What common calibres are in the UK?

[Phil]

Common calibres I would consider are 9mm,.38 sp/.357 mag, .44 sp/.44 mag,.45acp,you can find all these in carbine or rifle and are easy to reload with the right equipment.
Rifle calibres .223,7.62,.243,.270,.303, 30-06,and .22lr.
If you only have one rifle in each of the bottle necked calibres,then you only need to neck size the case as it is fire formed to the chamber.
If more than one rifle,you might find that you are very lucky and they will all accept the neck sized cases,but its very unlikely,so you'll need to separate each rifles cases.
