Well I'm about ready to go to the range. I have some Pyrodex RS loose, some 777 loose, Some 777 50/50 pellets. Some T/C Superglide 270gr SW's, some lighter SW's, Some 280gr. Powerbelts, and some XTP 300gr Mags w/crushed rib sabots. Now..... I'll see what this new Z5 will like!! I also bought a new scope. Rangefinder for the CB & ML. and a shooting/cleaning vise. Even have 20lbs of shot in an old bank bag for weight. I should be getting close...

Those XTP Mags should knock a buck on his a$$!!! I hope they group well. Hopefully the Powerbelts shoot close to the XTP's if not I'll be putting them on EBAY! Powerbelts are kinda expensive bullets.

You cannot shoot the PowerBelts too fast, only 1400 fps, be careful of that with your loose 777. I shot the factory recommended loads in my gun to begin with, just to make sure of grouping.Sounds like your into it to find a good bullet and load for your new rifle. Best wishes on doing that.
