Reloading velocitys ? HELP How much spread

[LibertyArms]

Just stareted to handload for accuracy myself. My rifle shoots hornadys 168 match so well that i cant duplicate it. ?? I started checking with a crono for the first time. How much of a spread should there be bettween loads. I shot today and it was a bit chillier. I shot 5 5shot groups. Now some shots where duplicates, but overal highest minus the lowest numbers where, 55,49,36,57,54. Velocity spreads.

Should they be better than that?
anyhelp on how to achive?
Im using a lyman dps II, it should shoot out within 1/10 of a grain.

Re: Reloading velocitys ? HELP How much spread

When you get your standard deviation down in the teens or single digits you'll have some accurate rounds. Twenties are acceptable. But that's where I stop at. I don't take any higher.

Pay attention to the details. Little details here, little details there and it all adds up.
