Thread: HELP OAL gauge and bullet comparator problem...

Hi,

I've been using the Horny OAL gauge since I started reloading, and I have never once got a consistent CBTO measurement. The way I measure my lands now is to make 6 measurements. Of the six there is invariably one measurement thats long than the others by 10-20 thou (0.02") I just use the rest, and take the second Shortest:
Example (223 Rem) CBTO for Hornady Vmax 40's (measured)
1. 1.885"
2. 1.886"
3. 1.884"
4. 1.887"
5. 1.894"
6. 1.886"

In this case I used 1.885" as my lands measurement. The "Wildcard" long seater was 1.893 (Number 5, above)


The following method is a(nother) good way to find the lands - if you've got the right rifle for it (Doesnt work so well on my tikka due to the way the ejectors set up)
Bullet seating depth Method

Also, would suggest you talk to @ebf .. he's also currently having issues getting Berger VLD's to group out of his 308 .. and he did mention they are touchy regarding seating depth.

Finally (whew) keep us informed of your progress ... I'm doing a load soon for my 243 using Targex 95's (which are a Berger VLD Jacket)

regards

Tim
