Hi
Could you please let me know how could i find out exact timing between lifting charge and bursting charge typically for all size of shells?
I counted myself for a 3" shell and the time fuse burned for about 2.5 seconds.
I know this sensitivity may change with each manufacturer specifications but i need to know approximately timing of this delay.
I appriciate if anyone guide me for this matter.

As you have already worked out, the exact timings will vary...

Hopefully the table at the bottom of this page will help - it doesn't go up particularly far though.

Creepin_Pyro I would like to opportunity to thank you for your prompt reply with regards to your guide.
That table provides cylinder shell timing specifications but I havent ever use cylinder shell,i always use round shell in here.
Can i pretend these shells at same timing spesifications for round shell?
I look forward to hearing your thoughts and comments in the near future.
Yours faithfully

Edit- seems to be the same info given earlier.

Each shell maker will have their own idea of the correct timings for each size of shell. Also they will have their own manufacturing tolerance so for a good make +/- 2% and for an economy make +/- 5 - 10% of the chosen time.
