This is the blurb given in "Basic Physics 2 by S.L.Martin and
A.K.Connor", (1960+ vintage), briefly describing the purpose of
the Pound and Rebka experiment.
"In 1958 an effect was discovered by Mossbauer, working in U.S.A
and known as the Mossbauer effect, which enabled very tiny
frequency differences to be detected and measured. In 1960, using
the Mossbauer effect, Pound and Rebka succeeded in measuring the
extremely small change (only about 1 part in 4e+14) of frequency
of the y-rays emitted by a sample of radioactive iron when it
was moved from the bottom of the tower to the top of a tower 74
feet high. The observed frequency change agreed with the
relativity prediction within 5%."

According to your equation  f'= f(1+V/c^2)
  V(a) and V(b) for the tower base and tower top is:
  G = 6.67E-11
  M = 5.97E+24
  ra = 6378000   Tower base radii
  rb = 6378023   Tower top radii (+23 meters (74 feet) high)
  Va = G * M / ra ^ 2  = 9.7888378648735791276869837432118
  Vb = G * M / rb ^ 2  = 9.7887672652959533370556770582427

The problem is that, according to your equation, even a
1.4e+21 hz gamma ray only generates a change of 1 part in
1.4e+21.

  f = 1.4e+21
  f'= f(1+Va/c^2) = 1400000000000000152270.8112313668
  f'= f(1+Vb/c^2) = 1400000000000000152269.7130157148
The difference is 1.098, which is near enough to 1 added cycle
in 1.4e+21 cycles.

A 1.4e+21 hz gamma ray generates a frequency change of only 1
part per 1.4e+21 cycles, when the observed change was 1 part in
4e+14 cycles. That's 3.5 million times less than observed. That's
a long way short of the 5% accuracy claim, isn't it?

But what did the experiment prove anyway? It seems to have only
demonstrated that the gamma ray was created in an entirely
different environment to the one in which most other natural
oscillators function.

The charge structure of the Caesium atom configuration that
drives the oscillator of an atomic clock, obviously functions in
the realm outside a proton or neutron, as apparently do the
natural oscillators which generate the characteristic spectral
lines of an atom. All of these oscillators obey the same rule,
that the rate of oscillation increases with increasing distance
from a gravity source.

The wavelength of a gamma ray is short enough to have been
generated entirely within a proton, requiring that there be
some sort of charge structure configuration within, which will
resonate in tune within the proton (black hole) confines. We only
see it when part of it escapes.

It's more likely that the increasingly "intense" environment
deeper into a gravity well is going to increase, rather than
decrease the forces acting to restrain the proton contents, hence
the frequency increases.

The truth is that time (not clocks) runs faster with increasing
depth.
