I did OK, but nothing outstanding.
95 for 4th place with offhand target rifle - 50m
92 for 6th place with percussion target rifle - 100m prone
91 for 3rd place with BP breech loader (40-65 Rolling Block) - 100m prone
82 for 4th place with percussion military rifle (Enfield) - 100m prone
All prone shooting at 100m only a two-point sling is permitted for support (no cross sticks or wrist rests). Target is ISSF 50m free pistol target with 50mm (approx 2") 10 ring.
Re. matchlocks, the lock time seems to be at least on a par with and possibly faster than flintlocks; after all a lighted match is just being dropped into the priming powder!
