Reading through the CA big game regs, I see there is a .40 min caliber for hunting big game. However, there are several online resources that also list a minimum projectile weight of 170 grains for our state. The grain weight requirement, of course, would prohibit the use of roundball for anything smaller than .54 cal since we can't use lead. Not finding anything about this in the DFW reg books makes me think this may have been a requirement in place before the lead ban & is now obsolete info. But I'm curious if anybody knows the story on this. Is it just online BS? Is it obsolete info? Or is it actually buried somewhere in the regs & in-place?
