Horses for courses. The semi for wildfowl and it can take 3.5 cartridges if I get extravagant. There's the Beretta Silver Pigeon for game birds. My most used gun and ultra reliable (fingers crossed). I've also got a Sabatti O/U that is really a spare if the Beretta ever fails and as a loan gun if needed. Which leaves the Gunmark Kestrel SXS (a sidelock, but a cheap one) for light days where more walking and less shooting is the order of the day. Although I must admit the SXS is the only double trigger amongst them and it regularly catches me out. Must use it more.
Not sure about pump actions. They have all but been superseded by semis now. I do like an Aya Yeoman (SXS) that I had and now resides in my son's cabinet. I've had a go with the odd Beretta SXS and thought they merge form and function excellently. I've no real desire to get into really expensive modern shotguns. I expect my bargain basement Beretta will shoot as well as a top of the range job. But never having tried one, a fine English SXS would be on the shopping list if the lottery were to fall into my lap. Just because.
As for rifle actions, most rifle shooting I do will only ever require one follow-up shot so the bog standard bolt action is what is simplest and best for my needs. I can see the need for a semi-auto .22 for hordes of vermin and also those who want the safety (real or imagined) of a double rifle for shooting anything that might become annoyed with you. Falling block actions are quaint but historical really and we are forbidden other semi rifles, but they are just the thing for that follow up shot and I have to say that any fully automatic rifle only should be used on the battlefield or at ranges (in my view but also, of course not allowed).
Black powder long arms can be fun, as can pistols. I've always had a hankering to have a go with the likes of a cap and ball Colt Navy or Army (other makes are available) revolver, but I also think I'd get bored with that sooner rather than later, just banging away at paper. I get the feeling it would be like owning a Harley. You'd spend more time cleaning it than using it.
Anyway, enough of my drivel. Off to bed for me.
