I've got a great load worked up with 115 Bergers in my 8 twist 243AI but was thinking about putting together a little zippier load for it as well for closer shots and just something fast in general. My question is if I will have any problem shooting lighter bullets (75-90 grains) in an 8 twist? I'm looking at V-max's, ballistic tips and the Swift Scirrocos. I don't know if I need to worry about over spinning the bullets or anything like that before I start down this road. If you have any suggestions I would surely appreciate it.
