875*2^663162-1 is prime

from my reservation of individual k's for n=600k-620k:

363*2^612291-1 is new prime

825*2^665464-1 is a confirmed prime

979*2^667087-1 is prime

929*2^667460-1 is prime

383*2^736876-1 is prime

Breaking a long drought for new primes on the 6th drive:

733*2^632387-1 is prime

Edit: Karsten, I just noticed this: This is the 5th lowest weight k in the 6th drive and its first prime since n=272251! Interestingly for its weight of just 407, it now has a surprisingly large # of primes: 13.

After a nearly n=14K range without a new prime in the 6th drive, it scores its 2nd one in an n=1500 range:

777*2^633901-1 is prime

Primes are, oh wait, you've heard it.
