I went for a 243 as my first rifle which i got with no problems except i had to gain experience by going out with someone who has owned a centre fire , it was written in the condition's part on my fac which i had taken off after a couple of month's. Both my rifles are CZ which i think are great value for money and very hard waring and most importantly they both hold there zero perfectly , your gun cabinet should be OK if it is police approved but you might have to buy a separate ammo box for about £50, as for cost firearms is £50 and co-terminous is £60.
