It looks like you trapped air in the mould when the casting resin went in. Try adding just a bit first persuade it about with a cocktail stick and then the rest.

My first moulds were a bit like that too - but it's fun isn't it!

Aaaaah.......... hold fire a minute ( groans) shells were generally transported without the fuses in - they would be in their own crates.

This could be helpful to you, as the noses wouldn't be pointed but flat. You do need to be slightly careful though as various shells had different applications (other than the different calibres) and often had coloured bands painted on them as identifiers. Also there would be wood packing between them to stop their surface being damaged by rubbing against each other. Damaged shells would not fly true or may damage the bore of the gun barrel, even leading to misfire (nasty)

No squirrels were harmed during the provision of the shells......

Being under an MG is an honourable place to be in my book .......

As to the packing.. mayhap you're right - I wasn't there after all although I do have slight concerns as to how I know off an awful lot of this stuff......................................

Great job on the castings, well done.

What type of resin did you use and from where may I ask?
