Best way to measure bullet distance from lands?

Trying to load various weight/styles of match bullets and determine what COAL has the bullet near/or touching the lands on a particular M40 style .308 rifle.

I bought an RCBS tool consisting of a slip fit dummy round you measure before and after chambering. This tool measured from it's dummy rounds ogive rather than oal. The measurement method seemed nonsencical to me. It also measured head-space, which was useful.

Then started using spent brass with the different bullets I was considering same fashion, i.e. bullets slip fit and measure COAL before and after chambering.

While this doesn't really give me distance to lands it gives me, I think, what I need to know for loading - the max theoretical COAL for a particular bullet.

Am I wrong?

Mitch's link is spot on. I have the Sinclair bullet seating depth tool, but I use it more as a backup. I prefer useing a case that I have drilled out the flash hole so I can push out the bullet with a drift pin.

Hornady OAL Tool is the easiest to use... I give it my thumb of approval

Hornady bought out Stoney Point, and thus what was SP became H.

I take a properly sized case for the rifle and put two cuts down the neck into the shoulder with a dremel tool and deburr inside and out. Place the bullet you want to measure into the case and close the bolt. Extract and measure max coal. I usually measure 3 or 4 and take the average.
