Please do not be one of
those hand loaders who is going to search through this information just
to find the stated "MAXIMUM" load and start with that.
There is much more to
determining your maximum load than just how much powder you can dump in
Temperature, bullet type,
bullet weight, bullet seating depth, barrel twist, grove diameter,
chamber throat profile. These are just a few of the variables that can
affect velocity and pressure.
In our never-ending search for
high velocity, anyone can overload a cartridge to achieve "BRAGGING
In doing so however, you risk
damaging your rifle, endangering yourself and those around you.
The following information will
assist you in working up an accurate, high velocity load for your rifle
in a safe and prudent manner.
A good set of reloading dies, a
quality set of calipers, an accurate powder scale and a reliable
chronograph are some of the items you will need.
Begin by firing the first shot
with the starting load and record seating depth and velocity.
Increase the powder charge no
more than 1 grain at a time. If you experience ANY ONE of the
following signs of pressure, reduce your powder charge by 10% and
consider that your maximum load. Never exceed the maximum
load stated in the following chart regardless of whether or not any
pressure signs are apparent.
you begin to see pressure signs on the primer such as flattening
or "cratering" around the firing pin dent.
enough brass flows into the ejector pin hole on the bolt face so
as to cause a shiny spot or dent when the cartridge is ejected.
ejecting the fired cartridge, the bolt is sticky or hard to
