ruger mini14 target is fussy, .223 is ok but not the surplus mil
ammo,5.56mm*45, which looks identical.

details;

The cartridge casings for both calibers have basically the same length
and exterior dimensions.

The 5.56 round, loaded to Military Specification, typically has higher
velocity and chamber pressure than the .223 Rem.

The 5.56 cartridge case may have thicker walls, and a thicker head, for
extra strength. This better contains the higher chamber pressure.

However, a thicker case reduces powder capacity, which is of concern to
the reloader.

The 5.56mm and .223 Rem chambers are nearly identical. The difference is
in the "Leade". Leade is defined as the portion of the barrel directly
in front of the chamber where the rifling has been conically removed to
allow room for the seated bullet. It is also more commonly known as the
throat. Leade in a .223 Rem chamber is usually .085". In a 5.56mm
chamber the leade is typically .162", or almost twice as much as in the
223 Rem chamber.

You can fire .223 Rem cartridges in 5.56mm chambers with this longer
leade, but you will generally have a slight loss in accuracy and
velocity over firing the .223 round in the chamber with the shorter
leade it was designed for.

Problems may occur when firing the higher-pressure 5.56mm cartridge in a
.223 chamber with its much shorter leade. It is generally known that
shortening the leade can dramatically increase chamber pressure. In some
cases, this higher pressure could result in primer pocket gas leaks,
blown cartridge case heads and gun functioning issues.

The 5.56mm military cartridge fired in a .223 Rem chamber is considered
by SAAMI (Small Arm and Ammunition Manufacturers Institute) to be an
unsafe ammunition combination.

civil war, .65 caliber round ball !!
