Well Cullenz list was pretty crazy as it is all based on the idea that shooters only shoot semi auto firearms and not any other. And of course wouldn't transition to allowed firearms in those calibers.
By wiki https://en.wikipedia.org/wiki/Arms_(Prohibited_Firearms,_Magazines,_and_Parts)_Amendment_Act
There do not seem to be any caliber restrictions in this at all, so if you get a bolt action rifle in 5.56mm Nato with a magazie of 5 rounds you can use all the rounds you had for your ar-15.
That list is based on the weird idea that shooters are only interested in shooting semi auto and so their shooting kit is useless with out it. This assumption is really weird. Cullenz should read up on the new law and see it does not seem to outlaw any ammunition in any fashion.
I never said it did
I just badly worded the point that if someones guns have to be handed in they are left with shedloads of pointless ammo' the govt aren't giving cash for
