[QUOTE="asd9055, post: 2699828, member: 73445"] Quit Texan had excellent advice I am still learning GRT and first with the heat, then with the cold here in Houston, plus the scarcity of supplies, I have not done any testing in a while, but this is my process I will load at least one set of 5-10 rounds, same charge, same everything, if I have data of a "good safe load" I'll start with that. I will shoot those over a chrono. Take the fired cases and get the average volume of water. I use the data I gathered (bullet, charge, case volume, cartdridge length and fill in the tables. I got to measurements and fill that table Follow the procedures in GRT guidlines for obt, node, charge. Make three sets of 5 with suggested load, one at, one below, one above. Shoot over chrony, and look for the best group. Repeat if necessary. I do expect strong reactions to this. I did simillar with QL, but its a manual calibration [/QUOTE]
