how effective is barrel bending for changing poi?

[mete]

Barrel bending is an old practice. In production barrels were checked for bore straightness and were straightened if necessary. Cold bending might cause changes in POI when the barrel heats and cools so it's better to have a properly made straight barrel. If you are thinking of bending the barrel just to change POI, forget it , change the sights instead.

Bend it like Beckam.

I had the barrel on the 870 TB bent to correct the low/left POI. It workd for a while, then gradually went back as the loads impacted the steel and let it revert.

Not recommended...

EVERY single barrel made is straightened (read BENT ) at some point in the production. This goes for all barrels, rifle and shotgun. They are ALL bent straight as a final operation before finishing, and then only so that the finish is not damaged otherwise it would be the last operation before it shipped.

Bending a shotgun barrel to adjust point of impact AFTER the final fitting of the shotgun to the shooter is perfectly normal, acceptable and even recommended!! Just make sure it fits before bending the barrel/s.

If your barrel will not hold a bend have it cryo treated and then bend it again. It will be nearly certain to hold the bend then. VERY few barrels will not hold a bend as they came from the factory and the barrel that changes POI with heat did it before the bending was done, bending will not change the heat related bending of a barrel.
