This weekend I had time to really spend the day shooting over a chrony. I set everything up, started at 250 bar & the 3rd. Setting in .25 cal. My goal was to get a reasonable amount of shoots while shooting JSB's Heavy at around 875 fps. Well, that was rather easly done. However, the problem was after this. I switched the setting to 2nd. power. To see where the FPS would be and it remained the same. So, thinking " well maybe there's just not much difference in just one setting. I kept going down to the minimum setting. Still the same result. So before I send it back to AOA. I wanted to know if I was doing anything wrong on my end. Finally, I loaded some just 25.4 grain just to see what would happen and it shoot them across the board on every setting 960's fps. For some reason I think my settings aren't working as the should. Has anyone had this type of issue? If so, what was the fix.... Now, I ordered some new Hi-cap magizines as well. None of them are working properly, they stick for the first 8 to 9 shots then start to turn properly....what's up with that. Do they need some grease or something? I'm looking forward to some help here. I'm a handy guy so whatever needs done I can do it. But I'm not arbitrary going to break the gun down with out some feed back from some much more knowledgable airgunners then I. Thanks SAS
