I have always used RCBS Uniflo never had a problem with powder missing case.I load 222,223,22 hornet they all fit the bushing in the measure.There are two sizes of bushings make sure you have the small one screwed in.Hornet ammo around here is abour $25.00 box so I can save alot by reloading.Anneal the necks that will give you a little more case life.Good luck with the hornet I have a 10" contender barrel and it is a little picky about what I feed it.
