http://dreadnought-adventures.webnode.com/players-info/Dreadnought Adventures recommends using biodegradable bb's and supports safe and reasonable weight/FPS limits - for outdoors game this is as follows ...
(chronographing requires each player produce an empty mag for the referee who will provide standard .20g ammo)
1) most pistols will have the bare minimum 10 foot safety distance - but gas powered pistols or any pistol using heavier than .20g will have a 20 foot safety-distance
2) guns 350 FPS and under with .20g at chrono (i.e. most stock models) will have a safety-distance [minimum engagement distance] of 20 feet.
3) upgraded guns/assault rifles shooting a max 420 FPS with .20g at the chrono,
playing with .30g pellets at the heaviest, safety-distance of 30 feet.
4) sniper rifles (no automatic fire please) up to 550 FPS with .20g at the chrono,
or any weapon playing with pellets over .30g (to .40g at the most)
safety-distance of 60 feet
(so bring a sidearm and use it for CQB).
5) grenade-launchers loaded with .12g have a safety-distance 20 feet,
and with .20g need 30 feet minimum - we recommend using foam 'rockets' which we count as having a 15 foot lethal radius where they hit the ground.
6) cap-guns may be used at 10 feet or less; with a clear line-of-sight, two successful 'detonations' in rapid succession are required to score a hit (and that counts as "vitals").
7) NERF swords, etc. approved by the referees, may be used with caution, do not strike at a players head or neck. NERFs may hit "limb" or "vitals". (please no Rubber Knives, nothing too realistic)
