Three points:
1) Federal often wimps out. No surprise there. Overall, I've lost all trust in Fed.
2) Some barrels "shoot faster" than others, which throws the "velocity per inch" guesstimates off. Ruger and newer S&W tubes usually shoot faster than Colts, Italian guns and vintage S&Ws. Look at Buffalo Bore's test data for their full house 357s and the pattern will be dead clear:

It seems to hold in other calibers too but it's easiest to spot with 357.
3) Handloading to BuffaloBore/GrizzlyAmmo/Doubletap performance levels isn't for the newbie reloader. They have pressure test gear you don't have. If you ARE going to try, best to start with a strong gun: Ruger large-frame SAs are perfect as they're a 44Mag-class frame that can be set up for lesser calibers. While the Service/Security series DAs aren't "weak", they're not the platform I'd test my own thermonuclear loads with. The GP100 would be better, SA Ruger better yet. (Note: while still classed as a "mid frame" SA, my New Vaq's cylinder (357) is beefier than a GP100 and shoots Doubletap-class stuff no problemo.)
