I only load per the manufactures data. Never had a problem, because they already done the work for us. Stick to published data and save time and headaches.
Ditto, my patterns were always as expected with published recipes, thus no need to deviate. Chasing that extra 50-100 fps had no chance of improving patterns, so why bother. All the competitions I shot prohibited reloads and limited velocities. And fellow competitors DID check each other out, especially the top guns.
