I'm not clear what the list in the first post was meant to exclude, but I have owned a .22 target rifle so I guess I should tick that box anyway. I shot in rifle clubs and in my university team. I also shot on the university outdoor range with full bore (ie 0.303 and 7.62mm) rifles, and in the Navy with automatic weapons.
I have no problem with gun ownership with closely controlled licensing, usage and background checks. I am utterly against the "cowboy" attitude of the idiots in the American NRA, and find it incredible that this attitude is still allowed to prevail. I often argue against the NRA attiude on certain forums with a high USA membership : the attitude seems to be "If we ban/restrict guns then only criminals will have them". They have no concept of eg the British culture where it is very rare for criminals to use or be seen with guns, knowing that the police for 50 mile around will drop everything else and descend on them like a ton of bricks if they do, and that they will be dealt a far harsher sentence when it gets to court.
