I have 3 Savinelli 673's which are essentially bent to the same angle that the 999 is yet the hole is drilled in the center of the mortise. Some pipes are different than other pipes I'm wagering. But again, the hostility is super helpful and much appreciated.
Some bent pipes are drilled with the draft hole appearing centered at the front of the mortise. There is often a circular cut at the back of the mortise drilling where the drill removes material because the upward angle of the bit.
I would have to say that in my experience many bent pipes I have seen are drilled similarly to what you have with the 999, the draft hole being at the 12 o’clock position or into the mortise wall. This really has little detriment to the smokeability in my experience.
I have approximately 60 Peterson’s; It’s a brand that I have appreciated for over 30 years. Like any brand, there are quirks that are specific to the brand.
If the drilling is an issue that concerns you, then I guess sending it back is probably the only option that can resolve it.
As for the obnoxious comments, that seems to be the way that this board is going lately. I wouldn’t let it get to you. As the old saying goes, opinions are like assholes, everybody’s got one... ?
