My thinking is that if head space is tight, it's plenty safe to shoot, but accuracy may not be as good as you like. But those that I've checked that were loose, had way too much head space, and puttiing a tighter forend on it isn't going to fix poor head space, it will increase head space if you think about what the tight forend does in relation to the standing breech, it's going to pull the barrel forward...... If I understand what you've said, Matt. :wink:
