you have a great gun. my post is still up in the black power forum,read it and you should get some confidence but for now I will give you a quick fix. first of all I own 2 of these guns,I'm not saying that I'm an expert but I will tell you what is working for me and maybe it will help you. My loads are 2 triple seven pellets and the TC 250gr shockwaves. they are tough to load but I would rather have tight then sloppy.I then changed the sabots and now I use the harvester green sabots with the shockwaves. a little eaiser to load but still snug but the accurcey is incredable. the other gun uses the same power charge but with the harvester 240gr. hollow points. I can touch holes with a 3/4 in grouping 1in. high at 100 yards. the only thing that I might change is I'm going to try BM2 power because of the crud ring problem with triple 7. good luck!!!!
