anyone know for sure why some 10mm barrels are ramped and some not in 1911's. my kimber eclipse is, i bought a dan cbob thinking it would be but it isn't. found out they weren't ramped till 08 . as far as i know a delta isn't, i've heard strength rumors but adding to one side of a cylinder can't possibly make it stronger. if its for feeding, why don't all 1911's have them?what am i missing here?
ramped or unramped barrel in 10mm? why?

There are a couple factors that determine when to ramp.
First, a single frame can be used for various barrels. Secondly, with lightweight alloy frames there's no need to concern yourself with frame ramp damage from hollow-point ammo. Finally, a ramped barrel, and it will vary from make to make, will offer more chamber support, something critical for higher pressure rounds. (like 10mm)
Hope that helps.

It's my understanding that those 10mm DWs that experienced problems and were returned were retrofitted with ramped barrels, Wilson/Nowlin (style) I believe.
