What’s the deal re: ported and non-ported chokes?
I’ve covered this here:
My personal experience is that porting on shotguns does nothing meaningful for anyone except the guy who is getting paid to drill holes in a perfectly good barrel.
There are three other things I also should have mentioned about ported barrels:
1) They can be obnoxiously noisy. Browning porting is particularly bad in this area. Some other porting is OK.
2) Ports can affect the resale value of your gun. Many people just hate them and won’t own a ported gun. Others don’t care.
3) Some owners of ported guns have complained to me about the extra barrel cleaning that porting makes necessary.
