I have used Trail Boss in revolver/rifle combinations as follows--32/20, 357 Magnum, 44 Magnum. All three calibers yield roughly 800-825 FPS from 4"-5" barrels when loaded at 100% density, and 18"-20" rifle barrels gain about 250-275 FPS in those same calibers.
Pressure and velocity per grain of powder has been likened to Red Dot. I think of TB as a fluffy analog of RD. It is a useful powder for kind of a narrow niche, which can also be said of WW-296/H-110. I greatly enjoy sending SWC castings from magnum revolvers at "Skeeter's Load" speeds--850-1000 FPS. All day recoil, much less donner und blitzen, and VERY accurate.

I think Vhitavuori's NC32, (Tin Star), is about the burn speed of Unique. Big kernels, bigger than 4759. I bought several pounds of it cheap a few years back. I was playing with it this morning. I put 12 grains in a .308 under a bullet that's supposed to be NOE's interpretation of Ed Harris's original 160 SKS bullet before Lee modified it. I have a 4 cav mould two checked, two plain base. I was shooting the plain base this morning. Trying to work up an offhand plain base load to save the 3 cents per gas check tariff. Shot okay, seemed too fast, little flecks of lead on a patch afterward. But one patch and they were gone. Nose seems a little fat, heavy engraving in the .308. Maybe better in the roached throat Springfield.

I have used N32c a bit. I have gotten good results, but apparently no better than other shotgun/pistol powders I use. Like other Vihtavouri powders, it is top quality. According to the Vihta burning rate chart (which they seem to have withdrawn from their website), the burning rate of N32c falls between Trailboss and Unique, about the same as SR7625. It is not only a low density powder, but also has a reduced energy/weight ratio, about 25% less energy per weight than other Vihta powders.
Vihtavuori has an informative web site, where (among other things) mass density and energy is stated.

For this reason (low calorie), you’ll find you need a bit more powder than you would expect, judging by the burning speed alone. Which, in turn, could lead to the erroneous conclusion that it is slower than it really is.
For plain base, lubed bullets in the .308, I would try the 9-11grs interval.

Thank you Spindrift. Valuable information. My "local" powder shop had a bunch of Tin Star on sale cheap a few years back, also another Vhitavuori powder I think was called SH3. I will always buy a fast burning powder at 10 bucks a pound and figure out a use for it later.I have used N32c a bit.

I’ve seen this in some films, where the hero was able to dodge bullets. Makes sense, now

That's funny right there. Kinda defeats the purpose of running a 44 or 45 caliber sideiron, in my view--but I'm kinda narrow-minded in some respects. CAS folks were shooting and having fun, and that's what matters at day's end.
The 45 Colt with a 100%-density Trail Boss loading gave not quite 900 FPS to both Lymans #454190 and 454424 in a 7.5" barrel. 255 grains of 45 caliber bullet at 900 FPS is no joke on the receiving end. I was greatly envious of Anaheim PD and their use of the S&W Model 25-5 at the time I got started in the LE bizness.

Easy to do when the bullet is computer designed to weigh less than 1/10 of what a standard for caliber bullet would be.
