Interesting thread. Why do we have high brass and low brass? How do they differ?
I am pushing them around 1,500 ft for hogs, deer, and zombies. I just wasn't sure if it was a big deal or not.
The international Coalition for Undead and Necrotic Terminations reccomend only hiwall brass to be used on Zombies, it has something to do with ability of blood blowback and brain matter seeping in to exposed shells with low walls.
