Does case length effect bullet hold on 223?

[smovlov]

I loaded some 223 recently and I had a FC case that seems to seat a bullet too easily. I pressed it on the bench with a good amount of pressure (I didn't measure) and the bullet slipped inside the case. I tried with a few others and they didn't. The FC case measured below 1.750". Would a case shorter than that cause less neck tension (1.740"-1.749")? All the other FC brass I have is shorter than 1.750".

1.50" would be shorter then base to shoulder! = Zero neck tension.

MAX case length is 1.760".

Trim length is 1.750".

SO, you need to go back and measure again.

Regardless of all that?
No, a slightly shorter case will have no noticeable effect on case neck tension.

Got to ask - are you sizing the brass? If yes, how? If no, why?

Might seem like a useless questions but if something electrical isn't working it's amazing how many times it isn't plugged in and/or not turned on.

Well that was a duh moment! I edited and fixed it. The FC brass is around 1.745". Brass is resized with a Lee die and was set up with a Lyman case gauge.

Nah, that's not the problem.

 

[smovlov]

Yea. In re-writing it it's a minuscule amount. I was doing some reading and saw that a lot of people don't like Federal brass. Do you guys have problems with it?

neck tension. cases that let a bullet slide down them, may be good cases to crimp, the bullet. you may get 1 or 2 more fireing out of them if you crimp. (that is if you can hold bullet there long enough to crimp. )

If only one bullet slipped into the case to easily, it could be a problem with the bullet, not the case. Did you or can you measure the bullet O.D. to see if it's up to snuff?

 

[smovlov]

I measured the bullet but I don't trust bullet measurements from a dial caliper and I don't have access to a micrometer (I'm looking for one though). They measure out at .223 on the dial caliper. I resized the problem brass and tried again with another bullet and got the same result. I could feel the bullet seating much more easily than the others.

223 Rem takes a .224 bullet

22 hornet takes a .223 bullet

You may have the wrong bullets, but a 223 doesnt take a .223 bullet.

I don't think the short case is causing the problem.

I'm using a RCBS X-Die for .223. I trim my cases down to 1.740". I haven't noticed any neck tension issues.

22 hornet takes a .223 bullet

Very old ones do, but all the guns for some time have used .224.

If you have .223 Hornet bullets, it will say so on the box. I had an old Savage 23D that used them. Should have kept that gun.
