I'm new to the bullet, just bought my first at the beginning of the summer. I have made ribs 4-5 times with good results. I tried the championship injection recipe and followed it to the letter with one exception. No bone in butts were available so I used two 8 pound boneless. I followed the temp very carefully and at 18 hours I still only had an internal temp of 182. It never did get to 190 as the recipe indicated. Is this normal? Did I do something wrong? The meat tasted good but was a bit tough on the outside. I did not have time to cover in foil and put in a cooler. I had hungry poker players waiting!
