Agree with advice, especially getting the H20 level right (a bump of water protruding) with an average of at least 3 fire rounds from your chamber. Use QL for powder selection as that is very helpful (most speed for equal pressure across all powders). Use the edit function if using a bullet not listed, eg ELDM is slightly longer than same weight AMAX. Use cartridge near your one if not listed and then adjust to actual H20 capacity, case length...eg 260 Rem for 260AI. Do not use QL as a reloading guide, use a manufacturers reloading data - QL is a model and all models are wrong. Set all your parameters up in QL to match your load (COAL, case length, etc) then chrony that load and compare average velocity to QL prediction - adjust Ba value to match velocity - this should then be close to real world. You can use the barrel time of projectile with the OBT method to see if you are near the predicted nodes for accuracy Optimal Barrel Time Paper.
I am still very new to QL and learning all the time.
