The data sheet that comes with CB-0175 wads shows 16 loads with the Remington hull using 700X. All of them are between 7000psi and 10,600. Using a Cheddite primer and 14.4grs you get 1150fps at 7900psi. The Win primer and 13.7grs gets 1150fps and 7200psi [ the Ched with 13.7 would probably be the same seeing how they're both mild primers ]. I'm not sure how much powder you're using or what hull to get those pressures. You'll know if it's a clean burn by looking down the barrel after shooting. Do you see a lot of unburnt powder ? The only powder I've ever had problems with is 4756. That was at zero temps and 7/8oz loads - something that powder was never intended for. It was a slower burning powder meant for heavy hunting loads. You're not going to hurt your gun with loads under 8000psi. I shoot mine three times a week and never give it a second thought. As far as tight patterns - every gun can react differently to the same loads. The light loads pattern a bit tighter because the shot column is shorter resulting in less deformation of the shot in the bottom of the column when the shell is first ignited. More BB's stay round, the more stay in the pattern. When I first started shooting the clay games after a 30 year lay off, I went back to the 12ga 1 1/8oz load like I always had shot. Got reading some clays magazines and went to 1oz, then 7/8oz, and finally 3/4oz. Every step I'd be looking at how much shot I was loosing, but ya know, it didn't make a difference in how or how many birds were broken. And, it was a lot easier on my wallet and shoulder.
