I’m a big suppressor fan. Though I don’t use them with or on sub-sonic loads. The sherif in this county is a friend of mine, i understand the constant shooting at my place has been brought up in his presence. I think he’s happy that I’ve chosen to use suppressors a lot.
I have a couple 45-70 lever guns and a 45 Colt lever gun. I think either 45-70 or 45 Colt would work fine. Sub-sonic loads with either - would work well.
For your needs either sounds like it would work.
If I had to choose one over the other, my choice would be the 45-70 as my wants are different. The 45-70 is capable of plinking loads up to man-eating critter loads. Having written that, I’m too old, I’m too cheap, I’m too out of shape to go after man eaters.
You’ll likely be happy with either.
