Based on what you told me you have ~150mg/ml, 2%ba, 14%bb
I truely think that adding another 16mL BB is the best way to go for 2 reasons.
First off did you hear me when I said this shit hurts. 150mg/ml WILL teach ur hiney a long lasting lesson. Do your butt a favor and make it 100mg/ml at most.
I am however intrigued by your stubborness to add this bb. If it holds for a day or two, shoot it for a pain test and let me know what you think.
