I have a new to me 243 target rifle that has a 1-10" twist, so the longest target bullets per the makers are 90 grains. I see Berger and Lapua offers such bullets and I am wondering if anyone has experience with either. I'm guessing that to ask if one is better than the other is asking if a Ford is better than a Chevrolet, so I won't ask- however, relating any experience you have with either one, or if there are other bullets that I should consider, that information is welcome. The intended use is target from 300 to 600 yards. I'd like to go further, but to do so I'd really need a faster twist and 15 more grains of bullet.
