Using the Razor HD with Other Calibers and Loads
The following drop chart for a .308 (7.62mm) Hornady
168 gr. AMAX bullet shot at 2700 fps. was generated on
a ballistic website. As you can see, the drops are close to
that of the M855 marked on the Razor HD 1–4 CQMR-1
elevation cap. Up to 600 yards, the difference is 1/2 MOA
or less, and for many applications would allow the turret to
be effectively used with the Hornady .308 168 gr. bullet.
Example
Although the Razor 1-4 CQMR-1 uses an elevation turret
knob calibrated specifically for two particular loads of
5.56mm ammunition, it can still be easily used with many
other popular calibers and loads. For example, most 55 gr.
loads of 5.56 ammunition will work well with the M193
references.
Listed below are the MOA drop numbers for the yard
reference marks used on the elevation turret cap:
Generating a custom ballistic drop chart for other calibers
and loads being used will allow the MOA drops to be
compared for compatibility.
