammo, I have just dabbled in some of new bullets designed for shooting distances far past my needs. There are so many new bullets that go with faster twist rates, it drains my energy to try and stay familiar. I pretty well just use cup and core bullets, a few solids. Is there anything to be gained at my distances, using bullets touted as Long range, super efficient?
