OAL Starting point 0-500 yd 6.5x55

So, I don't post here a lot, but I thought you all were the right place for this question..

I have a Ruger M77 6.5x55 (stock African) that I'm starting load development for. Normally I start a load development land touch - 0.030"

I could do that again. Basically, my method is guess a starting point, then change variables until I find roughly the best of each variable or groups that beat my expectations.

So, how do you determine starting point for OAL? My first variable is selecting between Nosler Accubond 140 and Hornady ELDX 143.

The last thing I read was start at "jam" because that is max pressure, then dial out after tuning charge weight.

My first round is bullet selection, so I'm going to set as SAAMI, I guess. Then mess with it more, maybe setting to jam for next round.
