OAL masurments?

[cpttango30]

A little background on the rifles. First my 223 is a stock Remmy 700 with a timney trigger and a Callahan Traditional Non-ISS Firing Pin Assembly. The 308 is a semi-custom rifle built on a Remington 1917 Enfield military action. It has a custom barrel which is either a Douglas or Hart,Not sure which as there are no marking on it).
OK guys I got a Hornady LNL OAL Gauge,Stoney Point).

Here is what I am getting for measurements. I am using the bullet Comparator to do this. I seated the modified case in the chamber and then moved the bullet untill I felt it touch the lands.

In the 223 using 50gr V-max
OAL gauge = 1.887"
My loads = 1.851"
Difference = 0.036"

So my loads are .036" off the lands. Is this to far or to close?

Now the 308. 155gr Sierra Palma Match
OAL Gauge = 2.228"
My Loads = 2.184"
Difference = 0.044"

My loads are .044" off the lands good or bad?

Where do you guys like to have your bullets sitting off the lands?

There is no set OAL that works with every rifle. Your rifle will tell you where it likes each bullet make seated. The first thing you need to do is find a load that is pretty accurate before you go trying different seating depths. Many rifles will shoot pretty good with the bullet 10 thousands off the lands. Find a powder, case, primer, and bullet combo that shoots well with the bullet 10 thousands off the lands. Then start with bullets seated just off the lands and shoot some groups then seat it deeper 5 thousands at a time and shoot groups until you find your most accurate spot. When you find that length be sure that it is not too long to work through the magazine if you will be shooting from the magazine.
