Some parts of the country really only have a competition season between April and end of September. Winter thaw until hunting season. So having regular matches in that window and the finale following in November for the serious competitors makes sense to me. There is already so much competition overlap from the end of May through August. PRS, NRL Hunter, ELR, Rimfire series, Outlaw matches. Just saying it’s kind of nice to have the PRS finale at the end of the event season and fall/summer season.
Rimfire league I shoot in has the finale in June. Monthly matches from July-May. But due to location and venues that close through the winter, it’s more like July-November matches and then April-May, then finale. Harder to get your scores, and travel to venues, and deal with weather.
