Needing 80-82 gr .223 oal numbers

[tenshot]

I am in need of some more data and could use a little help.
8 twist, mid range (600 max), .223 rem, .120 free bore bolt gun build.
Bullets will be the 80's, the Burger 80 VLD, 80 FB, 82 LRBT, Sierra 80 MK and Hornady 80 AMAX.

I would like to know the OAL of your loaded round with the bullet used, maybe jam/jump and free bore length if other than .120 , I am trying to get a better idea of how the round is going to fit an action and possibly a magazine.
I have just a few numbers I found starting above 2.420 but the sampling is small and the free bore unknown.

Thanks in advance
Lee

I don't think there is anyone that can give you that oal. Example my freebore is approx. .150 so the oal will be different. I just use a case with a split neck take one of the bullets you are planning to use, start it in the case them put it in the chamber and close the bolt, remove the cartridge and measure the oal this will give you a place to start. Or Hornady makes handy tool for measuring OAL. Good luck.

I can give you a little info. My 223 with .071 freebore and and 80 smk's touching the rifling the AOL is 2.490, which puts it about .125 to long for mag length.

My other 223 with 80 smk's and .169 freebore has an AOL of 2.577. Its about .025 off the rifling.

The Berger 80 vld's have a ~2.553 AOL with the .169 freebore touching the rifling.

The 80 bergers will be farther in the case vs. the Sierra's if both are touching the rifling.

Hope that helps a little at least.

All I need is a base to tip number for a .223 with one of the 80 weight bullet, guess I could have just said that to start.
This has nothing to do with load development, the free bore was just to see if a given length was longer than what I will be using.
All I need is a larger sampling.

Boltman that is just what I'm looking for thanks.
80 SMK .120-.071=.049 2.490+.049=2.539 oal length approximately, plus minus of course jam/jump considered
80 SMK .120-.169=-.049 2.577-.049=2.528 2.528+.025=2.553 oal
80 VLD .120-.169=-.049 2.553-.049=2.504 oal seated deeper in the case than you seat the SMK on the other 2 loads and the magazine you run allows an OAL of 2.365
just as an example of what I'm doing,
Any numbers welcome from simple oal to as much as your willing to share.

Thanks again
