By the way, I chose to use Federal Gold Medal paper hulls, Federal wads and Federal primers. Not all that common and not the most data available in the lower end of pressures. If the "Gucci-ness" of paper hulls is not important to you, I'd recommend the Remington STS hull as opposed to the Winchester hulls. There has been a lot of controversy over the new Winchester hulls with the separate basewad that has been reported to come loose and cause an obstruction. I don't know if any of it is true or the causes if it is true. I just avoid the problem by using other components. I believe the STS hull is as good or better and they appear to have an integral basewad. And, STS hulls are fairly common at ranges.

Just my two cents.
