I have never used this powder, but am curious if it works well with cast lead bullets, given its name. Any experience with it in 9mm or 38 spl.?
With a name like "PB", is this powder good for cast boolits?

PB stands for Porous Base. Yes it's great for cast bullets, in rifles as well as in handguns.
In .38 Special 4.5 grs. with 158-grain SWC approximates standard pressure, not +P.
In cowboy rifles 5.0 grs. will give about 1050 f.p.s. with 158 lead. Do not exceed this in guns not rated for +P ammunition.
To approximate +P with 158 lead use 5.5 grs.
To approximate +P with 125-gr. jacketed use 6 grs.
In .45 ACP with 230 lead 6 grs. approximates hardball velocity.
In cast bullet rifle loads you can use Unique data and not get into any trouble. I use 13 grs. with 150-gr. FMJ bullets in the .303 British, .308 Win., 8mm Mauser and .30-'06 as a plinker.
Have not used it in 9mm, but Lyman probably lists some loads. I would not experiment much beyond published loads in a small case like the 9mm.

PB is a little slower than Bullseye, I use it in much the same way.
I've used a lot of PB in shot shells. It seems to have a lower flame temp and is easier on hulls than say 700X. Also a lot of shotguners liked it because of lower felt recoil.
I have tried it in .38 and 9mm but never got good accuracy.
According to Hodgdon's burn rate chart PB is #17 where as Bullseye is #9.

As a commercial loader, I used one 8 lb keg bought by the senior partner for handgun loads. Although a good, if pricey, shotshell powder, it is not a stellar performer in most handgun loads.
I no longer use PB for commercial ammo. Low speed, high pressure in many cases.
