Changing choke

[William Davis]

When the gun was built Chokes came first, then regulation two most important steps. Ribs laid and outside of the barrels filed and finished. All hand work . 100 years later try to alter the chokes nothing concentric to set up tooling. Run a reamer in the barrels it may center or may not. It has to index on something to run true. Look at a lot of Parker’s in a large setting like the Southern you will see many open jobs that have gone wrong. Muzzles not concentric and who knows what it’s done to point of impact No doubt it has been done successfully but many botched jobs.

Modern shotgun machine made the barrels are round and straight, opening chokes reasonable thing to do. Vintage hand regulated gun it’s a mistake.
