I am trying to determine what a good starting load for the 40 grain v-max with RL-10x would be. I have Todd Kindler's book. He lists loads of 18.0, 18.6,19.2 and 19.7 grains in that combination. I think the general rule of thumb is to reduce loads by 10 %. So does that mean I should reduce the starting load of 18 grains to 16.2 or just start at 18 grains since 10% of 19.7 would be 17.7? I am just playing around on paper at the moment at 100 yards so velocity doesn't matter right now. 1-11 twist criterion barrel on a savage action. Thanks.
