Does anyone have the latest Hornady manual? What is the listed COL for the 75gr A-Max for .223 Remington, and the minimum/maximum for Hodgdon Varget and IMR 4064 with the respective velocities?
Thanks.
Thanks.

I'm on the sixth edition so maybe there's a newer one?
The reason why I wanted to know the COL listed by Hornady is because I am trying to load these to magazine length for an AR. While knowing the maximum charges listed by Hornady is important, I want to know the COL Hornady used when developing their data so that I know, ballpark-wise, how the data will be skewed when I seat the bullet deeper.P032177 said:The Amax 75gr is meant to be seated near the lands of the barrel, and the OAL would best be determined by using a Stoney Point tool on your barrel!
Go to the Hodgdon web site and look up the 223 data using Varget. Work up the load and seating depths based on target results.
I think about 10 thousandths off the lands ought to work well! Your velocity will be a function of your barrel! You need to chrono the loads!
There are no shortcuts to safely reloading ammo!
Well, I just found out you can't seat the 75gr A-Max to magazine length for the AR. You *can* seat the bullets down to 2.250", but what happens is that the ogive of the bullet is seated below the lip of the neck of the case. I made 3 dummy rounds, loaded them in the mag and fast cycled them. One seated fine, then I cycled the bolt and the next one jammed. I pulled hard on the ophandle and when the 2nd case ejected, I found the bullet jammed all the way unto the case. There isn't enough neck tension if you seat the A-Max to mag length.dmftoy1 said:I'll be curious how it turns out for you. I"ve been playing with winchester 55 fmj bullets and have been able to seat them out to maximum COL and they seem to function fine in my AR magazines. I did notice that the XM193 ammo (which I'm trying to duplicate) is seated .013 shorter.
Have a good one,
