The differences we see in velocity between these, reman and the Remington's all with Power Pistol is? Could it be seating depth, tension, or something else?
I really think it is the plated bullets, even though they are the Xtreme brand it may be shearing at the lower velocity in some barrels. The velocity should be a good bit higher.
Here is a more direct comparison of the power...
LAX is using this powder...

This is Power Pistol powder...

Both IMR SR4756 and Power Pistol track fairly close but Power Pistol seems to have a slightly higher velocity yield...
