MSSA is a great facility with alot of nice people.
What is the average number of rounds that you fire at a steel challenge match?
Minimum round count is about 150. It's steel so I'd say bring 200 in case of any reshoots or like me, I miss
an awful lot!! Usually 6 stages of 5 strings. 5 rounds per string. You can shoot centerfire or rimfire or both.
