With lake city brass I had to go with a small base sizer die because my FL die would not get the brass to Sami specs and prevented the bolt from going into battery on my M1a. Factory ammo was no problem. Lesson learned the hard way.
As said before most of the small CUT tractors are made off shore. I have a GC2300 from Massey on three and a half acres with a loader and belly mower it has been a back saver for me.
