I'm looking at load data for 308 winchester.
Max OAL is 2.810
Recommended is 2.800
To hit the middle of the cannelure is 2.713
A buddy of mine wants me to reload for his 308 He bought some "old" dies at an auction. He told me that he will buy the primes, powder, and the bullets (from Sage of course). So now I'm trying to figure out what depth to set them at.

Load data from Hodgdon online data for H4895
What bullet are you using? The cannelure shouldn’t dictate your seating depth, you can use the COAL that the bullet manufacturer gives for that particular bullet, or measure the throat of your buddies rifle and adjust seating depth based on that.

AOL is determined by the reloading data you are using.
Every book for the same bullet can be different, and pressures were achieved by seating depth
What bullet and powder do you plan to use?
Load data from here http://www.hodgdonreloading.com/data/rifle
.308 150gr Hornady FMJ-BT W/C (500CT) PRE-PACKAGED SPECIAL
He wanted CFE223 But I told him that it is temp sensitive So now H4895

I have Hornady's ogive guage tools. And I checked his barrel.

Every day is a good day. Some are just better than others.
As long as you aren't loading to max, and want to seat to the cannelure, that is fine.
There is no need to load to the cannelure either. They are set and designed for 30-06, not 308 but you can seat at any length you like

A minimun col would be nice.

The hornady 9th edition says to load that bullet to 2.700”. Starting load of h4895 is 37.2gr and max load 44.0gr.

What did your comparator say the max OAL can be?

Trying to learn about OAL and why it's a pain in my back side. It would be great if they published a minimun and a maximun CMark

They can’t put a maximum out there, because every rifle’s throat is different. So you either have to load to what the book says or measure the throat to find a maximum for that particular rifle.Quote:

I think you're talking about what I call, the jump space. I am talking about COL. Like the .223 OAL is 2.260

His AR10 is 3.240. And his AR15 is 2.900

Now I think I'm confusedEvery day is a good day. Some are just better than others.Quote:

If you seat your bullet to the OAL that the manufacturer says to load it to, then you will be safe with more jump space. If you seat your bullet farther out than what the book says, it will reduce the amount of jump space. For AR style rifles your max COAL is usually limited to magazine length. When I load for my AR’s I just go with what the book says and don’t bother with measuring for max. In this case it would be 2.700”.Quote:

They can't test every bullet for every depth as is would cost too much, and would be a waste of their resources.
Max COAL is usually BS too, it is usually just Mag or box mag lengths.Quote:

Thank you

I load that same exact bullet with that same powder for my AR-10. I get good accuracy from that combo.Quote:
