I've been shooting F-open just under 12 months now at my local club. Also been checking out a few web sites to get a few ideas. One thing I came across was talk about what your rifle sits on when using a rest. Carpet, sandbags etc. My rifle has a 3" plate(Davies) and sits in a plastic block that is a fraction wider. Is this setup legal?

The other question I have is about clearing my rifle when leaving the mound. It is a MAK tubegun(.260) and to remove the bolt I have to undo two small screws with a allen key and slid the butt stock off to remove the bolt. A slow and painful process on the line. My club is happy for me to use a chamber flag. I get the RO,scorer or checker's attention show them the flag going in and get the thumbs up to leave. Other members are happy with this as well.
What is the go with using a chamber flags if I was to go interstate for a shoot. It lessons the chance of me loosing those smalls screws in the grass or at worst a bolt. In Aust these type of stock setups(MAK,Eliseo) are becoming a bit more popular. I know in the US chamber flags are mandatory on most rangers.

Would like some comments please.
Thanks
