So I have been using the SmokTech DCC tank and the pre punched cartos for a few weeks now and decided to start punching my own. The problem is that it doesn't seem to be feeding the carto properly after I punch them. I punched a substantially larger hole compared to the pre drilled ones and I am not noticing any air bubbles escaping from the hole unless I take a very large (and unusual for me) draw, and not even everytime I do it. The bubbles are also very large from this. Did I make the hole too big/small? Would adding more holes help if too small? Maybe the indentation from the punch is effecting the airflow?
I only have a few more cartos on hand right now to punch so any input on how I might better punch these is much appreciated!
Not sure how visible this is but here is a picture of the size.
