How are you folks holding your firearm for testing accuracy?
I suggest that you use a rest. It is the only way to tell the accuracy of the load. After you determine accuracy from that, then you can go on to your defensive stance and see how well you shoot each load.
At 10' I should be able to make them all touch from a 1 7/8" barrel using that method. If not, I would scrap that load.
