250 yards with the 357 iron sights is doable if the steel plate is big enough. What I want to see is the 45-70 at 400 yards with irons. I own my own shooting range out to 880. Where are you located?
Like I said, I need an optic to do 400 yards - but only 4x to do +1 MOA
I don’t care how big the plate is I’ll do +1 MOA with that set up. Even with these old eyes. Practice, practice, practice.
