I’ve built a permanent brass catcher out of t post and green house shade cloth, it’s pourus enough that the wind doesn’t affect it so much. And i think made of some kind of poly marl. That last forever, I’ve had it for at least 20 years. Doesn’t melt with hot brass. Very tough, i think it came from Lowes, garden dept. 6’ X 40’ good stuff if your going to get for long time.
