Half a turn is plenty.
They look good to me.

I load at Trapdoor levels so a quarter turn is what I use.
I'm also all about 45-70 case life so I work the case as little as I can get away with.

that crimp looks good and should be fine for full power loads ..... it will most certainly work for lighter loads but you might be able to back off a bit for lighter loads

It's my understanding that lever gun bullets (hand gun also?)are crimped to prevent the bullet from being pushed further into the case from recoil. So getting the case below that front edge of the cannellure is the goal.
A half turn is not over doing it for heavier loads.

IMHO you should back off the crimp, especially with the cast bullet, just a very light is all that is needed. I usually do not use a heavy crimp in my 45-70 loads and agree with others, work the brass as little as possible.
