Speer Gold Dot 124 grain JHP
This is just a repeat really of a previous test
but using a ten round sample rather than five.
Having done ten shot strings and wanting to keep
same format as previous, I will''double up'' with
the entries in tables below in the row showing String
Velocities - also rounding up or down with decimal
components of chrono readout.
As before, the figure for muzzle energy is formulated
by using the average velocity from chrono readings.

These results tie
in very well with previous five round strings from
the previous testing. Once again, two rounds at
extremes have stretched the spread from what is
otherwise a pretty close set of velocities. I like
the higher energy figure obtained from this ammo.
Expansion
test was very favorable. |
This
and the 115 grain version still come out as the
best choice in my opinion for use in the R9. Karl
and Eric agree on that also.
