Sir Henry,
The Browning A-5 20 gauge is an excellent choice for your needs, especially given your preference for a lightweight, versatile, and reliable shotgun. Its semi-automatic action reduces felt recoil, making it more comfortable to shoot, especially as you age. The 20 gauge offers enough power for dove, quail, and turkey hunting while being significantly lighter than your Remington 870 12 gauge, which can reduce fatigue during long hunts.
Considering your age and desire for a lighter firearm, the A-5's balance, reduced weight, and ease of handling align well with your goals. The classic design and proven reliability of Browning's A-5 make it a popular choice among hunters seeking a lightweight, all-around shotgun.

Hope the above info helps Sir Henry and Hopefully you'll catch some good Labor Day sales! Please take care and stay safe 🙏

the browning will be great however you may also want to look at the beretta a 300 with kick off recoil reduction (I have one and it has been great) budsgunshop.com/product_info.php/products_id/138990/beretta+a300+ultima+ko+20ga+28+black+shotgun

Your switch over makes perfect sense!

Hi Henry and welcome. The Browning A-5 would fill the bill quite nicely. A semi-Auto would work no issue. A known trick to cycle even the lightest loads reliably is to store a semi-auto with the bolt locked back to season the spring to fully compress as the initial stiff recoil spring is the bane of many light loads until a rigorous break in period. This will shorten that break-in drastically. Cheers, stay safe and enjoy!

Good evening to you!! The Browning A-5 is an excellent tool of choice. Just remember that with a semi- automatic shotgun they can be finicky. Shoot it a lot to find what feeds it well for the quarry you hunt. Hope this helps. Have a good rest of your day.

As we get older, I'm getting there too, we must sometimes change out our tools. I think what you've switched over to makes perfect sense in my opinion!
