.223 Minimum OAL

[MI2600]

I searched the archives and a found a thread regarding this issue, but it left me confused.

The "book" maximum OAL is 2.260. One of the responses in the above search was that as long as part of the maximum diameter of the bullet is outside the case it will be safe.

My chamber will only accept an OAL of 2.200. Even at this OAL, only about an 1/8" of the bullet is inside the case. There is no bullet cannelure. Is this still good to go?

What firearm are you loading for?

2.125" OAL is the SAAMI minimum.

Just wondering...what bullet are you loading? I've not tried anything below 55gr so I'm still learning this stuff.

The old rule of thumb is 1 bullet diameter inside the case for adequate case neck tension to hold the bullet in place and provide good start pressure in the powder burn.

Once again, what kind of rifle do you have that will only accept 2.200" loads??

And whatever it is, it must not be able to shoot factory ammo????

I think there must be more to this story!!!

The gun is a Remington XP 100. The chamber was lengthened from a .221. The bullets are Sierra, 40 gr SP.

Nosler shows some very short OAL for some bullets in 223. http://www.nosler.com/nosler-load-data/223-remington/

as long as part of the maximum diameter of the bullet is outside the case it will be safe.

This should work, it keeps the bullet from falling into the case.
