Seriously, will the California 10 round magazine limit on EBRs be recognized in the rules?
No specific magazine limit for rifles/pistol caliber carbine, just that a stage with 15 shots or more must involve a reload.
For shotguns you can only have 6 total shells in the gun and a stage is limited to 10 shotgun shots. Many people don't like that, I think it is reasonable and keeps the shotgun stages from being speed reload competitions like in IPSC.
