Accuracy International 308 LANS measurement

[cwq]

HELP.

I have an Accuracy International AE Mk III with a 24" barrel, 0.308 Winchester.

I reload my own bullets and can get 0.6 to 0.5 MOA with hand loads. I thought that I would be clever and actually measure the LANs in my riffle. I measured a number of times and the results are;

168g Sierra Match King HBPT
2.355 to the LANs and bullet length 2.930

178g Hornady A-MAX
2.310 to the LANs and bullet length 2.920

The maximum bullet length I can use is 2.810

if I back off 0.020 from the LANs I would be say 2.910 on the Sierra Match King.

I want to seat bullet at 0.020 from the LANs but cannot!!!!!!!!!!!!

So my question(s) are;

1. Does the AI have a lot of gap to the LANs?

2. Am I doing it wrong (don't believe so)?

3. Any other ideas?


Many Thanks

I can not understand what you wrote. But AI rifles are purpose built for combat. They are designed to shoot any ammo in any condition. Their chambers are "generous". I personally would stay within my available magazine length and find the best load by trying different powders, unless you really want to single feed.

Why don't you cast the chamber using cerrosafe? It will give you an exact replica of your chamber.
