FX Panthera 500mm .30 help ??

Does anyone have pellets or slugs they can recommend ? Can someone recommend a good starting point with settings? I am hearing conflicting stories about slugs with the 500mm barrel, can the 500 mm barrel shoot slugs if it can what brand and grain do you recommend ? Just got this and didn't realize it was mainly the 600 mm and 700mm that shoots slugs any help would be a good thing for me thanks in advance.
 
I actually shoot a shorty 395mm .30 cal Pcat Hunter Compact. In any case, the standard liner shoots hybrid slugs perfectly, as well as NSA 47.2.

Run that 500mm gun at 160 bar, 13.2 gram (8mm head) hammer weight or the Huma 14.5g hammer weight, 3.75 on the micro tune. You'll shoot Hybrids around 960ish.

Here's the video on the Pcat hunter compact tune.
