A very similar .303 Gallery Practice was discussed back in 2007 when the unusual headstamp ‘8’ was shown.
This example is, I believe, a .303 Mk I Gallery Practice, Gaudet, with a deep neck cannelure to seat the bullet.
The second example is a .303 Gallery Practice using a Kynoch S.L case. Any thought on this would be appreciated.
The .303 Mk I Gallery Practice belongs to a friend, who was interested to know, if this cartridge was rare.
I’d be for grateful for any additional background on these two Gallery Practice rounds.
