Reloading The .50 BMG

Loads for .50 BMG:

(Note: These are near MAXIMUM loads, you should use 10% less to start.) (See
note on Powders below or read all about various
Powders.) Bullet diameter is
.510 (some are .511) and this is the Big Boy used in the Browning Machine Gun,
ground, aircraft, and sniper rifles that reach a LONG way out.

While there are loads below for the 50 BMG, reloading it requires a bit more
care than most other ammo reloading. Here is a link to a shooter that shows in
detail with good photos, steps he takes to prepare the cases and reload the
ammo.

Discussion:

Alliant (formerly Hercules) Powders.
US869, H50BMG are products of Hodgdon Powders.
IMR (formerly DuPont) Powder Company (owned by Hodgdon).
Ramshot and Accurate Powder Company (Sub of Western Powders, Inc.)
Vihtavuori powders: For .50 BMG there are two special Vihtavuori reloading
powders available: 24N41 and 20N29. They are, like N100 series, single base
surface treated powders. Their burning rate is slower and grain size larger
than that of the N100 series rifle reloading powders.
