I was hoping somebody who has QL installed would be able to run a couple loads for me.
1st: .38 Special, 158g SWC, 5.6g Power Pistol, OAL 1.445
2nd: .45-70, 530gr FN (RCBS mold), 38gr H4198, OAL 2.54
Thanks in advance!

38 Special, 5.6 grains Power Pistol, OAL 1.445, Lee 158 grain SWC O.665" long, 6" barrel: 14.6K psi, 950 fps. Note that if your actual bullet measures longer than this it could raise pressures rather dramatically in this case.
45/70 530 grain RCBS measuring 1.45" long, 38 grains H4198 with COAl 2.54", 24" bbl: 1700 fps 55K psi!! So maybe you need to rethink this 45/70 load even if you are using a Ruger #1 for it. Also looks like it would be fairly compressed (load density = 106%). And this is another load where if your bullet measures longer than the 1.45" QL uses, the pressures would rise dramatically.
I’ll have to look again at that .45-70 load. I’ve already tested that one thoroughly, and it’s perfectly safe in my gun. I couldn’t recall the exact powder I used from memory, and couldn’t find my notes at the time of the post. I likely used 38gr of IMR 3031, and not 4198. I was just curious what QL would presict for a velocity on that one.
The .38 load is one that I’m still working with, and the above information greatly helps with my development.

In that 45/70 load the use of IMR 3031 instead of H4198 makes rather a huge difference. The QL thinks the 3031 would run 30.5K psi and 1500 fps (24" bbl) which I'd guess would be safe in most anything newer than trap door Springfield; the 4198 at 55k psi could be too much for any of our golden oldies.
