Lans vs. Lanes and Groves

**Rolsby** · March 22nd, 2009, 03:01 AM

While working at a civil war museum, the interpretive coordinator told me it was lanes and grooves in rifled cannons. All my experience up to that point had been rifle and pistol but I still thought it was lands *edit* and grooves.

Anyone want to weigh in? If possible, could you post primary sources/scanned materials?

You're BOTH wrong!

It's Lands and Grooves.

...Rifled bores may be described by the bore diameter (the diameter across the lands or high points in the rifling), or by groove diameter (the diameter across the grooves or low points in the rifling.)

lans sounds a lot like glans.

it also sounds like "lands" which is the word you are looking for.
lands and grooves. the projectile contacts the LANDS, and expands into the grooves.

Glands and Boobs!

Crum hit the nail on the head.

Sorry, I can't in good conscience use Wikipedia as a primary source.
