Ran a quick 100 on my Loadmaster today (only my 4th session reloading). First time I had absolutely no problems! (at least until I try them out!) My other sessions were no fault of Lee's though, mostly my setup/learning curve issues. 5.4-5.5 gns of Win231 with Hornady 230 FMJ RN with CCI primers, range brass (washed and tumbled).
