How do you count those? Can you search by vowelized text? – Isaac Moses Oct 24 '12 at 18:04

There are approximately 305K letters in a Torah scroll.

A more interesting source IMO aishdas.org/toratemet/en_pamphlet9.html – Double AA Oct 24 '12 at 19:18
The number they give (304805) is based (they claim) on the Masora of Ben Asher in his Dikdukei Taamim. Can anyone confirm that our received text has the same number? – Double AA Oct 24 '12 at 19:26
@DoubleAA Here's something posted today on Hirhurim that indicates another source for the same total. Anyway, it'd have to be off by hundreds to remove the association with 305. – Isaac Moses Oct 24 '12 at 19:29

In 1929 - 305 American Jews made Aliya. source - jta.org
