Avenger bullpup.25

Hey guys I've been looking around here for a few weeks now. I have the avenger bullpup.25 and I have it set up the way I want and like with nsa 26.8g and nsa 33.5g slugs, now it's not my first pcp I also have a flash qe carbine. Both rifles are lasers but I was wondering if anyone else who is into pcps is in upstate south Carolina.
What kind of groups at 100yrds are you getting with those NSA slugs in the Avenger?
