Really trying to complicate things aren't you.
Likely a "potato vs potatoe" kind of difference between those barrels, but I've never heard of a bad HW barrel...cannot say the same of BSA barrels.
How the rest of the rifle is "set up" will alter "how" you chamber the barrel. Springers seat the pellet flush, and like a "tight" chamber and a little relief for the skirt. Many pcps have the pellet being inserted past a transfer port...some don't.
My chamber is .180" through to the leade, with a 60 degree leade into the rifling. I use a flow through probe, which seats the entire pellet past the leade and into the rifling. Where the pellets make entrance to the chamber, the edge is also deburred at 60 degrees.
Should go without saying, but the chamber and leade should only be cut after CAREFULLY centering the bore.
If you need to chamber the barrel, do that job first...then drill and deburr any transfer ports. If you do it the other way around, the missing material WILL pull the chamber reamer off center, and ruin the job.
Do a google for D style reamer, or ask one of the machinists. Easy to make and work very well with care.
This (LW) is only the second barrel I've chambered, but I'm pretty happy with the results.
From the bench @ 25m. These are ten shot groups fired after initial zero of the scope. JSB Exact heavy on the left, H&N Barracudas on the right. I simply cannot shoot any better than this, so time will tell if there's yet room for improvement.

Liberalism is a mental disorder, reality is it's cure.
also ready to use, so is it decently accurate? If it´s ok, I may change my mind about the HW barrel...
