Cast shooters have a little different outlook towards accuracy in a lot of cases. There are people out there who strive for benchrest accuracy with cast, it is an endeavour fraught with ups and downs, just have to have the patience to pursue it. Definitely teaches a person about wind and how to shoot it, some are content with loading in the 13-1500fps range, some want to get to jacketed velocities, some build cartridges, some breech seat their bullets. I played with 55gr gaschecked bullets in a 22-250 for cheap plinking at gophers and 130gr in a 7x57 & 7-08, one for iron sight service rifle matches and one for grouse and the odd yote, and plainbase bullets in a 32-30Rem and 32-40win for Schuetzen matches, and a 450-400ne 3" with gaschecked bullets. Velocities ran from 1400-2200fps, depending on bullet and purpose. I needed minute of gopher head on one, holding under 5" offhand at 100 on another, holding a 1-1/2" bull @ 200 on another off the bench, another was the ability to punch a moose at 150. Ran bullets that were oven hardened wheelweights, then to 1/30 for hunting, 1/20 for the Schuetzen matches, straight wheelweights for the service rifle.
