[QUOTE="Mikecr, post: 155562, member: 1521"] There is also BC-vs-Velocity to consider depending on your cartridge and use. This, putting aside accuracy, recoil, barrel life, energy, etc. If you could choose for instance 243AI [email="55gr@3850fps"]55gr@3850fps[/email] -vs- [email="105gr@3000fps"]105gr@3000fps[/email], and you only intend to kill varmints out to ~300yds, the faster 55gr might be flatter and straighter for you. Just opposite for 600yds.. Play around alittle with ballistic software & see. [/QUOTE]
