Wow, thanks for the feed back. Looks like I won't be using these in the old girl.

Does anyone have a clue how RST makes them so low pressure? Types of powder and wads, etc? I have yet to cut one open to "explore" but think I will tonight.

Andy, low pressure is different to different people. A lot of us reload around 5000 to 7500 psi. Some consider anything below 8 or 8500 psi to be low pressure. For years it was the 7's range for me, now it's anything in the 8's or lower.

Andy, I once called RST and ask what wad they used in their 10ga shells. Remington SP-10 I was told. I said they seem to be a loose fit in any 10ga shell. He replied " how do you think we get low pressures ? " I once ran out of my 3/4oz 12ga reloads and had some 1oz RST shells handy. They shot every bit as soft as my reloads.

Thanks Paul. I cut apart an RST Falcon Lite the other day (16g) and it was surely a Gualandi Sporting 16 wad. The powder looked an awful lot like International Clays to me.
