Why did you set a 9000 PSI pressure limit on the load?
If you're shooting a very old gun that may have seen more than its share of over-pressure loads, I understand completely,
If you're looking for a low-recoil load and think that "lower pressure" = "lower recoil", you're barking up the wrong tree.
Chamber pressure is not what determines felt recoil. Felt recoil is a function of how much weight you're trying to move and how fast you're trying to move it. That is, all 1 oz. loads moving at a true 1150 FPS will give the same felt recoil regardless of the chamber pressure they produce. Same with 7/8 oz and same with 1 1/8 oz.
I like to keep my pressures above 9500 PSI with 1 oz. loads for consistent burns. Light loads generally produce lower pressures than heavier ones; depending on your powder, if you start with only moderate pressure you run the risk of getting erratic (incomplete) powder combustion and that makes the performance of the shot load inconsistent as well.

9000 PSI was stated cause I've always been told you want to keep your load between 9,000 and 10,000 PSI. ( I don't know any better) I've only been shooting trap for three years and I've been reloading the same amount of time. But I've recieved my infomation from a couple guys who have been reloading/shooting for several years. I figured they've been at longer than myself so they "must be right". Thanks for all the comments, I'm proud to be a member of this site, I find it extremely informative. Thanks for all your help.
