Since the 158gr are plated and just target loads no big thing.

My J frame snub nose shoots ALL over the place with different
bullet weights and powder. I only have a handful of loads that
shot at point of aim with target or maximum loads.

Even if not at POA, the main thing target loads are for is to get
to know your weapon and establish the target, trigger, brain trip.
Learning trigger control, stance, grip is a lot easier with light
loads with minimum recoil. When you feel comfortable you can
test out a few SD loads and see if any are near your POA and
if the recoil and noise will work for the shooter.

If you find a SD that works, maybe then you can match its POA with
a target load that you have logged that shots the same.

Good loading.
