As a result of the test I made I now use Hodgdon extruded powders for all my rifle reloading. I no longer have to worry about change of zero or velocity change.
That is great if they shoot well in your rifle.I had avery accurateload for one of my rifles using the original h-1000,but the newh-1000 extreme producesover 100fps less velocity and group sizehastripled reguardless of the powder charge.I would gladly have the original h-1000 back.
