I believe the lowest pressure 12 gauge load RST offers is their 2 1/2 "Falcon Ultra Lite" 3/4 oz. shell at around 4500 psi. Their 2" load is listed at the same velocity of 1125 fps but uses a heavier 7/8 oz of shot. Alex, Jill and Morris are always great people to deal with and would definitely be worth calling at RST for more information. I hope they are able to get a shipment of powder and get back on line loading again soon. HTH.

Fred, what evidence or experience do you have to suggest a shorter length hull will produce more pressure than a longer hull with the same primer, amount of powder, wad and shot weight? What would cause the pressure to increase when each is fired in a gun with the proper chamber size or longer chamber size? I don't see the physics that would cause that to happen.
