My old load form Tikka T3x CTR 20" was 47.6 gr Rl 26 at 2.280og at 2680fps.Scored six pounds from Powder Valley Last week,I had been searching for a year. Loaded up my same load and headed to the range.Shot 394,480,596,637. Was 1 moa high on all targets.Finally put Magneto speed on, velocity was 2750. Got home decided to reduce my charge and try to get back to the 2680 fps load which had been .3. Loaded up 2 one at 47.3 another at 47. 47.3 shot 2761,47 shot 2755. I was shooting off my porch where I can shoot 323.It usually takes 4.5 minutes to hit center on this target.I dialed 4.5 and shot. The shots were side by side 1 moa high.So I know nothing is wrong with the chrono. My question is . Has anyone ever reduced powder and gained velocity.
