Ruger 77/50 - Manual (Page 13)

Know the bore diameter of your rifle you are loading and
load projectiles of only correct diameter into it! Either a
too tight or too loose projectile can cause a burst barrel,
resulting in serious injury to the shooter or bystanders.
This rifle is designed to use a .500” projectile (or a .490”
projectile with a .010 - .015” thick patch), a #11
percussion cap, and up to a maximum of 120 grains of
FFg black powder (or equivalent volume of Pyrodex RS)
only. Never use smokeless powder of any kind.
Before firing, be certain the percussion cap is seated
completely on the nipple. A rifle discharged by the
closing of the bolt on an incorrectly seated cap can
result in possible serious injury to the shooter and those
nearby.
If a projectile does not fully seat readily, do not force it.
Check to be certain that each projectile is the proper
caliber and of correct dimensions. If you cannot
determine why the projectile will not fit, carefully
remove the projectile, empty the rifle of all powder (see
pp. 20 - 22) and write or call the factory.
The wrong components or an excessive powder charge
can destroy your gun and result in serious injury to you
or bystanders.

is on the nipple!

securely with the barrel pointing
straight upwards and the recoil
pad or butt plate on the ground.

parts away from the muzzle!
