I'm making some 308 this morning and have a question about the correlation between the effect of different case capacities on an accurate load. For instance:
Known accurate load using Fed 7.62 headstamp case with a H2O capacity of 54.9g vs a LC 14 headstamp with a 54.0g capacity, or 1.6% less volume.
Is the 1.6% difference linear and should I reduce my charge from 39.7g to 39.0 to achieve the same performance, or are there just too many other variables that make this one not relevant?
