Hello everyone!
Hope ive posted this in the right section! Ive encounterd a rather strange problem that id like some advice on. Up until recently ive been building some spectacular and sucessful shells with hand rolled stars. So i decided to go a step further and make a star roller. Which i did and wanted to roll some nice silver to purple stars using a silver tail comp that id sucessfuly used before. When i fired the shell all the stars apart from about 4 were blown blind. The strange thing was is that i was using a star comp that had worked perfectly before but on this occasion failed! So finaly my question to you guys is..........Are machine rolled stars denser and harder to light then hand rolled stars. By the way burst charge and priming methods were exactly the same as the sucessful shell id made previously with hand rolled stars. CHEERS!

It may be the opposite of what you're thinking although highly unlikely: your rolled stars are softer then the hand rolled ones so they get crushed by the burst.

If I were you I'd increase the priming layer, make it hotter, and I'd go for a stronger pasting to fix the issue.

Ok thanks for your help i will give that a go. By the way the primer i was using was a bp/silicon mix. So i think il step prime these stars using 50/50 bp and star mix then do a final coat of bp/silicon prime!!
