can i get an old A5 with screw in chokes?
Yes, but it depends on your definition of "old"
Browning started offering A5s with choke tubes in the mid 80s. First with Invector tubes and then for a few years in the late 90s with Invector+ tubes. These barrels are steel/hevi-shot safe.
Fixed choke Japanese A5s are steel shot approved, provided their choke is no tighter then Modified. If you have a fixed choke Japanese barrel you can have Briley install either Invector, Invector+, or Briley thin walled choke tubes in the barrel. I had this done on a Japanese Buck Special slug barrel so that I could use it for turkey hunting. With this system you can still shoot stee/hevi-shot.
On the older (<~1976) Belgian made barrels, Browning recommends that steel shot not be used in any barrel for two reasons. The first is that Belgian barrels are thinner then the Japanese barrels are know to form a bulge at the end of the barrel after shooting steel shot, particularly through a tight choke. This bulge is purely a cosmetic problem (unless of course is screws up the rib). However, some people run steel shot through Belgian barrels for years without a problem. The second reason is that the Belgian barrels are softer then Japanese barrels so steel shot will scour the barrel over time.
Briley can install their thin wall choke tubes on Browning Belgian barrels but the barrel still won’t be steel/hevi shot approved. I would recommend against this because it will change the handling characteristics of the gun. The advantage the Belgian guns have over the newer Japanese guns is their handling. Their thinner barrels/forearms balance better. Adding chokes tubes to the end of the barrel will change the balance of the gun.
If you have a Belgian A5 and you want a different choke for either a different pattern or because you need to shoot nontox you have a couple options:
1) Buy a Japanese Invector/Invector+ barrel. Assuming your A5 is made after about 1935 you can put the Japanese barrel on a Belgian gun without any problems. You will probably have to do some sanding on the forearm to prevent rubbing. These barrels are expensive. Midwest gunworks sells “new” Browning A5 Invector + barrels for ~$450.
2) Have Briley install their thin walled choke tube system. As noted above this changes the balance of the gun and still doesn’t let you shoot steel shot.
3) Buy a fixed choke barrel of the construction you want. Depending upon the manufacture you may/may not be able to use nontox.
4) If you’re wanting to shoot nontox through a Belgian barrel pick up some Hevi-Shot classic doubles or Bismuth shells. They’re by no definition cheap but they’re probably less expensive then the other options above.
