I don't know how many of you fellows shoot at Friendship but I've been going since I was 12 or 13, I didn't go for a few years after school but started back up in the 80's. I shoot mostly offhand, and have shot, x-sticks, woodswalk, and a little bench, I also shot the novice trap a few times (still a novice!).
On the offhand line there are numerous matches for flint and percussion, flint may be used for any match, there are also matches for open sights and for AMS (any metallic sights) when I shoot an AMS match I shoot a rifle set up with Redfields, in the open sight matches I use opens, there are so many aggs that one would be hard pressed to shoot them all especially at the fall championship, I usually only shoot in 4 or 5 aggs and several individual matches.
I guess what I'm getting at is I won't break any rules at any shoot, if they only shoot opens then I'll use opens, if it says AMS, I'll use the Redfields. If I'm going to a place I've never been to before I make sure I have an open sighted gun with me.
I have set some records over the years and finally made it into the Master classification a couple of years ago, the records I own were shot with both open sights and AMS, I will shoot either type of sights and will follow the clubs rules.
