I've just had a call from the reloader and he informed me that he contacted Hogdgon to query the load data he had for the H110 powder he was using, he was stunned by the reply, he was told that H110 should not be used for reduced loads and they do not hold any responsibility for anyone not adhering to their data, this is why reduced load data is not produced by Hogdgon for this powder.
I rest my case.
