When using the drum or WSM and running it hot, it can be done within an hour or so. When using my Lil Chief, (much lower temp) it will go 3+. Bottom line is, my kids can't wait 3+ hours when I make jerky, hence, I go with higher temps. The other bottom line is that if you have kids, they will EAT ALL of it faster than you can make it if you used high temp! That I guarantee.:becky:
