Based on your experiences, can you tell me if adding something like a brake or suppressor will affect group dispersion or mostly just point of impact. I ask because I've spent time and money doing a decent load work up and dont want to do it all over if a brake will cause my existing load to blow up.
Thanks.

Most of the time POI is the only thing that will change.
