Can it be MY mother in law you use for this in the future?
I don't want to sound patronising,but you always MUST drop your loads a few grains when changing ANY components in your handloads,if not your 'Dancing with the DEVIL'.
It is fundamental that you ALWAYS do this,guns aren't cheap,and your life is priceless!
Keep it SAFE!
