The Indoor Series is a series of three matches. You must shoot two or more to be eligible for prizes and the random pistol drawing. It is totally different from outdoor matches. Even the scoring is different. You shoot under a time allowance per string. It is a 50 round match. Perfect score is a 500 with 50 X's. The only thing the same is the D-1 targets, only they are heavy paper instead of cardboard. Prizes consist of Plaques, shirts, hats, knives. Average attendance is about 35 per match.
The Indoor Series is sanctioned by GSSF but run entirely by the host range.
