Everything I've read indicates that a heavier bullet will require a lighter charge than the exact same bullet of a lighter weight. However, Ranier plated RN 115gr bullets range from 4.9 to 5.9 of AA#5 (1.14 OAL) and the same bullet in 124gr ranges from 5.6 to 6.4 (1.16 OAL). Does the difference in OAL make that much of a difference in charge?
