15mm Rifle

Speaking of large caliber rifles, I recall that the Finnish in WWII had a
excellent 20mm Anti-Tank rifle, called the Lahti, I believe.  It was bipod
mounted and semi-automatic, also.  I'm not quite sure how they handled the
recoil, or anything else about it, however.  Anybody know anything more?
