Although I prolly have less than 500 BP loads out the tubes...I have never had a card or fiber filler smoking on the grass or marsh. Recovered card wads show no sign of torching....fiber fillers dissapear in a confetti shower and natural felts under the shot show shot dimples but no charring?

Would be more worried about coarser powders in lighter loads showering embers, no?

Best,
Mark
