Have been to Northstar (indoor range in Makati Cinema Square- basement)twice this week. Both times developed itchy lung, coughing, black stains in handkerchief after blowing my nose (ecch, sorry!) Well, clearly those symptoms come from breathing the air inside that basement range. Must be some lead in there too. Do you guys experience these "symptoms" when you have sessions in indoor ranges? One shooter-friend of mine says it happens to him when he shoots at outdoor ranges too but I didn't experience "black nose hair" when shooting outdoors. This is really getting to me. Honestly next time I may have to use one of those disposable masks that medical personnel use. You guys who have been shooting for years in indoor ranges, have you noticed any ill effects?
