Did you end up getting H110 to work in your 300 blackout pistol? I have a 8.5" barrel im looking to start a load for. I have 150gr cast/coated bullets. I have read on the 300 blackout forums that H110 is better for lighter bullets but was hoping it would work out for 150gr as I have some powder. Modern reloading has some load data for it.. but was wondering if you had success with yours.
