I get the P* guys have their own issues, but here's my take:
Chrony at 350 with .20's.
Shoot with .20's at 350. Disallow higher weights and higher fps.
You don't need .28's or .30's for indoors. You need that outdoors for cutting through bush.
I understand that .28's and .30's fly straighter, but to what margin within 100 feet? All you're doing is increasing the pain threshold.
As for joule creep, take that into account when you tune your P* and GBBR. Shoot less hot. It's a courtesy. FPS limits are limits. Not goals.
The whole "but .20's don't feed in my gun" is bullshit. Buy better brand BB's.
EDIT: If you want to be a super gun doc and tune your guns to run within the margins of the rules, expect backlash when rules are changed or the chrony is acting up.
The other option is just to tell people that any FPS and any Joule is allowed, dress for the game, and chrony to ensure the gun isn't at firearm levels.
The lesson learned here is that whenever you establish rules, some fucking snowflake is going to want to bypass them to get "more performance", and you need some scientific method to maintain order across the board.
All of the issues discussed here is why I (and many others) don't attend public games. A lot of private games run without FPS or Joule limits, but we are all buddies and accept that we don't want to hurt each other. In public games there are often psychopaths who enjoy inflicting pain on strangers, and I've experienced it first hand at many locations across Ontario, and called them out on it for either running hot or doing some other dangerous method of play. I'm sick of it.
EDIT 2: If you're running flat hop/rhop etc, just buy a different barrel setup for indoors. Flat/RHop is designed for extreme range. If you're running a $1200-2500 gun, you can afford to stop bitching and buy a $200 barrel system for indoor play, or invest in a $400 complete upper and drop it in. If you can't, you shouldn't be running such top kit. /keyboardcommando
EDIT 3: Mach1, sorry for shitting in your thread
, the above has been bothering me for years.
I like what you guys are doing and I've got a bunch of teammates who love the new arena. Keep up the good work!
