Recoil is acceptable comparing to some other loads I made for carry in woods.
According to some other data sources these velocities are still acceptable for this bullet so it wouldn't overexpand or fragment.
N105 is a low flash powder so shooting in darkness wouldn't be an issue.
IMO this load is good for SD in urban conditions.

And here are some pics:
