NM/HNO3 det probs
Hi i am having problems detonating a 70:30 NM/ 70%c HNO3 solution. I have used a cap with about 1-2g HMTD with 100mL charge and im not getting a
detonation. Should i use more primary? Is this HE even worth messing with, btw im using 99.9% pure NM and completely clear 70%HNO3. should i be
putting these chems to better use? would using cloth or sawdust or some sort of absorbant help with the inconvience of using a liquid HE and not
affect VOD and brisance? First post, been reading for quite a while and experimenting on my own but this is my first venture into liquid explosives.
Would somebody explain the best way of putting the cap in the charge, i just use 1 1/2 in bic pen tubes sealed with hot glue and a safety fuse. Thanks
for your help and vast knowledge!

I've made several NM/HNO3 charges. For small charges (about 250ml or less) I used a ratio of 70/30 (100%NM/70%HNO3), and for larger charges I used
75/25.
I mixed the two on site to ensure detonation as they wouldn't always work if I'd let em sit for a while. The caps I used were about .5g PETN with a
little AP.
I liked NM/HNO3 charges as they were easy to scale up. But NM is just too damn expensive now!
