[QUOTE="Len Backus, post: 30094, member: 1"] How low do you tune the muzzle velocity ES (10 shots)of your loads in order to shoot small groups at 1k? Ballistics programs tell us that a 30 to 50 fps velocity difference will cause a vertical spread of quite a few inches, depending on the bullet's BC. How much correlation do you actually see (as opposed to theory) between ES and vertical dispersion at 1k? [/QUOTE]
