Cutaways not really my thing but look good for 1st attempt.
I like the Hispano & should look good after a clean up, pity there`s none of the fuze internals.
The .303 I would have completely halved the bullet then soldered or super glued it into the case. Also I cannot see the flash hole from the primer to main charge?
Good effort all the same & as they say practise makes perfect.
If you want any other small arms rounds to do PM me as we can sort something. I also have some poor conditionWWII German 20mm projectiles that may benefit from this?
